You for sure need to take a little advice. Don't ask for help and not listen. I get its your first grow, you're excited, and want to figure everything out on your own, but listening to experienced growers is whats going to really help you learn how to "tinker" with your plants. Mainlining is when you strip bottom nodes and pinch or top the top node, continuing this so the 2 becomes 4 becomes 8 etc. You do not need to strip the bottom leaves, only the bottom nodes. If you're defoliating for mold or light penetration, remove leaves so at most only 50% of the light is shining through and hitting the soil. If even then youre still scared of mold or fungus, get a stronger exhaust fan, or get one period if you dont! Leaves aren't there to only grab light, leaves also store the plant's energy, so essentially every leaf you pull off, you are also stealing energy from the plant. Look at all the open space in your pot not being taken up by any leafs! Thats all photometric energy being wasted! It seems your ph and feeding is back on track (as in no burns or deficiencies), so if you leave some more leaves on, I think it will recover fine. If I come back in 2 weeks to some more photos of a plant that should be on the Naked and Afraid season finale, Ive lost hope for you HAHA! Good luck! I hope for the best for you!
