the tips could be burning, but the side leaves look like magnesium or early potassium deficiencies. If your using the bloom micro grow nutes like in your diary have you been monitoring the EC and PPM numbers? and have you measured the runoff PH? I see you PH your water to 6 with coir as your medium, the liquid nutrients PH range is between 5.5-6.2 could try dropping that down to 5.8 and see how they handle it. If the coir was not buffered before hand it will need a infusion of calcium and magnesium. some coir companies prebuffer it and this step is not needed. Best of luck

@m0use I did a flush today and checked the runoff PH and it was at 6.5 I flushed them with 5.7Ph water but somehow that brought the runoff PH to 6.8 I don't have a ppm meter yet unfortunately. Thank you so much for answering! I appreciate it so much!

It does appear to be some tip burning which is likely from over feeding. Or too much of some nutrient. I see some mild interveinal yellowing as well.. keep an eye on that. Could be a magnesium issue

Leaf discolouration. Nutrient deficiency?Leaves are discoloured and clawed. Started about a week ago with yellowing of tips and clawing at top of the plants. Now lots of leaves are slowly changing colour. Thought it was nitrogen toxicity but my runoff is 330ppm. Are they deficient in nutrients?

Organic peat control I think my plant is being eaten but gnats and it looks like nutrient damage on it but I haven’t given ANY nutrients to it. What should I do? Can you diagnose my plant? Any remedies? I heard cayenne pepper can be used for a pesticide is there other things? Does Neem oil work well?

Brown spot on leaves I'm experincing a bad situation. Leaves are becoming brown in the margins and I can't understant exactly the cause. Probably there are more causes, some phosphorus deficiency caused by low temperature but I'm not sure that's the only diagnosis. Someone could help me?
