Help! Leaves burnt spots!

Hi all! I have a 60*60 grow tent with 600w light LED. Temperature is 27degrees Celsius and humidity 70%. The leaves seems to dry out and burn… I have grown before in the same way and had the exact same problem! I can’t understand what’s wrong with them! Please need help!

It looks like splash from nutrient mix or maybe misting that has caused burning from water droplets. Is that possible?


I would think about transplanting into a 5-gallon pot you could also be getting root bound.


I don’t think it can root bond because I never transplant it but I grow in the same pot from the seed. Also don’t think it’s a splash because new spots keep appearing.

If possible fill out the support ticket will get you a wide range of support. May I ask what size pot you’re using?

What soil are you growing in ? Ph and ppm from runoff? Filling out a support ticket will help the most

Strain; Type, Bag seed, or NA

Soil in pots, Hydroponic, or Coco?
System type?

PH of runoff or solution in reservoir?

What is strength of nutrient mix? EC, or TDS
