What did you change?

What did you change?

I didnt change anything . Just the amount of red, black and green nutrient in the floragrow nutrient set.

Looks like a massacre, I'd say mass poisoning.

Edit: If you just changed the lights maye you are cooking them.

 

[Go go n chill]

Light is toooo close

Obvious heat stress

I would say your temps are around 30 degrees C... You can tell that its heat stress as the leaves are curling inwards and up. Immediately increase fans, lower light intensity, or just vent out the room

I'd hack off the nutes a little too. Have they shot up in height and are now closer to the lights?

The light is pretty far away . It was atleast 3-4 feet from the light to my plants.. temp is around 24-26 with A/C on . I just reduce the light to 750w.. damn it hurts watching them suffer
