Look like Zinc and Calcium deficiency? Watering with 5.8/5.9pH, 2.06 EC (Runoff 5.8pH, 0.78 EC) Few leaves had small nutrient burn on the tips earlier this week. Nutrient burn appears to have tapered off.

Hey guys! Hope everything's going well. I have some burns on the leaves of just one plant, I gave it bio grow and top max biobizz. Humidity is at 50% and temperature is 27/30 °C unfortunately. I think it might be due to the lights being too close, but I wanted your opinion. Thanks a lot!

Why are there soon many brown spots all of a sudden in WK 7?
I'm entering Wk 7 and the same lady is hurting again. She's been feeding heavy for last few weeks and doing great. So, I gave a light water/microbes dose w/can and Epson. Now I think its potassium or something else entirely... Brown spotting, yellow, crispy? Thoughts?

I believe I have a phosphorus deficiency from lack of watering/early pH issues. I also have curly/dented leaves that can be seen in the close ups. Does this seem like a phosphorus deficiency or what else may it be?

Day 4, after emerging. Is this coloration on the cotyledons okay?
Humidity is 55 - 70, temp is around 20-24c, 50w full spec led 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?

Rusty spots mid-top of plants. A couple on each plant. Thoughts?
(Check diary for more details) Thinking calcium deficiency, also maybe magnesium deficiency on a few low yellowed leaves. Thinking it could be nutrient lockout? Feeding them 6.25 pH always. Gonna try 7.0 once and 6.5 for awhile. Thoughts anyone? Im still fairly new and learning
