I am using GH Flora trio schedule at 1/2 tsp/gal and Hydroguard 1ml/gal
Germinated and transferred to rockwool on 4/20 so 6 days old
Moved the light up thinking it was too close.
Just changed water and nutrients this morning hoping something will get them looking healthier.
Your humidity could stand to be raised, especially at that this point in its life.
It does seem like it might have gotten little heat stress from the light maybe.
You definitely don’t want your temps reaching 87 degrees even if 78 is your average because your night time temps will lower your overall average, and it’s not so much the air temp that you want at 75- 78 degrees as much as the leaf temperature. If your air temps are 78 degrees but your lights are way too close to your plant then your temperatures will naturally be higher at the leaf than your air temps being recorded in your tent.
One last thing, your water level should be about an inch below your net pot and your water temps are best when they are below about 70 degrees. I always have enough air pumping into my water also that it looks like it’s at a “rolling boil” too.
