miracle grow potting soil is evil. it's burning your plants, transplant ASAP and water with no nutrients for awhile.

Wait a minute... does that MG even have time release nutes? I have used MG soil before, it didn't have any time release and i had ZERO problems with it. I have read before and also from my experience, heat stress damage looks alot like nutrient burn, except it occurs only at the tops of the plants closest to the lamps.

bags feeds for 2 months

time release..its not good to start plants in here..only to move mature plants into here...peace
edit...its not the greatest shit it can grow weed..but be vary carful..i recomend using 100%perlite in buckets with a hole cut 2 in up from the bottem on 1 side of the bucket...this media offers a always netural ph...some people dont even check ph with this method...peace

After mixing fertilizer into the water, especially nitrogen, the solution's pH must be checked.

I say the plant in the picture may be suffering from heat stress, but that just my opinion. The reason i say this is because you have more then 1 plant and the rest are doing fine. Right? I think they were just recently transplanted into this soil. Right? Not really enough time to dissolve the time release caps. And you also mentioned that this one particular plant is under a larger bulb? Do you have a oscillating fan blowing between the lights and canopy? I really think it looks like heat stress, but like i said that just my opinion. Also if that MG has time release it will probably cause problems down the road. I would get those plants out of that shit ASAP, like everyone else suggested.

yes the rest are fine and i just transplanted them 2 or 3 days ago the fan i have doesnt oscillate so i have it blow at the stalks where in a spot where all the plants benifate from it...but i will locate some different soil and try again

imo i see those tips of biger fan leaves lower on the plant as why i call nute burn..i agree that the light may be to close...but the burning isn't just on the top growth but lower as well...peace

It's a combo of the three.light burn,MG soil,and perlite.You can get soil at wal-mart and perlite too.Besure that the perlite dosent have nutr in it too.Some MG's perlite has nutr in it.Get your soil and perlite and mix 40% perlte to the soil.Add one table spoon of dolilite lime to every one gal of soil mix it all together.Lime is a PH buffer,it will bring the soil to a neutral ph.Transplant and water with a PH of 6.4 up to 6.9 water for two waterings and then 1/4 strenght for the first two feeding and then move up the strenght.New no nutr soil and you will be good to go and your baby will love you back for it. PEACE
