Guys, thanks, but only the BAK has hit 5 nodes and it's in a larger (4.5") pot. I can't believe any of these would have exhausted the nutes in the soil yet - even without Doc's kit.
Here is an example from each of the three plants:
This is the BAK. Note both leaves in this pic:
The Tut and FP are both the same size and here's examples from each of them:
All environmentals are sound: Temps range from 75*-79* night/day, RH 50%-60% (a little low, maybe, but don't think it's the cause of the issue), only watering when pots are dry. Only the BAK has had any drenches, so far. Started with a transplant, water + 1/4 transplant, then a GE.
I did see that Duggan does not start GE until much later, which is a strategy I'll likely adopt, but I did want to give the Kush a boost early since it's supposed to be a heavy feeder and I'm anxious to get some clones out of her!
I will not be transplanting these to larger pots for quite some time, since they're going to be Bonsai mom's.
Small pots are not an issue for Bonsai's in soil, but perhaps I need a more traditional feeding routine for the Bonsai Mom's and the kit is better suited for the flowering plants? Again, I was just hoping to keep the Bonsai Mom's in some high brix soil, if at all possible.
Thanks for responses.
