Spraying the leaves
ZigkGrowstarted grow question 4 years 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

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.

Ph value is decreasing despite BioBizzUpI 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.

4 times same genetic but one has hanging leavesThe top right plant´s leaves are hanging down since ~10 days. Don´t think it´s because of over-/underwatering, since I water & feed every plant the same and the others are doing great. Was it maybe too stressfull to set the LED from 160W to 240W on 35cm distance when going 12/12?

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?

Does anyone know what’s going on here?Hey I have the following problem: A week ago, I bought some cuttings from a seller, but they turned out to be infested with thrips. To tackle this, I used yellow sticky traps and watered with nematodes. I also sprayed BAC Plant Vitality Plus on the leaves.

Help, what are those weird yellow spots in late veg?Hello everybody, I've checked in on my plant after I was away from home for 2 day. Now I come back to see these ugly yellow spots? During day 23°C / 55% humid. During night 18°C / 50% humid.
Checked the whole bud, but no insects. My other ideas are mold or stress from the light?
