Do these look healthy? Thoughts? I'm new to hydro/growingI have autos growing in a dwc system being fed half the regular amount of hydroguard, calmag, and grow/bloom. 1 plant is a week younger. The dark green plant looks like its leaves are clawing and has big brown spots on the leaves. The other has some brown dots and little yellow.

Calcium / PH issues? Did I take the correct steps?Am I on the right track to remedy my plant's issues? Seems like calcium deficiency to me. Soil test comes in at just under 6.5, my reservoir water going in is 7.3ph, in case its actually a lack of calcium and not the PH i've top dressed gypsum (and epsom salts).

It's my first time, and i think i have been watering it too much
I also fed it 2-0-0 npk water with 4ml per liter and I since learned it's not okay. Will it recover? Is this too little grow for day 4?

What kind of deficiency? What should I do? By the way, they're autos.What kind of deficiency do I have going on here?
I gave a good dose of calmag last night. The first signs were the dark spots on the leaves.
Been feeding ff bloom nutes every other day, 1/4 to 1/2 strength.
started from the bottom. Leaves turn yellow and then dry up.

What nutrient deficiency is this?What nutrient deficiency is this? Or is it nutrient burn? I'm watering with 5.5 PH using half strength Nutes, Root booster & Calmag. I don't think it relates to spiders mites since I can't see any with my 30x magnifier. Thank you so much in advance.

Nutrient lockout, ph imbalance or nutrient burn?Unfortunately I don't have a ph meter, so my best guess is one or more of these problems: nutrient lockout, ph imbalance or nutrient burn.
The first 3 photos are from an Auto Northern Light and the last 2 are from an Auto Jack Herer.
