I feed them grow big last nite for lush vegative growth and there under 600 watt metal halide temp ranges from 73 to 76 there is proper ventilation if anyone can please help out a brotha

What is the Ph of the run off water? It does look like over watering to me, but with out some more info it makes it hard to trouble shoot.

I didn't check the run off since last nite the ph was at 6.5 when I put it in I would have to see when I water again I am using fox farms nutes

I think you splashed nute water on the leaf how does the rest of the plant look we need pics of the rest of the plant.

drop that ph to 6.3 on the next watering nutes should be at less then quarter strength

Definitely doesn't look like your typical nutrient burn.

Here some better pics of themView attachment 2420824View attachment 2420827 and with grow big the ph was 6.5
