Well, i'm two weeks into 12/12 and everything has been going very well...one of my plants is about 3 inches taller than the others...3 days ago i noticed some leaf burn...so i raised it two inches...yesterday it appeared to worsen...raised it another 2 in. today...any suggestions? does it take a while for leaf burn to recover and does the burn make the plant more susceptible to easier burns in the future?
so today i check em out and they still look like they're being burnt...yet when i place my hand at the place of the canopy for about a minute it doesn't become hot...its definitely leaf burn...could it just be showing the effects of burns from the previous 2 days?
Can you supply photos mate as you might have nutrient burn and think it heat burn. Photos usually help solve the problem. I have had problems of late and the guys on here helped out a treat.
here are some photos...i'm beginning to think it may be a ph problem because three of my plants are very yellow...soil is happy frog from humbloldt...check em out...the one looks pretty sick...they've all filled in nicely but the leaves are mighty yellow and facing down...i've only fertilized them once in the last 3 wks and it was with a very light dose of liquid karma and bio-bloom by biobizz...any ideas...is it ph or a deficiency
also some extra info...my tap water has a ph of 7...my nute mix is about 5.8 which i use rarely (once every 2 weeks)...i've added bushmaster to the three that are now yellow when i come to think bout it...used it 2x a week for first two weeks of flowering to stunt stretching...prob. a ph problem although bushmaster also reads at about 5.9...plants were watered yesterday so i can't overwater to check the ph...any ideas?
became impatient...gave em some ph adjusted water at 7.5 with some superthrive to hopefully help with the stress...all in all the mix was 7.5...these problems seems identicle to the ones i had early in veg which was low ph...hope i made the right call and let u know if they shape up
it does have some potential...but the plants are honestly very ill looking...leaves around bud region all point down with yellow tip...large yellow leaves that curl all over the plants...all my leaves are also very yellow and i've used light fetilization...what could be the problem?
zandor recommended a good flush b/c the crisp leaves are a dead give away to toxic salt build up...will do...thanks
