Hi downunder, thanks for the advice on micronutrients. The nutes we are using now probably do not have micronutrients since I can't see it mentioned on the label. I will fix that asap.

That seems like a pretty good recipe. If used preventively when would you start feeding that to your plants? For now I will stick to ferts w/ micros but I might give this a try next time around.

The links you posted are both dead, but I think what you posted was helpful enough for me. Thanks again!

canuck grower Reviewed by canuck grower on . K deficient? Red stems, necrosis on leaves, but no yellowing I have read through the FAQs here and I think that I may have a K deficiency. Mg sounds possible but less likely. I think this is what necrosis is, but there isn't really much yellowing. The necrotic leaves are slightly paler than the others though. So I have 2 out of 3 K deficiency symptoms. Here are photos to help my descriptions out. The middle finger has some spots near the tip. The second photo from the bottom of the leaf shows it more clearly. We have been feeding with 5-30-5 bloom Rating: 5
