What the hell is this???

Who cares, The plant is growing out of it....
New growth says so....

BTW are you using a Ca/Mg?
What are you feeding with? list everything!

You might consider supplementing with something with some Iron and some Sulfur or do you know the pH of the in-going fluids?

Looking like you have a slight Ir and/or S def starting...

Doc

Im feeding biobizz alga mic, bio heaven, bio gro and some raw cal/mag, the guys at the grow shop told me because i grow organic i dont have to really pay attention to the ph and they also said the soil buffers it!

it will help also to know what is your water and feeding schedule, also what kind of things u been using with your plants from the beginning, your temps, rh, ph, lights been used, distance from plant, kind of ventilation and all that that will take the guessing work away and u can get more accurate info. good luck!!

OK ph = ignore! They're right. At least be sure your below 7.0 as you'll see why in a sec.
With Biobizz, chances are you will see some early yellowing in bloom. To help prevent this - do NOT change to bloom nutes till week 3 after the lighting change.....If you see it begin in 10 days after that - try upping the N a bit.....

I asked about the Ca/Mg as good liquid one's contain Iron at levels that would cover the def. That way it had to be S alone.....Or high pH.

Now then - Iron Sulfate will fix both def's .. I suspect Ir over S but they go hand in hand....
MAKE sure your below 7.0 in pH as at 7 and above you get limited Ir and S uptake.....Could be the problem!

The pale color of your new growth indicates this def as Ir and some S - more so Ir !
Fix this soon, for better more vigorous growth and stronger plant with better terp profiles..
