it looks like some kind of ph or nitro burn...i would check the ph run off an flush the roots out with phed water for a couple day then give a half feeding for the next 2 feeding...peace

i havent used neuts yet water is ph 6.5 to 6.8 runnoff is sometimes 6.4

what kind of soil..peace

mericle grow potting soil

I second nute burn

i only ever gave them ph adjusted water

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

yep nitro burn..sorry buddy your another casulty of the mg slow release nute soil..personally i would transplant into some 100%perlite bucket..an rinse out the roots of the plants for 1 week..then feed at half strenth next 2 feeding after that ..peace

shit...i cant find any other soil if i flush the piss out of it you think it will work not much selection around here in winter you know

you cant find perlite?

all the garden centers close for the winter here the ones that stay open sell useless things like sprinklers and stuff where else can i get it

home depot ,lowes, walmart....

shit...i did not know that many thanks

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.

thats where the damage is but it says on the bags feeds for 2 months but that plant is under the biggest bulb i have and its a different color spectrum

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

any brand recommendations

uumm..i just get the big green bag for 17bucks..its 3.5 cubic feet worth....sssooo its alot...lol

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