Yes I fucked up once.
I added nutes a lil to early but stopped immediatetly.
Is that the reason of the messed up leaf? Also i have no idea what the ph levels are. *Kinda just rambling,
If you got an opinion. please share it
Same watering question. Go buy a ph test kit and run some water through your pot and find out the runoff ph. Don't feed any more for at LEAST a couple weeks. Also, are you attempting to grow cardboard next to it? Good luck!
