What is this? Any suggestions

[YodaKush]

This is one of my feminized kushberry plants. Last night I noticed a few very very small white specks on top of the first set of leaves, and now it looks like this. Does this look like a thrip or spider mite problem, or mold? If the pictures are too hard to read I will try to provide better close ups. Thank you

did you get water or fertilizer on the leaves? are the spots powdery or dusty? whats the stuff in the bottle next to the plant? check the undersides of the leaves closely for bugs. pics are a bit blurry but it looks like water got on the leaves and caused a bit of damage.

Yes I have gotten water and fertilizer on the leaves. I mist my plants occasionally, and the water has an extremely small pinch of blood meal in it. The bottle you see in the picture is a home made 2L bottle c02 generator. The other night I was adjusting the levels of c02 coming out of the bottle via the pin i have in the cap, but the pressure blew the pin out and my grow area was momentarily sprayed with a yeasty sugar water mist. I did my best to clean it up and sprayed my plants down to make sure none of it was, or remained on the leaves. I also have an air purifier which supposedly cleans the air with a uv light. None of my other plants seem to have been effected. I examined for bugs but nothing. Thank you for the reply

looks like a salts build up to me. If your gonna foliar feed you need to periodically clean the leaves with skim milk. Use a humidity dome instead of spraying babies.

I recently transplanted this plant from my seeding starter mix soil pot to a much larger pot with an organic base soil of 10-5-5 which I mixed sparse amounts of blood meal into. Do you think that the new roots growing down into that soil may have nute burned the leaves?

it looks like a bit of burn from moisture on the leaves. you shouldn't be giving them much fertilizer yet. if no other leaves become effected, you should be fine. just keep an eye on it.

I will definitely take your advice on the humidity dome, i'm already on it thank you. Can you elaborate more on the salt build up? I occasionally mist, but the amount i pinched of blood meal into the water is extremely small in ration to water, as i've always read that less is better. About a pinch to 24oz of water and it never even dissolved so i'm not sure it even effected the water. This could cause a salt build up? If so i will stop foliar feeding all together

Moisture burn.... I would have never thought of that. I have these babies under a 1000w mh and thought they would benefit from mistings but that makes sense. Thanks mate

if thats a homemade co2 maker, thats your problem.

happened to me, bubbles going up the pipe and dripping on your plant.

Hey Seanos, Did it kill your leaves or did the plant recover?

What I mean by salts build up is anything left behind after the water is gone. Sometimes it's white, but sometimes it looks like glitter. This stuff will clog up your leaves so to speak. The same thing happens to your growing medium and roots a nd resevoirs. Solids will drop out of the solution and stick/buildup on anything they touch. For example take a bucket of water with some PPms of solids in it, drop in a teaspoon of PH down in it. The cloud you see is the acid dropping solids out of your solution. The solids dropped are no longer in the water. They fall to the bottom or stick to the sides and I call this salts build-up.

Hello Chucktylah, thank you for the reply pal. It was very helpful + rep. I am ceasing foliar feeding altogether. Hopefully the problem stops there, the new growth seems to be unaffected. Would it be beneficial to attempt to clean the damaged leaves at this point in hopes of unclogging and restoring it, or just leave it be?

 

[YodaKush]

I will try to search for it, but can you elaborate specifically on cleaning the leaves using milk?

 

[CHUCKTYLAH]

Just gently wipe the leaves down with a paper towel with skim milk on it, or you can spray them with selzer water that says NO SODIUM on the bottle. Make sure to loosen the cap on the sprayer and don't fill the spray bottle with too much cause it will expand rapidly and squirt out the sprayer. Neither skim lilk nor sodium free selzer water will leave things behind.
