Is is powdery? White powder mildew. Spray with 40 parts homogenized milk and 60 parts water. Repeat as necessary to keep it under control. Can spread to other plants
GrowingGrannieanswered grow question 3y ago
And yes.... it WILL spread to other plants... guaranteed.... I would spray them as well even if you don't see any signs of it on them....

This is powdery mildew and it's a b*tch to control much less get rid of... you've got to get the humidity down Down DOWN! And you've got to spray your plant all over - use a 2% isopropyl solution and do it just before lights out or you'll burn your plant. You should also wash everything in your tent with the same solution... the spores are lurking there and will come back on your plant if you don't. And get several fans in there... get as much air movement as possible... This stuff spreads VERY quickly and will kill your plant in no time at all....
Good luck...

Looks like mildew...you can mix 50/50 isopropyl alcohol and water and spray the plant down completely. Make sure non drips into the growing medium.you can also use peroxide.

I'm under attack!I think I have a solo predator here guys! The damage is localised to the left main branch in 2 places and the top of the main cola and just below.
I have made up some washing up liquid pesticide and drenched the whole plant and vegetation around.
Could it be something else?

Brown spots and holesHad snails and aphids earlier, but knocked them out. I'm these brown spots / holes in my girl. Don't think they're the snails and don't see any bugs.... been rainy and fairly cool, 60-70F. PH is currently high at 6.9. Any thoughts or recommendations for a mostly clueless newbie?

Fan leaf finger progressionI read somewhere that a healthy plant should increase fingers with each set of leaves. Wendy had two 3 fingered leaves, one of which wasn’t clearly defined. The next set of leaves look to have one with 4 fingers and one with 3. Should I be worried? Does she look healthy?

In the middle of the picture from day 25 there is something weird going on with the new growth (next picture is more detailed). One side is growing really slow, the other looks like it never grew/was eten/something. It is kind of brown/red-ish. Is this a deficiency or windburn?Week 4
