please help my biggest plant has droopy leaves purple stems and i dont know if im overwatering or what if u can help thx and whats the best lighting scdule for regular plants i got from my stash it was on 16/8 to 12/12

#1 more light. https://www.rollitup.org/cfl-growing/41024-cfl-proximity-foliage.html
#2 less water
#3 more nitrogen+potassium?

Wait, are you in 12/12 now? That will induce flowering, do you want that?

i have 2 more 26 watt daylight 6500k cfls hanging still more light nitrogen + potassium what do u recommend and i burned leaves thats y the leaves at the top have a little brown area cuz i had sum lights that got to hot and burned it

i put it on 12/12 cux i thought it would mature faster what do u recommend for reggie bud or i guest kb i had it on 16/8 then changed to 12/12 is this bad

no i dont want it to flowery yet

and ive been giving it sun rays from a window then back in the grow room but man this is my first grow and i need sum help

Go back to 18/6 those plants need more light aswell they are very stretched you should invest in a 400w hps if you want nice buds on those plants

yes more light,,,,,,are u feeding any nutes at all,,,,,,whats there are flow like in that room,,,,they may need a fan,,,,18/6 for veg,,,,12/12 for flowering.

maybe think about abit of l.s.t to change the profile of the garden? https://www.rollitup.org/newbie-central/237035-guide-training-techniques-lst-sog.html

i have a fan but i only turn on every now and then cuz i have ac in my room and dont want it to get to cold cuz i like it to be cold in my room but its in my closet and i only use water n light no nutes at all i put the light back on 18/6 today will that effect the plant
