Nute burn with low ppm runoff??
Ezzjaybruhanswered grow question 3 years ago
Having significantly lower runoff than input, as well as higher pH from run off seems like it’s hungry personally.
Something is almost immediately displacing that feed and spiking the pH.
So it could be the roots are hungry and quickly up taking the feed, or the coco could be stealing some of the feed if not properly buffered.
When the dissolved salts in the feed are immediately displaced, this causes the pH to go up because most nutrients are slightly acidic.
I know it’s weird you have slightly burnt tips but that’s my best guess is up the feed a bit, or double frequency of feeds..

Maybe that strain is more sensitive and does not require as much feed?
The foliar feeding you are doing could also be at play here. could try to lighten up that amount vs the solution your watering with.
If its still showing signs of over feed and all the other things are locked in.
I would go by what the plant is telling you and lighten up a bit on both topical and root nutrients.
Good Luck and Happy Growing!

Maybe PH Lockout?Hello everyone, can you maybe help me? My Black Cherry Punch has some kind of problem. I suspect it’s a nutrient lockout caused by the pH value. I flushed it two days ago, and the drain had a PPM of 1000 and a pH of 7. The plants are at the beginning of the 2nd week of flowering.
