Un-idenitified Problem Getting Worse!! Pics

[fourtw0]

Some of you may have seen my last post, if not:

I've discovered some weird white markings on my leaves, like some kind of chemical was in my sprayer and it left residue on my plants. After buying new sprayers and boiling all the water I used, the problem is only getting worse. It has went from white markings to burning the leaves and is getting progressively worse.

Fox Farm O.F Soil
70-75 night 75-85 day
30% humidity (up until yesterday when I bought a humidifier, its now at 65%)
15 days old since germination process started


Any ideas!?!?!?! I also have a very small gnat problem, but today I bought and applied neem oil and traps.

what kind of lights are they under and how close?

your misting them w/normal water? why? you could be cooking the leaves. water magnifies light and burns the plant.

3 CFL's 1700lumen 6200k about 6in away and a 250w mh 26in away from a circle of 5 plants 15 days old. they were under a 4ft floro up until around day 10

yes. my lights are a good amount away, this could still be the problem. I've stoped misting either way so we'll see what happens.

This is the only plant of 5 that are this bad but the other ones are starting to show signs too. I don't think it's bugs though

When your leaves curl like that, its a pH problem. make sure you water is 6.5. I just recently found out my tap water was at 7.5! At this point your plants will be getting weird amounts of nutrients, which will cause the curling

Are you sure your "small gnats" are gnats and not thrips (a flying, leaf sucking insect). Usually, the gnats orient to the soil. If you turn your leaves and have stuff flying away you may have thrips.

Don't wanna argue with anyone, but pH issues are really rare early in soil grows. If they happen at all, they come late as a result of metabolism of too much ammoniacal N or overdose with unadjusted nute solutions; too early for all that here. FFOF is heavily buffered on both acid and base sides, and can easily take up water 1 or 1.5 pH points off of ideal.

had that before in the start of a grow, i usually get it on my shitty tiny leaves down the bottom of my plant at the end of flower aswell.... its a micronutrient deficency, just cant remember which one....

never caused me problems with my seedlings

Yes, its fungus gnats im pretty sure. I check the underside of leaves 3 or more times a day, havent seen one bug under any of them yet...
