French cookie 3x3 grow.

I had a problem with the leaf twisting,so i flushed some water through the pots. I had come to the week where i was going to defoliate and train them,but now im a little unsure whether to go ahead as the stress from in imbalance in the root zone maybe a little too much stress together,also the plants seem to be getting wider rather than taller,the branches are thick and quite open already. I dont want them too big as i have to change the GSC plant into a bigger asap to go into flower With 2 underdawg kush in there at a week old it will get crammed. Im going to put them into flower at 2 weeks,because i read they streth alot,we will see how that goes. i will be netting the french cookies this week as i think they will need support. Given a topping at 4th node on one and 3rd on the other.Also i have increased light levels to 75% from the LED at 1 inches. Cutting have been taken from both french cookies,i have one very indica one ,dark wide leaves and chunky stem.The other being more delicate with leaves and stem being more delicate looking and slightly lighter green.I often find that the more sativa phenos are more powerful ,very much so with the more sativa side in the GG4 seeds i have tried,also being the lighter and later finishing ones, Lets see if it applies to this breed..
