Red-tinged yellow spots on one fan leaf

Looks like residue from spraying and thirp damage. Best of luck on the grow.

have mites been fully ruled out of the equation for the small white dots? The mosquito dunks should be killing the trip larva in the soil and skip using DE, it does jack shit when its wet. The white residue on plants maybe DE leftovers that got a bit wet? Need more info. Good Luck!

Interesting comment there.

and as you said freecain white stuff everywhere could also be residue from spraying it's not totally clear from the photos.

tho' i m not sure about thrips, their damage are usually more irregular and less circular, so small white dot could be early sign of calcium deficiency as well.

Since this is a duplicate question, just delete it! I would definitely trust m0use's answer to your other question on this topic... which is why FreeCain has said what he said... he seems to like taking other people's answers as his own... check out his diaries (there aren't any)...

This must be the answer you are looking for. There is a few issue it seem: -white powdery mildew that you could treat spraying 4 part milk 6 part water (white stuff everywhere) - thrips that you could treat efficiently with SPINOSAD (small white dot) - calcium deficency (medium yellow dot on leaf tips)

I've answered your previous question but will duck back in here to tell you I would be MORE concerned right now about the larger white spots you've got going on because this is powdery mildew and a killer of harvests... The yellow spots you've identified could definitely be septoria which is another fungus and would be treated with the same fungicide I mentioned in your other question - the GrowSafe... I was also scrolling through your other questions to see what other issues you had encountered and wish you had chosen an answer to each one so we could get some idea of the progression of your grow... I know many people come to this page to see if someone else has a problem they have and then look to see what was chosen as an answer ... it helps everyone! Let us know what you decide here! Good luck!
