Yeah, looks like potassium deficiency, swapping to bloom nutes should sort that out

Why do I have brown/black spots on my OG leaves?Bare with me please. I purchased "aPotforaPot" kind of on a whim late one night. I planted 3 weeks ago yesterday and have been feeding exclusively water with PH ~5.5. Just received Cal-Mag in the mail and plan to use on the next watering. I'm starting to notice spots on OG leaves

Mid Flower, Yellow, burnt leavesWhat could be happening to this plant? Could it be root rot or overwatering ? its in middle flower, with good ph and organic nutrients from top crop, 26°C and 200W led cob. This are the older leafs, but the rest of the plant seems fine. this week I increased the PK levels.

Brown spot on leave. 6 weeks into flowering. -Temp 27'C day 25'C night- HD 65% day 75% night . Soil PH 6.5-7.00. Water always at 6.5-6.8ph.I just flush it 4 days ago because I think it got calmag lockout since I always give them around 5ml of calmag every watering. I only water when 2inch top soil dry with 1.5L of ph balance water. Not a fungus or anything that grow because It cannot be rub or remove from outside.

Dark dots in leaves. Lamp burns?I saw this dark dots in leaves but only she has it. She was exactly under spider-farmer sf1000 at 30 cm. Now I moved to other softer light at 40 cm. What do you think? Lamp burns? They're dry and curl up. Some images are edited for better appreciation but you have also originals.

Brown dark spots on fan leafAny clue what this is? It only appeared on 1 of the plants and only on 1 of the fan leaves. The brown color has kind of a metallic shine to it. My guess is that it’s a Cal. def. I also suspect it might be a Phosphorus def. as the plants turned dark green the last few days.

Deficiencies? Brown spots, yellowing and purple stemsWhat is this deficiency or maybe toxicity and whats the solution? She is fed with biobizz chart instructions but with every other watering. She is big so I'm guessing I should water with nutes every time? She showed this first week into flowering.
