i too have some leafage having similar symptoms...
gonna watch this thread.

mine are outdoor, FF nutes, and a s*** load of rain....
feed once a week, watered when top couple inches were dry.
use well, not hard (17 ppm)
ph 6.6 out faucet.
6.5 last runoff check
lower sun leaves dying off.
sprayed for mites... bass turds. used FF dont bug me then iso/water.
my guess is 4 to 5 weeks to harvest.
hate when harvest draws near... i get so stressed lol
worry out deficiencies, disease, rot, LEO, and getting ripped off.
cant wait till its over so i can bake it and relax! lol
and they say gardening has a calming effect! lol
ok, back to me sunday morning bong.
ciao. :cool2:

Hello funmauiboy going by the information provided i'll have to say that you are Root bound ! You need to carefully remove outta there and grab a 5-6 gallon pot it should see you through safely ! A 3ft plant will eeasily become root bound in a 2 1/2 gall pot no worries ! Vermiculite i don't feel is neccersary as i've heard that it can be problamatic and you have perlite which will do the same job ...70% soil and 30% perlite will be fine ..Currently you have 50% soil which i think is also a part of the problem ! Once i have repotted i'd also knock my ppm back to 900-1100ppm to ensure that there is not a salts build up as well >>oohh and what the brand name of the general hydro nutes and do they contain trace elements Mg , iron , and boron ? This is my only my opinion on the matter at hand ! Feel free to wait for furtheer advice which is advised or jump in the deep end ! LOL ! Peace and take care !

What is the current Air Flow? (cfm etc.) i use A/C and a 6" can fan..zero air exchange with outside air
.....

DING

no CO2 coming in, give them some


Also, I think that plant has gotten too big for that container. I have had the same problem where the leaves start to brown the leaves, then eventually browns the tips and turns them upwards

good luck and report back
