Indoor 4 Strains, 4 Breeders, 4 COBs RDWC & 1 Reservoir with MegaCrop

[Boradan]

yikes nasty surprize glad disaster was averted,ahh sure you were gonna paint the kitchen ceiling anyways
fantastic bit of growth last wee bit,as you say cant keep everybody happy all of the time,so its a happy medium for all 4.
good luck n keep er lit

I HATE painting (used to do it as a living), so a repaint will probably only happen about 1 day before I move out

I am actually really pleased with how the plants are right now considering the following:

1 plant (NL) LOVES nutrients and would probably take 30% more than it is currently getting without issues.
1 plant (DD) needs about 35% less feed than the NL.
2 plants (4AM and CBD) need about 50% of the feed that the NL does.
1 plant (CBD) is a Cal/Mag fiend.
My pH pen shit the bed a few weeks into the grow.
My ppm pen shit the bed a few weeks into the grow.
Water, water, everywhere, nor any drop to drink...

Day 36 Update:
(this brings the thread fully up to date)

Moving nicely along now.
4AM and CBD Auto have mostly gotten over their N Tox and CalMag issues and are starting to fill out nicely moe.
No sign of any pre-flowers for the ladies yet, so this is looking like an 80+ day grow.
The reservoir is now getting 1ml per litre of Remo Magnifical and I am then adding from a solution of MegaCrop until it hits about 550ppm total (including 200 ppm from the tap water).
This is dropping nicely by about 20ppm per day which I can live with as it seems to be keeping both the low and large eaters relatively happy.
Temperatures are running at:
Water: 21C
Air: 24.5C Day and 19C Night
Humidity: 60% - been a bit higher the last few days due to it raining. A lot.
I still haven't done much defoliation, but I may kick it into gear this week as a few of the plants are getting too bushy for leaf tucking to be effective any more.

Even with the differing growth rates, I have a relatively even canopy due to some well placed LST.
These ladies are all growing under a SINGLE 150W COB that has not been turned up over 75 watts until today. I will gradually start increasing it over the next few weeks as the plants move from veg to flower.
A few mornings ago, I woke up at Stupid O'Clock and discovered that I was running 18/6 instead of 20/4. That has now been sorted out.
I was planning on running these under 4 of the COBs, but I am now really leaning towards seeing what I can get from a single COB

Day 37 - time for some Defoliation:

Sweet Seeds Dark Devil:

SeedStockers Northern Lights:

Dinafem Dinamed CBD:

The 4AM has not been defoliated as it is still significantly behind these three.
Time to see those side-side branches get some light and boost their growth.

 

[Boradan]

The ladies are eating a LOT now with the ppm dropping 30-40 per day.
I just topped up the reservoir with pH'ed water and added Mega Crop to bring it up to 600ppm (EC 1.2)
pH is at 5.8 with the changes and I will keep a close eye on it.
The 3 that were defoliated didn't even seem to slow down with growth, so all is well with the world.

Day 42 Update
It has been a relatively straightforward week without any issues cropping up.
The ladies have recovered well from their defoliation and the 4AM is starting to catch up to the other 3 in size - although it is still some way off.

Currently running at:
pH 6.2
Humidity: 62%
Water temp: 20.5C
Air temp: 24.6C
ppm: 580

The COB is now at just shy of 100W and is doing a glorious job.
At this stage in my previous grow, I had been running 2 x 600W Viparspectras over the same area and the plants were around the same size.
The Vipars run at 260 wall Watts each, so I have the same growth with under 100Watts as I did with 520Watts previously. Pretty damned impressive.
When you take into account the fact that I have been gradually increasing the COB over the last 7 weeks, it has been using significantly less than 100W on average.

NORTHERN LIGHTS - SEEDSTOCKERS

Keeping a nice even canopy so far using LST.
The 4AM (front left) is smaller still than the others, but is hitting about the same canopy level.
Very pleased overall with this grow so far - especially using under 100W of COB

Day 45 Update
Full rez change yesterday. ppm increased to 700.
The 4 Assed Monkey is still having issues.
N Tox combined with Cal/Mag issues are not great in a system with 4 plants sharing the same res
This is not running down the Mephisto genetics in any way. It is simply an issue that can pop up when multiple breeder strains are sharing the same reservoir. Heck, it can even happen with 4 of the SAME strain if you get different phenotypes. I was just unlucky enough to pick a strain that is a lot more sensitive to nutes and COB lights than the other 3.

The rez was filled with the following:
60Litres Tap water - 210ppm (aerated for 2 days to help dissipate the chlorine)
Megacrop: 50g
Remo Magnifical: 20ml
Remo Astro Flower: 20ml
Atamai Ataclean: 30ml
Water Surfactant (whose name I can't remember and am too stoned to go upstairs to read it): 30ml
Total ppm: 700
pH 5.9

24 hours later and the readings are exactly the same at pH5.9 and ppm 700. Can't complain about that

The tent is getting full now with only 1 or 2 inches of space around the plants.
Time to stop doing new LST and let the growth go vertical.

@Boradan ,very nice job, with your plants, they look great to me.
I've only grown 4plants all autos with MegaCrop and SweetCandy, but my plants love it, along with some Recharge, but that's all I'm using from now on, it's good stuff.

Thanks
I got the MegaCrop on their 1kg freebie offer. Cost me $33 for shipping.
I believe they have a UK supplier now, so I will track that down and see if they also do the sweet Candy. I think my next grow will be done using only their products although I need to check and see if the Cal/Mag they do is also N heavy after seeing the issues with the 4AM I am growing

Some pictures:
Dark Devil
You can see the hint of purple starting on one of the stems. Not sure whether that is its colour starting, or some nutrient issue. Hopefully the former...

4 Assed Monkey
Still the runt of the litter, but coming along nicely.

Northern Lights
Still huuuuuge. Still no pistils. I keep getting flashbacks to my last grow where it turned out that one of my Autos was a Photo...

Dinamed CBD
Looking great. Seeing the start of some colour on this one too. Fingers crossed...

Full Tent
As you can see, almost every inch is taken up now - maybe an inch or 2 at the sides, but not much.
The canopy is still nice and level.

I think I need to do some more defoliation...

@Boradan , Your plants are beautiful and healthy looking, great colors,
That's all I'm using from now on is MegaCrop and SweetCandy, And by the time I add 1teaspoon , 5-6grams, a gallon of water ofMegaCrop and a quarter teaspoon of SweetCandy my tap water comes out a perfect 6.2-6.4 ph. Man that's easy enough, with my tap water, I don't have any cal-mag problems. But I do use cal-mag, the first couple of weeks though.
I don't know enough about MegaCrop, to know if I need to cut back in flower, But I'm going to cut back about half a teaspoon, anyway , until I get used to growing with it.
But my plants sure love it.
Ever now and then I get a purple looking stem, but seems its in cooler weather when I get them. Or either a strain that turns colors.
Anyway ,sorry for the ramblings, But your plants look great,man.
Ps, I forgot, if they were mine I would take a few of those big fans, or tuck them.
I know that's a controversial topic, but I'll take leaves of in a minute, especially the inside ones.
