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.
