Some sort of deficiency?

Hey guys, this is my Gorilla Glue autoflower a couple weeks into flower. The past couple days I’ve noticed some changes in the coloring of the leaves. I started my first feeding last week with Foxfarm Big Bloom and Grow Big about 1/3 of the normal dosage. I was thinking spider mites but I’ve throughly looked through the leaves with a loupe and couldn’t find a single mite, larve, or webbing of any kind. They also get a been treatment about once a week so I’m skeptical of that. I’m running on 300 watt LEDs. My soil is a 70% FFOF and 30% perlite grown in 3 gallon pots. Run off Ph is about 6.7. 18/6 light cycle watered about twice a week until minimal run off. Any ideas? It should be noted the pics were taken about an hour before lights out, so I’m sure that’s adding to the droop. They haven’t been like that the past couple days.

Do they get any Cal/Mag?

They haven’t gotten any yet. I’m going to grab some today. I’ve been using just dechlorinated rap so I thought I might be able to get away it

Recommend it. My source water has Ca / Mg in it as well but I'll still throw 7.5 ml/imp. gallon at each watering.

I have used the Botanicare Cal/Mag and Remo MagNiFiCal supplements at the recommended dosage on their bottles and they work well. A good number of the Cal/Mag products also have low levels of N which the plants need - even late in FLOWER. They get no more Cal/Mag after the end of Week 7.

Just let 'em gobble up all the stored nutes for the final 14 days before we chop.

Actually on my way to get some now. None of the stores in the area had stock yesterday but I got lucky today.
