SOMEONE HELP ME < MARIJUANA PROBLEMS I NEED HELP FROM A EXPERT ON MARIJUANA GROWING ,


WHAT IS HAPPENING WITH THEM ?
i just putted them on flowering one week ago , all the vegetative i didnt had any problem

Overnuted and/or orverwatered. I assume you won't have a chance to determine the ph of you medium?

But this only happened after i started the flowering ... you mean if i have something to measure my ph ? i have a electronic ph measure , and every time i feed my plant i get close to 6,5 on the water ph

how big is that pot?

its like 45 cm , why?

Just a few leaves on the bottom? If so, don't worry about it too much unless it starts progressing upward. Those leaves are shaded. Shaded leaves aren't of much use to the plant, so it actually starts pulling nutrients out of them to fuel parts of the plant that have light.

pot looked small in first pic. it's okay.............
