Maybe check out this thread Help: Plants look sick, diagnosis needed and that should lead you to a few possibilities since it looks like you have the same issues

[kenelma]

I use a pen. I clean and calibrate it on every use.

Hello Kenelma,

I have/had and issue that looks a little bit like ours as well. My problem came from not checking Ph and when I started I was using the drops and there not good enough for being accurate. It was recommended that I flush with Ro water that's Ph to 5.8 for my soil-less mix. My first flush I added about half that amount (5gal water/5 gal pot) and removed the damaged fan leaves. This way it would be easier to notice any new damage. I have defiantly seen an improvement but not a 100%. Im going to flush again with 10 gal and and a fertilizer application after that and see how it goes. Im using LED so I've been adding 6ml of Cal/meg instead of the 5ml per gallon but think I might go even higher on my next grow and see if that helps.

This is my first grow so this is what im doing. Good luck

Fwiw the fellow in the link I first posted seems to have settled on fungus gnats as being the problem...
