some kind of nutrient issue?
So I recently got a free bag of Growstone Coco Mix from the dude at the local hydroponics store, who said he wanted to know what I thought of it. I put a few peppers in it and now they're showing some splotchy chlorosis as you can see in the picture. None of the peppers in my usual mix show any problems right now. Plants in both mixes are being fertilized the same.
My thoughts are a nutrient availability issue due to differences in either substrate pH or water retention. Any ideas?
