Black Spots on me leaves! Help please!!

Phosphorus....deficiency during veg. dont go to crazy with the neem, you will suffocate what there is of the roots. If you got gnats in there, you are in for a real treat, i will tell you that.
The dark dead spots result form the stomata not being able to function properly which results in cell tissue dying and turn gray or black.Could also be phosphorus toxicity.....

Damn thanks for that answer because i didnt know what top tell him.i never experienced that

I never go more than 1/6 of what the ferts say per gallon of water. In my flood and drain table it's one day fresh water, four days ferts then change the water. I use the spent water from my budders for my moms.

I dropped some BTI larvacide in there just a bit ago, but I haven't seen any gnats flying in this tray. Although I did see a few dead gnats floating in the bottom. I'll lay off the neem I think that may be part of the issue.

I actually just read another post where a user had used too much neem and the leaves looked curled and had black spots on them just like mine.

Most of the yellow leaves were at the bottom I don't even know why I took a picture of them when that's kinda normal. thanks!

If you look closely at the upper leaves you will notice that the fert levels are just a tad high.

I agree I think it may be more than just one problem. I think it may have been my tap water that has a ppm of 460ppm and 340ppm through a brita filter. I used store-bought water with 9ppm and actually ph'd the water correctly this time.

I failed to mention that 3 of these little clones were used to find sex then reverted back to veg, and they look really weird (really green, small twisty leaves all bunched up kinda like a baby palm tree, and lots of nute burn) the rest are normal green and have a bit of yellow and a few black spots. I'm going to just water with pure ph'd water for the rest of the week. if any more burn or spots show up in the next 2-3 days I'll flush them real good with ph'd water.

I think all in all they will survive just fine. This strain is really resilient. I wish I knew what it was. it smells kinda skunky in veg like a bowl of warm spinach soup and in flower it smells like nothing unless you rub your fingers on it and then it smells like chocolate mixed with really sexy sativa medicine smell

Good job on the detailed photos, btw.

Tap water is a bitch sometimes. If your tap is really alkali, you have to usually hit it twice with the ph down over a period of 3-4 days to get it finally stay put.

Well tomato....you have come up with a good solution, but jesus, dont get carried away with the flushing, them things need to breathe.You may be on to something though....cool.
