Nute burn with low ppm runoff??

Capo420started grow question 3y ago

I am confused with my run-off ppm being a little low pH being acceptable but still showing new nute burns. Any ideas?

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!

Yellowing/purpling leaf tips outdoors Im experiencing yellowing/purpling on upper canopy leaftips of my outdoor organic cannabis plant in week 2 flower. I'm feeding via compost+dry amendments so over/underfeeding is unlikely. What might be the cause? nutrient lockout? Relatively low temperature (57-75F)? pests?

I don't think this is nute burn...So I thought I had a case of mild nute burn but I haven't given the plants any Bloom or Calmag since last Friday, only water so I'm wondering if this is a nute burn issue now. Could it be my PH? Last I tested my run off it was at about 6.65. What's causing this?

yellow spots on upper leaves, towards the end of flowering, I grow in a Coco ,flowering 8/10 This is my second attempt at cocus I work with Plagron nutrient solutions(Coco Nutrient) I follow the table, there were no problems on my first try.. should i stop nutrients? I always mix the water in a bucket, so I can't spoil it either, because most of the plants are healthy, ph 5.5 is always between 5-7!
