I have 2 ww fem autoflowers first in mg organic (I know not good) mixed with perlite using dr earth dry amendments. Temps stay around 80 humidity between 50 and 60 percent. Its 32 days old and new growth is turning yellow. The second is in soil with nothing in it mixed with compost and perlite also using dr earth. Same temp and humidity. It is 16 days old and I believe this one has a ph issue. Hopefully someone can verify that for me. I tried flushing 3 days ago but hasn't changed.
Help with deficiency

First two pics look pretty overfed; back off on the nutrients. Second two pics.... that one looks ok. If it doesnt get any worse, I would just stick to what your doing. Make sure you are letting the pots get nice and dry before watering again. Overwatering looks like all sorts of different issues. Autos are lite feeders. I switched from autos to photos this grow and everything went deficient because i was so used to growing lite feeding autos.
I did spray because I thought it was a fungus problem so I sprayed with neem oil. The first 2 are the ones I think is a ph problem. The leaves are hard.
I saw stealth grows on YouTube use 2 Tbls per gallon of dry amendments dr earth. Thats what I did. Im in 3 gallon pots and I mixed 6 Tbls into the original soil. No nutes added after. It started good than almost over night it went south.
These are my second and third grows so I'm just starting out. 1st one I thought the mg organic soil would feed for 3 weeks and the plant only got about 4 inches tall in 4 weeks and than got eaten when I took outside for a little. Trying to absorb as much info as possible. Thanks for any help

If you have the means to check your pH, I would encourage you to do that. The contorted / twisted leaves, in all your pics would suggest pH.
Thanks I do have a ph pen for adding water but have read that testing runoff in soil gives false readings. Not sure if that's true or not. I've been watering anywhere from 5.8 to 6.5ph. Did see soil should be 6 to 7? I seem to see conflicting things about ph in soil. Some people say being consistent in soil is more important than what the ph actually is. Idk. Now I'm shooting for 6.5 every time

You are correct, I would avoid checking my run off pH, but knowing your soil pH would be useful. If you are indeed in soil, 6.5 pH is what you're looking for. 5.8 pH is for coco and other hydro methods.
Would you suggest flushing that first one more? Not sure exactly whats going on with that ph. The only thing is does that get rid of the dry amendments and if it does do i need to add more? These are the things that mess me up. It was doing well and now seems stunted and leaves are dark green and crisp

I am not a proponent of flushing to fix a problem, largely because it doesn't. If you have dry amendments in your soil, a flush isn't going to remove them per se...it will help leach out some of the nutrient, but it most likely won't solve anything. If it were me, I'd simply give them pH'd water, when they need it and stop any further nutrients until they grow past what you've already given them. Be patient, it may take some time.

Agreed.
