Leaves dying in veg help

[Soyface]

I've been growing for 5 years and growing organic in Build-A-Soil for my third grow so I'm not a wizard but I can offer an opinion and you are asking for them.

Looking at your pics I think your garden looks righteous. Canopy filling the space. Yahoo! Trunk looks thick like shes been doing some serious vegging. It looks like your getting good results from your lighting and environment.

In this pic it looks like the pot is too small to contain an expanding root ball for a plant that big IMHO. The leaves look a little light green. I imagine roots are quickly filling up (within a couple weeks of transplant) and pulling all the Nutes out of a pot that size and they have 2 or 3 months to go in flower. Once the plant feels the squeeze on nutes or water she's gonna sacrifice leaves to save the flowers.

I think your suffering from your own success. You started with a puppy and now you have a Great Dane to take care of. Can't really see but it looks like the plants are maybe 3 feet tall and 3 feet wide. They'll probably grow another 2 feet in stretch. I think they're just demanding more food and water than those pots can provide. I think you should transplant into 15 gallon pots now before you flip, or at least do one of them to see if it helps for future grows. Examine the roots to see if they are circling or bunching up in the newest transplant soil when you have it out of the pot.

The dynamics of watering change as plants get big. A schedule that worked early won't later. Perhaps someone with experience growing in coco can offer you tips on watering big plants in coco during flower if your unsure. I've read that you need to water often and thoroughly. And you might check with the company that made the soil mix. They might have guides for their products on their web site. My advice on watering is, when you decide to water your plants, take an hour to water slowly so all the soil is wet to the bottom of the pot. Don't just moisten the top. Also, I've seen a few grow diary's on here from coco users who use drip watering systems to keep up with the needs of their plants.

I've never grown in this medium so take the above with a grain of salt. I'm offering my take on it but I'm just looking at pictures and trying to relate. I wish you success.

Thanks my dude and yeah they've been vegging for a while. I've had them in these pots for just about 5 weeks. I honestly don't know how full of roots they must be. When i first transplanted they grew really nice in the first 3 weeks and have now slowed down. They went from a 2 gallon pot and so to me it seemed like they would still have nutes by now since i tripled their pots size but maybe they did spread their roots faster than i expected.

The bigger ones are kind of unruly, they are smaller than they look though. They measure around 27 inches tall and maybe 28-29 inches long and maybe 17sh inches wide. I've trained them in a rectangular form to be able to fit all of them in there, i'm growing in a 5x5. I don't know if i could transplant them again, i'm running on a budget. And i also lack the desirable space to remove them from their pots right now.:/
Do you think i could just top dress em more frequently and do more compost teas?

I am still learning how to water them but seems like most except one of the big ones are happy with their waterings. That one has had droppy top leaves for about a week and a half. But the others are all still praying or mostly praying. I have done the slowly watering method mainly because if i don't water pours out the sides and my saucers aren't big enough to catch most of it. I don't water all the time all the way to bottom because i also lack the space to keep a dedicated aerated water tank so i'm sometimes just giving them a liter or so each of some left over water that i have. Usually they dry out their pots in 3-5 days when i water all the way through.

Temps are too low. They needed to come up to 78f-82f. Myself, I like it more towards 82f. 74f at lights out. They wont use nutrients like they should at such low temps, and you risk lock out, and ph problems. Look into Gaia Green fertilizer. Follow the directions.
At the least though, Id try and get the temps up.

Oh man my electric bill would be horrendous if i tried tto raise it and maintain it that high. Temperatures go down to the 50s everynight here. I just now got a dehumifier and i'm hoping that will do a good enough job at raising the temps lul. Humidity has risen to over 85% in my grow tent after a watering during lights off.

Oh, yeah. Now that I see the whole plant in the pictures, that should work. That's some pretty thick jungle in there.

I agree with @Budtirement that your pot looks a bit small. Usually the pots are taller than they are wide, to give the roots space

But also, I think you just have a lot of leaves, and some at the bottom get less light and are going to die, slowly. It's important to remove the yellowing leaves so your plant doesn't keep putting energy into them - you want them to focus on the good leaves and eventually buds!

It is pretty thick, i've been going off the advice i first got to just let them bush out until the flowering cycle and only remove the completely dead stuff. I don't know if it was the best thing to do since it feels like a lot of energy is going to waste keeping all of that growth going. I do remove dying stuff now though.

Yeah i got these pots on the advice of 420 scene on one of his videos, he talked about how it was good to have these to save vertical space for the stretching period. So far i think they're okay but it is kind of funny that my 2 gallon pots are almost as tall as these.

And i do have to remove a lot of dead and dying stuff almost everyday but it just seems to never end! I've been tempted to defoliate them of all the bottom growth for a while but i'm too afraid of all the stress it would cause to them.
