We will need more info on your grow. What media, strain, lights, nutrients, runoff ph and ppm, light height and type/size, all info you can give will help us diagnose your problem.

I think it might be light because the leaves underneath are fine, but my other auto different strains though are fine
Info: I use Gaia green 4-4-4 and 2-8-4, FFOF soil mixed with perlite blood and bone meal, worm castings. I used recharge 2 times 10 days apart. 300w mars hydro light 15 inches above plant

When was the last top dress??
I can tell you right off FFOF is a hot soil as is and you are adding all those other nutrients . That’s your problem right there. Those yellow tips are nute burn, at least water them with plain ph’d water , no feed for a few waters and you’ll need to get a little runoff to check your ppm and ec to know root ph and soil nutrient content.

Less is more Growmie, stick with the Gaia green, no need for the extra nitrogen and phosphorus from the blood and bone meal

Welcome to the community @Letsgrowmj Great place here!
I’m not good at diagnosing visible symptoms but one out of 3 of my autos showed the same signs. I’m using FFOF/FFHF/perlite and the same gaia green with little worm castings. Yours looks to be in pre-flower (maybe?).
I’m a gaia green beginner and I overdosed a couple photos I got going top dressing too early in the hot FF soil so I’m playing it safe with these autos. First top dress for them was on day 28 and that may have been too early but one was showing signs of pre-flower and I wanted to get them some 2-8-4. Clorosis signs started on the one auto about a week later as it was going into flower. Wasn’t sure if it was the beginning of Nitrogen or Potassium deficiency. I let it ride and progression slowed and quit. All is fine now. 
One of the photos was similar. 
A growmie friend told me GG and FF soil don’t work well together. I think I can prove him wrong. Happy growing

I tried to edit my last post but I had trouble and couldn’t accomplish. I don’t know how it replied to @Mmanson1981 I must have goofed somehow when I quoted.
Just when I thought I was getting good at navigating this forum.

You did fine. And i didnt know that gaia green and ffsoil dont work well together. Im using ffhf this grow and gonna reuse the soil for my next grow. But i would agree with what @OGIncognito said… stop using the bone meal and blood meal. You get plenty of nitrogen and phosphorus from the gg

Just a bit of nute burn from all the goodies in the medium & nutrients you’re giving. You could do a mini flush to get things balanced, if you’re interested.

That’s what I had to do to my photo, it wound up nute locked - worked like a charm!

A week ago
I don’t top dress with it I just mixed it in my medium. Initially
Edit fox farm happy frog not ocean frog
Ok and you gave the bone meal and blood.meal when?? I am also leaning toward nute burn. You can do a flush and get back to good. And then top dress to feed going forward

Ok if undont top dress what did you do a week ago?? The blood and bone meal??
I don’t top dress with the blood and bone meal, I add it to the medium, I topped dressed with the Gaia green 2-8-4 2tbsp for each of my 3 gallon pots and 1 tbsp on 4-4-4
So I put half soil half 6.5ph water and the ph came out to be 5.78 should I maybe put 7.0 water or do a whole flush or what? Haven’t watered in 3 days to figure out this problem
5.8ph with half soil and half 6.5ph water
