Okay, so my plant has yellowing on the older leaves and it's slowly working it's way up the plant. I've given it nutes, but it's still progressing upwards. Is it a N def. or could my PH be off? I don't have a way to test my PH. I ordered a moisture and PH tester online, wich should be here this Saturday. I'm thinking it's either N def. or is locking out nutes due to an off PH. What do you think?

1. You have heat stress if you look at pic 2 the leaves are folding up like tacos move the light up some.
2. Doesn't look like "N dif" you see the brown rust spot in pic 1 looks like cal-mag dif.
Get your self cal-mag other then that she looks good :clap:

Put some sort of direct airflow on the plant itself and you can achieve closer distances to the lights, gauge the heat by using the back of your hand over the top of the canopy of the plant.
