Root Aphids or Fungas Gnats? Identification Please

Been having mysterious deficiency problems with my organic soil grow for months now. Have tried just about everything treating the problem like an over fertilization, deficiency, light burn problem until i found a thread about fungus gnats. Checked my soil and put some yellow sticky traps down and sure enough theres something flying around and larva in my soil. I just need an ID to confirm what i have now.

I vote fungus gnats

I have those little fuckers too. This is my second grow. I thought I got rid if them after the first. I cleaned everything really well and used new soil.

There's lots of ways to control them. I'm currently using a spray made of rubbing alcohol and water. I will probably buy some neem oil when I get a chance but the alcohol solution is definitely helping. I spray it on the top layer of soil, not the leaves. it seems to kill most of the larvae. You can use yellow sticky traps to catch the adults.

Im on my second cycle of having the mysterious problems with my plants. This is a quote copied from another thread on icmag but its my exact problems. I had been treating my plants for cal/mag deficiencies with no results whatsoever.

"I have the SAME problems either in late veg or early bloom, not long (1-3 weeks) after I put them under HPS light. After they look extremely healthy throughout VEG, I start to see a leaf here and there with random "blotches," generally at or near the leaf edges, then at the tips - patches where the leaf is papery, tan and obviously dead. Then the patches grow larger, progress to all tips of the leaf which often curl (when dead). Then many other leaves start taking on a bit of a sickly look, getting intervenal chlorosis and becoming more translucent and turning a lighter, more sickly green. Then most of the well-established, healthy fan leaves (middle-aged) all start to "get it" and die of progressively, while the plant continues to grow and put out new shoots on the main growth points."

I've done a lot of reading today. Just ordered some Gnatrol and Biowar Root pack and Foliar pack.

It depends how much doomed they are. When you already see leaves dying massively, than your roots are eaten by their larvae and you will do shit about that...

yea but i have a perpetual grow so im hitting the younger plants. Im probably just going to chop all my flowering plants. Some strains are already ready anyways. The rest will be chopped a couple weeks early.
