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.

3 days in, only cotydelons with no sign of the first true leaves. Have you seen this and has it recovered?This plant was stunted at the start after he couldn't get his hat off, but now looks pretty healthy however it's been 3 days of just cotydelons and absolutely no sign of the first true leaves. Have you had this before and did it recover to eventually grow true leaves?

First Grow 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?Last 3 days I've pruned diseased leaves every morning, foliar sprayed peroxide leaves & topsoil, & added some to watering solution. Is only affecting one plant in tent. Humidity no longer issue (was waiting 4 inline fan). If I keep pulling off leaves it's going to die anyway.

F44: dozens of gnats stucked on buds & sugar leavesHey,
I noticed dozens of gnats stucked on sugar leaves and buds trichomes/resin... I tried to pick them by hand but there are too many.
I saw articles about bud washing which seems to be a good thing except for higher mold risk.
Would it be the only way to smoke bug free weed?

Flushing with RO Water (EC 0,0) or tap water (EC 0,8)?Hi.
I think, it's 1,5-2 weeks before they are ready to harvest.
Tell me, if you see something else in the pics. :)
I want to flush them now every 2 days with only water.
I have the opportunity of RO Water (EC 0,0).
Should i use the RO water or normal tap water (EC 0,8)?

What is shelf life of silver thiosulfate ("STS") in practice?I know it is recommended to use within 30days of mixing final solution.
However, what "works" can often be different from the recommendations. Has anyone used an STS solution they made after 2months? 6 months? How did it go?Other. General questions

Should I wait to flip?Since I just transplanted and amended my soil using gaia green amendments and geared them towards veg. I know the general rule is to allow 2 weeks for them organic amendments to break down, will that deter me from flipping to flower next week or should I wait if so how long?

Bad idea?Will a mars hydro TS1000 be too strong for a 60x60x140cm tent?
I have been using a TS600 and TS1000 in tandem in a tent 4x too big for the light level, I have been growing strong and tasty buds but with low yields so downsizing my tent size to maximise the light.Other. General questions
