Spraying the leaves
ZigkGrowstarted grow question 4y ago
While I was checking my plant I saw these “black stains” like the plant is “half-bitten/scorched”.Is it possible to burn my leaves and create this effect after spraying them with nutes. Blacks spots were created today after I sprayed them and there were drops on leaves for hours

Foliar Spraying while the lights are on make the drops as magnifiers and burn the plant. Spray while the lamp is off. Stomata on the leaves take 15-20mins to close after the lamp is turned off
,Cheers

nutrient solution on leaves can cause lots of weird effects. Even plain water can create a magnifying glass effect cause burnt spots on your leaves. Are you using calmag? I see what looks like the beginnings of a mag def. Happy growing.

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

Yellow Spots on LeafesSome leaves have developed yellow / light spots. I also have thrips in my tent, but I doubt they are the cause of these signs because they have been there for a year, and I have always been able to keep them under control and the spots they cause look diffrently. Ty for advise.

Are (constantly) high daytime temperatures a huge problem in flower?My day temperature since turing my light up to max during flower are reaching 29-30c | 84.2 - 86f, while the daytime RH is at roughly 40% - 50%.
Is the high temperature something to be concerned about?

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

Leaves turning yellow and dyingI 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?

I wanted to ask if you think this plant has mold or if it's just a major deficiency due to a blockage. I have an indoor plant next door with some plants growing with dark spots, it's in my previous question. Sorry for giving more information, I don't know what would help.
