Needs more Cowbell... JK... Im going to have to say ph lockout. @Renfro can prob attest to this. Get a good soil prob and see what it actually is. I did slurry tests, runoff, etc. but did not know my true PH until I got a good probe. Apera, Hanna make good ones. They are not cheap, but it literally saved this crop we have going now. I was racking my brain, but not throwing stuff at it to try and figure out what was going on... got the probe in, and poked the soil.... 5.1 PH even though we were feeding in at ~7.25. We had to make an extreme move and mix at 10.5-11.5 to get it to stabilize at the mid 6's. True story. But then again, there's a lot I don't know about your grow. Temps, RH, airflow, etc.

I'm running around 76 lights on and about 60 rh after watering and about 45 once everything is dry about three days later. I run a 4" fan in and out set on a 15 min interval on and off. Using 1 gallon fabric and just finished conquering a thrip problem. Plants are looking good but now noticing a def

Never had thrips, so I can't say if they are in recovery or still have a problem. But really, PH is something you really need to truly know what it is before you do anything else.

To be honest I bought a liquid ph meter first and bought a 25 buck amazon ph pen and both test the same level. Now I’ve never tested my run off and I think I will tonight to see but haven’t changed anything since last grow other then going to a Nute/no nute diet. Last crop fed almost 100% strength nutes every feeding and had a wicked harvest. I thought I would try a three stage feed on this crop and as of tonight I’m ditching that bullshit and putting these bitches on steroids. I was going about 400-500 ppm on nutes but went 800 ppm tonight. See what happens.

Let er' rip!.. but just remember, no matter how much you feed them, they will not take up those nutes if your PH is out of range.

Microbes regulate the ph right at the root surface. The rhizosphere.
Mother nature doesnt go around and check the ph of her soil.

I’m trying granular Mykro during transplant and Great White while watering this time. Hope it helps and isn’t just hype

Plants dont eat without microbes. They can absorb the water soluble nutes we feed them but anything organic they need microbes to break it down and feed the plant.

Try 1/16 tsp of great white per gal doesnt have to be a full 1/16 just once a week. All you need to use is enough that you know you have some in there working for you.

Gw isnt my first choice I like the Raw brand bloom use it in veg and bloom their veg microbes are almost the same as the bloom and no need to buy two products and have them both open laying around.

A little humic acid will help your grow as well. Humic acid and microbes are like burger and fries. They just go together.

and a kelp product just about every rooting product out there has kelp in it. Stop using kelp after week two of flower.

Just to embarrass myself, I will guess early overwatering (lower leaves look a bit swollen) that led to some yellowing, which then prompted a bump up in nutrients (the green line down the middle in some of the leaves). Next up, I would look out for small spots forming saying they are getting too much food.
