    Hey,
    Not sure what deficiency I have here.
    Plants seem to be growing fine. And look perked up and are growing bushy.

    But I have leaves that are yellowing and have rust spots. Some twist and almost shrivel up on one side of the leaf.

    I'm not sure how to treat the problem.

    I do foliar feed the underside of the plants with some Epsom salts. Thinking it was magnesium issues but it hasn't helped .

    I wouldn't personally use epsom salts, and it does look like a Calcium or magnesium deficiency. Do you check PH before feeding?

    Always ph to 6. I recalibrated my ph pen just in case it was out. I'm growing in Pro mix HP. A peat based medium.

    Follow this like the gospel. PH is everything and most often overlooked. Ph chart.jpg

    Great chart. I will attempt to dial my ph in tighter. I think I'll buy drops as a second verification of ph levels
