Question

[Tech]

is it from over heat ?

Few things look wrong there, whats your growing conditions? medium, temps day/night, nutes, ventilation, lighting and ph run off would help for a better answere.

Soil mix, Ill list the components later,
Temps 90(max)-65(min)
Nutes ( if i can remember thoroughly its (6%)calcium (4%)and nitrogen)
Ph around 7.5-7.7
Lightning 4x400w

Looks like nute problems to me especially the cupped leaves--soil contents very important to know in order to feed properly.

Why are you running your pH so high?

 

[Tech]

I guess its not very high, but high.
I heard abaove 8 is bad.. around 7'ish is good

High, I like my ph for my organic soil, around 5.8-6.2 yours imo is too high, and your day temp is too hot.

There looks like theres some phosphorus lock going on there which is caused by higher ph levels...

I like to keep my ph between 5.5 and 6.0......
