Rusty brown spotting on upper fan leaves, too much Tiger Bloom or deficiency?
puppetmaster77started grow question 5y ago
Hindu auto, week 11 started seeing rusty brown spotting on upper fan leaves. At this point I was only using tap water and 4 tsp/gal of tiger bloom. That is aggressive so I backed off to 1.5 tsp. I watered with cal mag 1 tsp just in case it was deficient. Ideas? Buds seem ok.

I wanted to say itโs calcium but when the leaves turn like that itโs too much sauce, itโs nuts burn for sure, ease up on those nutes! Looks good though!

Looks like you have a phosphorus issue. I would check your ph. Phosphorus availability decreased with increase in pH.

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

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.
