Slow growth and yellow leaves

So I have two autos at week 4. (Rqs auto gorilla and Dreamberry) The first two weeks looked quite good. Then between the start of 3-4 showed very limited growth and the first two true leaves turned yellow, now I’m noticing the next set are doing the same. At first I thought it was a calmag issue and possibly nitrogen deficiency and immediately started adding it to my water which is ro, probably should have started that sooner. At day one of week 3 I started a half dose of roots uprising grow as a top dress. Now I feel like the top leaves are a bit dark leading me to think nitrogen toxicity, but with yellow leaves I’m at a loss. I started lst at week 3 so I could understand them being shorter, but around 4 inches is a bit ridiculous. I’m growing in ffof with nature’s living soil mixed into the bottom third of my 3 gal fabric pots. I water every 2-3 days as the soil is bone dry by then. I’ve been running at 75 degrees/ 55% rh. Not sure if my light could be a factor, Viparspectra va 1000, but I have an hlg 135 v2 arriving in two days. Any and all suggestions are welcome!

I thought I’d get at least one Bernie supporting basement dweller after mentioning Viparspectra. Where are you Bernie bro’s? Let me have it commies! Riu is well fortified with Che comrades. I’m all ears

Have you checked with a loupe closely for insects? Leaves have suspect markings....just a thought.

Using ffof in a tent, should that be a common threat?

They are ALWAYS a constant threat to cannabis growers.
Research thrips, mites, aphids, gnats, and a host of others....hoping it's not your issue, but most have a proactive outlook to the threat, as opposed to reacting after infestations.
Good luck

Take your political crap to the politics section or better yet, stick it up that hole in your backside where that tiny thing you call a brain resides.

Does look like critters are in there. And yes, commercial soils can have them. FF had a serious issue a few years back with mites.

The tips on the lowers are showing some burning. How often are you feeding watering?
