The leaf at top left is growing out from the fimming a few weeks ago. I tend to feed when pots light to lift. The water butt is brand new, this is my first rain water grow. Other than that I dont know whats happening. Ive got 5 plants and its only affecting one. Thanks for replying.Usually clawing is overfeeding...but those look under fed by their color...has something been gnawing at the leaves in top left?...maybe your rainwater is polluted
Perhaps since your rain water is already super low in ph (btw 5.7 ph is as low as I’d ever go in coco generally kept at 6.0) after adding nutrients you are way out of range thus nothing is able to be taken up. Get a ph pen or paper and ph your feed.The leaf at top left is growing out from the fimming a few weeks ago. I tend to feed when pots light to lift.

Yep, I think you're right. My "mentor" dosen't ph his rainwater and his results are excellent. But I'm old enough to know you can't simply copy someone and expect the same result. Cheers for the advice.Perhaps since your rain water is already super low in ph (btw 5.7 ph is as low as I’d ever go in coco generally kept at 6.0) after adding nutrients you are way out of range thus nothing is able to be taken up.
