My first grow Zkittlez/Cocofresh

For week 2 I did couple of changes: Water change in order to add TPS Silica Lower the light to 16 inches / 30% light / I’m getting a PPFD of 300/400 Both genetics are wronging super fast, the only thing is the COCO FRESH when there is no light the leafs kind of go down, once they get light they go back up again, wondering is that’s how they are or if there is a problem, I will ask around here, if anyone knows why I will appreciate all the info. This week I should be able to switch the light from the G8600W to the G1000W, I’m moving the 8600 to a 4x4 with another genetic. I will also get the T7 AC humidifier and I will change also the in line fan to AC, I want to control everything with my phone (AC infinity app)
