Grey spots?

Well this is pretty weird my plant looks healthy but some of the bottom leaves have grey spots anyone heard of this? None of my other plants have this either

Pics? If it's fuzzy and round look up powdery mildew.

the rest of the plant looks great no stunted growth i just topped it but it came from a clone that was sprayed with neem but i dont see how it could come from my garden all my other babies are from seed

Sure looks like PM to me. Likely your spray had too low pH. PM loves acidic, humid and cool environments.

Do a few searches and you will find all sorts of cures.

I recommend Sulphur vaporizer for rooms. Serenade will treat for a bit. Lollipoping is a technique. Keep humidity low and area warm and if you MUST spray be sure its very slightly alkaline.

for sure well my room stays 77-85 Ill prolly lollipop this plant and see how it goes no other plants affected I dont really spray it at all either

Any other ideas or is this definitely pm? I found some grey spots on another clone this guy gave me kinda annoying but can I just prune the infected leaves? Is it contagious?

Powdery Mildew, but to avoid humid ares wipe the leaves and grow area down with warm water and 10% bleach or use commercial stuff

Its definitely pm. It is easily cured with a diluted milk/water mix. 1/10 ratio. I have had this problem, and the milk mix took care of it.

The plants also benefit from the calcium in the milk. You are basically foliar feeding the plant calcium while you kill the pm.



Milk has long been popular with home gardeners and small-scale organic growers as a treatment for powdery mildew. Milk is diluted with water (typically 1:10) and sprayed on susceptible plants at the first sign of infection, or as a preventative measure, with repeated weekly application often controlling or eliminating the disease. Studies have shown milk's effectiveness as comparable to some conventional fungicides,[SUP][11][/SUP] and better than benomyl and fenarimol at higher concentrations.[SUP][12][/SUP] Milk has proven effective in treating powdery mildew of summer squash,[SUP][12][/SUP] pumpkins,[SUP][11][/SUP] grapes,[SUP][13][/SUP] and roses.[SUP][13][/SUP] The exact mechanism of action is unknown, but one known effect is that ferroglobulin, a protein in whey, produces oxygen radicals when exposed to sunlight, and contact with these radicals is damaging to the fungus.[SUP][13][/SUP]

I would use baking sods before milk. Milk is really gross when it goes off.

For sure man what kind would you recommend I mean for sure organic but 1% 2% fat free?

Either is fine.

Yeah I found a mix of baking soda water dish soap and avocado oil imma try that before milk

Get the air circulation going hard in the room too and keep the humidity down my friend and all will be good after you treat that shit. Good Luck

Just be sure to get all the contaminated vegitation out first. Fans spread the spores compounding the problem. Fans prevent PM they don't stop it.
