Critical Orange Punch

This week i noticed the both COP#3 and #2 were kinda loose in the soil, To handle it I added some more soil and adjusted and lowered the fan speed. Two days after doing that I already could see some result, the stalk is getting stronger and thicker, sounds that it worked. I'm trying to decide what techniques should I try in this cycle, last cycle I topped and did some scrogging on the single plant I putted on this same setup. Wonder if i should try different trainings for each plant. i don't know yet, will do some research first.
