Does anyone know what type of deficiency this might be?

Picture is attached. Thanks!

Coco? Soil? Nutes? Ec/ppm?
Ph?


Ca and Ph.....maybe

Low ph causing lockout. The necro spots say this to me. Though she might be too green still for that. Need more info like @TintEastwood said.

Sorry for not providing more detail. I am growing in Coco Coir. I recently transplanted from solo cups to 3 gallon fabric pots and mixed in 25% worm castings. For nutrients I am using General hydroponics flora series. My pH is between 5.8 and 6. I haven’t been checking the PPM. I need to start doing that. I have five plants altogether. Three of them are doing well and two of them are having this issue.

I'm a coco grower, but have never added worm castings.

Coco like a consistent feed ec/ppm, PH 5.9 thru 6.2 are most common. I run around 700ppm. 1.4ec.

I use Jacks. This recipe mimmicks Jacks 321 using GH trio.


Good resource.

Looks like over watering to me. Maybe the castings tightened the core.
