Oh Bro, considering the good general health of the leaves, these spots are very suggestive of droplet sunburn.

Could be dry areas in your root system if your using fabric planters.

It looks like my plant is dieing! Plants turning brown after intense watering period
Did I drown my plant? Stress it? I gave a lot of water in a short duration of time, and now 7 days later she is looking terrible! Read my diary on week 17 for more info!

Nitrogen toxicity? Or calmag deficiency.
Calmag added previous feeding 1 ml for 3L water. My plants just started to preflower and added 3L water for 3 plants 3ml grow, 2ml heaven, 3ml topmaxx, 3ml bloom That was my last schedule. I feed with every watering 2-3 times a week. Most damaged plant is Northern Lights Auto RQ

Brown spots on leaves. Can this be because of too high pH of the water (7.5)?

Spots on leaves
Anyone know what's causing this? Slight discoloration and rust spots, mainly on older leaves. It's not that bad but quite spread out. did spray with neem oil recently, so is it just burn spots or a nutrient problem?

What kind of deficiency is this or is it light burn? Can provide more pictures since they are in a sleep period now. It’s this plant, strawberry banana one and the purple queen.

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
