Hi there! Your feeding schedule seems to be correct. This looks like a LED-burn to me, those little dots appearing at the same position on different leaves also happened to me in the past, my light was too close to the plants, those dots/spots were the first signs to appear. What's your light distance? The hand-test is quite universal. Hope this helps, I'll be around, keep us up-to-date and happy growing!

It's not the temperatures. Have you measured your water EC/PPM? I mean, why are you using cal max? It's your water los on it? Anyway those spots are excess calcium burn; your leaves looks too dark green, like nitrogen toxicity. Stop feeding so early. There's no need for it, let the plant feed from the soil.
