Delahaze screw up!

Fungus or N defenciency?

please take pics in white light only. right now it looks like bad heat damage along with some over fert.

I will do that. I try not to turn the lights off once they come on. I will get to them today. I appreciate the help!

These are about a week ago. Seems the new growth is ok...

that still looks like heat damage. has it been getting worse?

No but new leaf growth has yellow tips. Seems to be a bit of heat stress and mute defenciency

Delahaze has to be discarded. Super silver haze and liberty haze still strong
