New Grower Bagseeds in a 2x2x4 with one Autocob - Coco Hempy Buckets

[bad dragon bzzz]

tiny rusty looking spots 9/10 times is cal def.coco needs lots of cal/mag and like lower ph to.
light may not be too close,as plants are a tad more on the leggy side than squat.a gentle pointing towards the light is natural,a cupping/taco effect is to much light.
good luck n keep er lit.

Congratulations on getting back into it. Everything looks great and I’m sure it will all come back to you.

I like leaves pointing up (praying). If there are no other signs, I wouldn't deduce light stress from that.

I never have had to use cal mag, but I am a DWC guy. I don't think I have seen a journal of a coco grower who hasn't had to use it though. I will let someone more familiar with the medium comment. It should be easily correctable, though!

oh yeah, calcium def must be it. Not only is this cococoir i'm using not buffered and i'm not supplementing cal-mag, but when I compare the ppms per element of my nutes with other nutes, I notice these have under half the normal ppms... (CNS has 315 while these have 120). For now I'll just have to wait a bit, my Cal-Mag supplement arrives mid-january. But it's nice to confirm and learn about this aspect of coco. Also, I will be buying buffered coco next time.

oh, and about the leggy growth... I was kinda expecting this autocob to be like other LEDs and produce shorter plants, with very short internodal spacing, so talking about this topic with my friend and how they are not quite as squatty as expected, my friend (who gave me the seeds and the older seedlings) says he believes it's because most of thesese seeds are sativa dominant hydbrids. he has grown many of these seeds in the past and most would turn up males, only once did he get a plant that seemed to be an auto, and the rest would be very tall females with skinny looking leaves and mangoe smells. Here in my country we have a landrace strain called Mango Biche, which is a Sativa as far as we know, so it's not crazy to assume these seeds have a bit of that genetic trait in them. Obviously that wouldn't be ideal for my grow space, that's why I'm strating with these small containers. Not sure if that is what would explain their leggyness. I have a Purple Afghan Kushfrom Dinafem that I hope will be squat to confirm this.
Or maybe it's the 3500 k of the light? Maybe the 6500k autocob produces squattier plants than the 3500k I have? I will do some further reading in the cobshop.net section of the forums, maybe it has been docuemnted already.

UPDATE

On the 28th I lowered the light to 66 cm (25.9 inches) above seedlings, 60 cm (23.6 inches) above older plants... I began at 30 inches and believe it was definitely too far, thus the stretch of the plants. This change doesn't seem to have caused any stress... temps have even lowered inside the tent... strange but noice! Oh... and the chamomile 's growth exploded after this, and the basil also started producing a lot of odor... it's like there is pesto soauce in my room!
I'm still feeding Group 1 with 0.8 EC and pH between 5.8 and 6.0, and Group 2 and the other aromatics with 0.4 EC. Transplanted the basil into a biger container and hopefully its last one.

Group 1 (two older plants):​

Plant "D1R" aka "the mutant" (usually to the left in the pictures):
-grew 6 cm (2.36 inches) since dec 28th.
-has light signs of Mg def. Calcium def symptoms have not spread.
Plant "X1RS" aka "the warrior" (usually to the right in the pictures):
-grew 6 cm (2.36 inches) since dec 28th.
-has heavier signs of Mg def. Calcium def symptoms have not spread.

Group 2 (two younger plants):​

Plant "DR1R" (brown bucket, seedling grew in cococoir, then transplanted into coco hempy):
-grew 6 cm (2.36 inches) since dec 28th.
-has a slight discoloration. bnot sure what it is.
-the second set of true leaves appears to be growing irregularly with just one leaf.
Plant "DR2R" (white bucket, seedling grew in peat/perlite mix, then trnasplanted into coco hempy):
-grew 6 cm (2.36 inches) since dec 28th.
-it leaves have some twisting from day 1 which haven't flatened out, but seems to be growing healthy.
-the second set of true leaves appears to be growing as it should adn is already producing is third.

That's all for now. Please feel free to comment.

UPDATE
Light distance
Seeing that I might be able to lower the light even more, on the evening of the 31st I tied down the two older plants (group 1) and left them to have the same canopy height as the seedlings (group 2), and then I lowered the light to be at 56 cm ( 22 inch) above all.

In the morning of January 1st, tied down plants had recovered well and were a bit taller than the seedlings, and I think none of the plants were showing signs of light stress. So, I lowered the light to 50 cm (19.6 inches) above seedlings.

So far, (January 2nd, 1 pm) the light distance doesn't seem to be bothering them. Today the seedlings are at about 48 cm (18.8 inch) from the light and the highest part of the older plants is about 45 cm (17.7 inch) from the light, so I guess growth has not been stunted.. meaning light distance is still good. I think ill stop lowering the light.

Edit: at 5 pm today (Jan 2), I had second thoughts about the light height and decided to pull it back a bit. Now it's 56 cm / 22 inches away from the tops of the seedlings, and 52-54 cm / 20.4-21.2 inches away from the tops of the older plants.

Feeding
Seedlings (group 2) are still receiving daily watering/feeds with 0.4 EC and pH at 5.8-6.0, and older plants (group 1) were still getting daily watering/feeding at 0.8 EC (mid 400's ppm's) but will start getting a higher dose from tomorrow. The tied down plants started eating much more after being tied down.
Today's runoff readings for the older plants were 175 ppm for "D1R" aka "the mutant" (usually to the left in the pictures), and 215 ppms "X1RS" aka "the warrior" (usually to the right in the pictures).

News
New member and future sole resident of the tent: Auto AK from GeaSeeds (germinated yesterday, today it's starting to sprout, hopefully will have sprouted by night). All the other cannabis plants (group 1 and 2) will be sent to my friend's cabinet in about 15 days. I will begin a different journal for the Auto AK in a few days. I plan to keep the light at the current distance for her (70 cm/ 27 inch from the floor) and work around that.

So, that's it for now. What do you think? lights too close? Am i missing some light stress symptoms?

UPDATE
Light distance
This morning I realized I went too close with light distance. The leaves closer to the light started canoeing in the older plants, and canoeing and getting yellow in the younger seedlings. Also, i was seeing at least a 1 cm growth each day, today they are stunted. Sooo, I will go back to following @BigSm0 's guide and set the light back to 30 inches from young seedlings, and try 28-30 from the tops of the older seedlings.
Edit, 1 pm: light is at 31 inches from the auto ak sprout, 27 inches from the tops of the older seeldings, and 29 inches from the tops of the younger seedlings which were just tied down. Last picture was taken at 1 pm.

Feeding
Young seedlings (group 2) are still receiving daily watering/feeds with 0.4-0.5 EC (200-240 ppm) and pH at 6.0. The older seedlings (group 1) are getting daily watering/feeding at 1.0 EC (470-515 ppm's) at pH of 6.0. The runoff of both groups of seedling is coming out around half of what was put in the previous feeding, so I assume I should increase the dosage for both groups.
Maybe the light being so close made the plants hungrier, so maybe i should wait to check tomorrow's runoff now that the light has been placed further back again.

UPDATE
Light distance
I try to keep light at a minimum of 28 inches from older plants. New sprout always at 30 inches or more. The Basil plant seems to be a bit sentitive to the light even at 32 inches.

Feeding
Young seedlings (group 2) are receiving daily watering/feeds with 0.7 EC and pH at 6.0. The older seedlings (group 1) are getting daily watering/feeding at 1.2 EC at pH of 6.0. The runoff of both groups of seedling is getting closer to input feed and plants look much better and growth is exploding. Will keep this dosage for a week and then increase if needed.

News:
My friend who was meant to receive the two older plants for his cabinet can't receive them quite yet, but i really need to open space for the new sprout, so another friend will be receiving the two older plants today at night and will put them in bigger pots with an organic mix to receive 12/12 outdoors.

UPDATE
News
I finally received my @Greenleaf Nutrients (MC and Cal-Mag Pro), oh yeah!
The two older plants have a new home. Now i just have the young seedlings, the basil, the chamomile, and an Auto AK spout in the tent.

Feeding
I plan to start using the MC. Will maintain the 0.7 EC I was working with and see what happens.

How the tent looks now

UPDATE
News
The Auto AK got transplanted last night so things look a bit different in the tent. Had to raise the light, so now it's at least at 34 inches from all plants.
The bag-seed plants will stay in the tent for one more week and will then depart to their future homes. Once they are gone, this journal will be paused until new bag-seeds are used.

Feeding
The two bag-seeds (older plants), and the basil and chamomile are getting MC + Cal-Mag at 0.83 EC, 5.8-5.9 pH.
