Grow Mediums New Grower using Hempy Buckets and LED with Canna nutes.

***Update*** Day 18

Hi Guys,

As I mentioned before I am getting a little yellowing from the first set of single finger leaves (after the cotyledon leaves).
After doing some web-research this seems like it is pretty normal and is just what happens when those leaves start sending their stored energy up the plant for the new multi-fingered leaves to use. So no worries there.

But I did notice some spotting, and some pretty noticeable yellowing, on some of the three fingered leaves of the A. Critical Jacks, and the two remaining Think Differents have both been a little slow in comparison to the A. Blueberries and A. Extremes (all of which look pretty fantastic).

I guess this is just what you have to expect when dealing with five totally different strains at once (probably not the best first time hydro-grower move).

I think the low Ph I used for germination (5.2) was not cool for the TDs, but the rest of the babies seemed to love it. I bumped it up to 5.5 after the first few days, and now I am riding right between 5.5 and 5.6.

I am also thinking that even a slightly less than half recommended minimum strength mix might have still been too much nutes for the Autos, so the next watering (probably tomorrow, they don't look like they need a watering today and I don't want to fall into the common newbie over-watering trap) I will hit them with Ph adjusted plain water (maybe just add the beneficials and a quarter strength Rhizotonic mix). I'll try to keep the EC around 0.1~0.2 after Ph adjustment.

Any ideas or advce would be appreciated.

I can't post pics of the yellowing/spotting for about 8~10hours from now as the room needs to be kept off limits to any door opening during most of the day (one of the main reasons I am using Hempy Buckets and automating the CO2 system).

As soon as I can get some I will post pics of what they all look like.

Cheers,
Betelnut

Hi Guys,

Sorry for not posting pics of the yellowing yet.

I have had a busy few days and other than basic maintenance and one close inspection of all the babies I have not had much time "In The Room".

Things are looking better (I think there was just a touch of nute burn, but not much), so I am not sweating too hard. But I still plan on taking some pics (most likely tonight) and putting them up so I can get more eyes on them.

Cheers,
Betelnut

***Update*** Day 29

Hi Guys,

I finally had some time to take a few pics, but I was in a rush and honestly they don’t show what I am worried about as much as I had hoped they would. I might be able to get some better pics this evening.

If I can I will post them ASAP.

In the meantime here are the shots I took last night:




What I am seeing is great looking upper growth with horrible yellowing on some of the lower leaves.

Temp is at 29c (84.2f) during lights on and humidity is always around 55%.

I am starting to think my fears of "newbie over watering" and nute-burn were the exact opposite of the problem, and that I need to bump up the EC and watering schedule.

Last watering was a Ph balanced flush of pure water (Ph 5.7), but starting tonight I am going to head right back to EC 5.0 (ish) and head up from there. By the end of the week I am thinking of aiming for around 1.0 EC.

I could really use some more eyes on this, and I am wondering if I should start a new thread or something in order to get more advice…

Cheers,
Betelnut

hi bud ... you could use some help & as your set up is more kind of coco / hempy it may be an idea to move you over to the coco section ?.

I would guess its over or under feeding / watering ,maybe ph out as well ? I dont grow coco /hempy so cant advise much more than that but will ask a coco mod to look in on your grow :Sharing One:

Hi DWCocha,

Thanks for taking the time to look over my grow!

I don't use coco, my mix is 3:1 pearlite/vermiculite. Basically the original Hempy Bucket mix.
I have come to the (tentative) conclusion that it is an under watering/under-feeding problem.

So many posts for new growers warn about over watering, and so many posts warn about over feeding Autos, that I was halving the manufacturer's recommended doses and then watering as little as I could get away with before the leaves began to droop.

I think worrying too much about "Newbie Mistakes" is its own "Newbie Mistake".

Tonight I watered with an EC 0.8, Ph 5.8 mix with added Cal-mag+, Silica-blast, beneficials (bacteria and fungi from Advanced Nutrients), and Rhizotonic.
I also mixed up a weak Cal-Mag+ and Rhizotonic foliar spray for my partner to spray on the babies twice tomorrow (morning and noon).

I think once they start actually getting fed properly the yellowing should get way better.

Of course if any more experienced growers have other ideas or advice it would be super appreciated!

Cheers,
Betelnut

I used Hempy buckets with straight perlite a few years back with good success and is how i learned to go from soil to hydro and really enjoyed it...

With that said i think what you have planned going forward sounds like a real good plan. i saw it ussually took about 10 days for the roots to hit the 3in rez in the bottom from transplanting a rooted clone. from there i would always use the lift method of checking for water..pick it up after a full watering then ckeck it daily till you notice its light and getting dry then water again untill you figure out how often to water it and avoid the underwatering.

as far as overwatering...unless the vermicuilte holds alot more water than i would think ( never used with perlite alone) you shouldnt be able to really overwater much at all...

I had some similar issues here recently as you are with the yellowing in the middle leaves and some lower but not the top and it turned out to be calmag defcenciy and was corrected simpy by uping the calmag a bit.

none the less thats just my uneducated tid bit for ya

Hey!
All else considered everything looks great! You are in good hands now so I'm sure we'll get the yellowing under control.
If your cameras has a white balance control you can use a pice of something white to set it so it takes out the red color. Put the white something under the light, aim camera and tell it to adjust. Works on my Nikon SLRs.

Hi Betelnut- The color of the LEDS messes with diagnostics, so at the next lights-out, take a round of pics with the flash on, and some ambient lighting,... From where it's occurring (lower down, older leaves) and the pattern of yellowing, I think it's Mg deficiency; get a Ca-Mg dedicated supplement in there, and that should do it!
>> Yeah, auto's are variably sensitive to nutrient input, especially early on, but gradual ramping up of conc. as they get older/bigger is the best way to get them onto a near-to-full strength nute' regime; of course, this depends greatly on the product itself, how conc. it is,... mild stuff that has low N-P-K numbers is faster to ramp up, unlike something that's, say, 16-16-16, which warrants more caution! Frequency of the fertilizing also dictates how conc. you should apply nutes,... You're balancing and changing all the time, as the plants get bigger, and draw more in, and specific needs change too, ....so be careful, and think about how much you're put in, and what kind of draw/demand the plants are exerting on the supply...
