Super buff cherry Gelato grown with 20% Bruh science.
My super buff cherry. Almost time to shock closed those stomata using hormone ABA(Asbisic Acid) inducing abiotic stress, simultaneously using light signals to increase terpene/flavinoid production while having no Pr/Prf conversion to release VOC via shocked closed stomata.

Probable phosphorus deficiency?
What is happening? It's getting worse. Inert soil, just applying Remo nutrients (all of them). I put a layer of living soil on top, but it doesn't seem to have any effect.PH ok, other plants consume the same water without problems. Very hot here, 35°C/95°F

Leaves turning yellow and dying
I have a plant that gets a lot of rust spots, even though I give it CalMag once a week. That plant also started getting a handful of leaves that turn yellow and fall off. Is there a nutrient I'm missing in my regiment? Should I do CalMag every watering for the rust spots?

First time DWC, day 70, 3 weeks in flower. Nasty rusty spots appear on lower leaves. Is this CalMag or else? Please help understand and fix, thank you :)
I'm using TA Tripart, current EC is 1.6 - ph 5.5-6.5. Everything was smooth until week 10. Two weeks ago I started adding Plagron Power Buds and Green Sensation. Yesterday added CalMag to see if it helps, but it doesnt seem to... She drinks a lot, ph mostly goes down, EC static

Are those nutrient defficiencies? Which ones?
A plant had interveinal chlorosis on new leaves and then proceeded to show brown patches between veins on middle leaves. Another has coppery brown spots on leaf edges on the middle of the plant. Both were rootbound in living soil (peat/perlite/hummus + ammendments).

Ph value is decreasing despite BioBizzUp
I don´t get it I´m trying to increase the Ph value but it is permanently falling again to a value of 4,2. Any idea what could be the reason why my Ph adjustments (BioUp) are not taking effect in the soil. Additional question for SD: What to do with the brown leafes? Remove them?

LSD Auto BarneysFarm is showing nutrient deficiency. I need some help to get this girl unstressed.
I'm using BioBizz LightMix with the BioTabs Starter Kit in 25L pots (prepared the medium from the beginning with 3 biotabs). I have three girls where 2 of them are running healthy, only the LSD Auto is making trouble. How can I fix the problem which you can see on the image?

greyish leaftips and dieing branches after topping
the highest branches died after topping. It looks to me like they had the same symptoms like some new upper branches are developing now. It looks very dark & feels soft Temps were 17-19°C & Humidity was 90%+ Water should be PH5.9, think ph reader might be wrong and ph is too low?
