Can anyone help me discover why my leaves are clawing under and have slight yellowing at their tips? Im using coco pro and rainwater (not ph'd) under a Vipar spectra xs2000 and Mills nutes as directed.

I dont check ppm but the rain water is 5.6ph before nutes. Im feeding them 25ml A+B Basis plus 10ml Start and 2ml Vitalise per 10 lts. Supposedly this is their "light" feeding schedule. The light is 12 inches above canopy at 75 % power. 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

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.

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.

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.
