Power plant

Hi!!! So this plant has stretched a good 6-7 inches this week and has started to move to bud development. During the week I snipped off all the lower 4 nodes and branches except for the leaves. I noticed a little mold in the soil so I covered it in diatomaceous earth and let the soil dry an extra day. I also moved the fan to the bottom of the tent and pointed it up to circulate the air from the bottom and to help dry the top layer of soil faster. I also installed a fan to circulate air on the top of the colas so they don’t burn from the light but this fan will turn off with the lights and the bottom fan will stay on 24/7. It’s looking good any input helps.
