They look pretty good to me. If macros are a problem try composting some eggshells; they take a real long time to break down but also keep working for a long time once they do. I toss them in my worm bin after nuking for a minute to kill off pathogens; veggie omelettes are my specialty.I'm building a new batch of soil and listing what I have added and what I still want to add.
I have a good feeling about the next mix.
I was using small amounts of lime when I re amended a soil and it caught up with me this grow. Unusual leaf discoloration. Light green patches on some fan leaves and lower fan leaves that appeared heat stressed with lifted corners that developed long after they were away from the lights. A clone I'm growing developed upper fan leave necrotic spots appearing to be a calcium deficiency.
I'm never 100% sure when it comes to diagnosing plants but I'm quite sure the lack of lime used when re amending caused a low soil PH. Adding 1 1/2 TBL of dolomite lime per gallon of soil about 6 weeks ago seems to have corrected the problem.
The 1st two pics show what I think is a calcium deficiency, the clones got hit the hardest, the seedlings only developed a random spot on a few leaves. I flipped to 12/12 on 1-1-20.
Happy Growing!

Multiple sources of macros spread the net wider: garden gypsum is good to add at recycles as well. Diversity is never a bad thing; it's better to give lots of different things in small amounts than to add a lot of one kind of input. Don't be afraid to up the dose a bit either. Have not had to give a soluble liquid cal/mag since adding gypsum along with D-lime. Whenever Im not sure what's the issue but I know something off adding more fresh ewc always seems to fix it.
