Need to know more to help you hun..
soil brand..
nutes and how much/often
pH of water and nute solution
Sorry to be argumentative- but if it were the lights, it would start at the very top of the plant- not the sides/bottom....
That is getting bad real fast... the more info you can give us- the better we can help you... Start out by flushing the plant- UNLESS it is in soil with slow release nutes in it?
OK..
im using FFOF soil.. no perlite or anything. just FFOF..i had em in dixie cups for 2 weeks then transplanted them into the 5 gallon pots. ive given them like 3 feedings since 2 1/2 weeks.. its been 4 weeks today.. i used about 1 1/2 gallons total feeding all 12 plants. first 2 were 1/4 doses then upd it to almost full dose.. 2 of my plants are looking great. GREAT and Healthy..minor clawing from over watering i think but other than that. they are good looking. and theyve got same dose and water and everything..
the nutes im using is bio grow, bio weed,, ca+mg, from the general organics GO Box. was using bio root for the first 2 feedings.
The Temps are from 76-79...it got to 86 one time,, but only bcuz the duct came off from air cooled hood. thats what caused this all to start. although. 4 of my plants are not that heat burned but still have the defiencies.
when i water i usually give each plant around 1/4 of a gallon.. is this an ok amount..too much or too lil??i dont get really any runoff..i little.. but not much.. i didnt wanna overwater. but i think i have.. the ph i cant check bcuz i dont have tester im using TAP water..but im thinking of starting to use RO water..
