I think it was cold rain and it was just enough it stressed them a bit. Usually black or purple is a sign of too chilly. If roots get too cold it can do this as well. Like a dwc set up. My bet from what I know is cold. Only time I see this unless it is fading.

If the night temps get too cold it will cause plants to turn a black or purple color. If they got cold then that was the problem. If so they will recover but leaves won't fix themselves. Good luck 🌱🌱🌱

Then it would be from the rain and it drying out. You shouldn't have anything to worry about. Just watch out for mold or mildew, but if its drying up everything should be ok.

Dark tips it seems to me that the tips of the leaves have a very dark color, it looks like an excess of nitrogen but in three weeks I have never fertilized and the only additions to my biobizz light mix are a sprinkling of guano kalong and 10% of worm humus biobizz.

Please see the 2 photos marked in the diary. Is this a classic PK burn? Did a feed with no MegaCrop, no cal-mag, just PK boost at diluted dosage. The coppering and yellowing has come sudden. Leaves are crispy where burnt. I hear its easy to burn with PK boost. Did I do that?
