Leaves with a potassium deficiency get yellow, brown, or burnt edges and tips. The burnt edges may look a little like nutrient burn, except the affected leaves also start turning yellow in the margins. Yes to much can actually lockout nutrient intake. Flush with pH water and resume but go easy on feeding

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?

Nutrient deficiency which kind and/or light burn?Do I have some nutrient deficiency or light burn or maybe both? Looks like maybe P or K? I changed my light to a HPS and the plants grew much closer to the light so could be too much PAR/heat so I raised the light. I also had started to add Cal-Mag to my feed just before.

I still can’t determine whether this is a heat related or Nute burn issue. Is it that temps are too high causing a Nute problem? I’ve done all I can to lower temps.

Is this sign of over feeding?Few of my babies in vegetative stage are encountering this problem. Some of the leaves are showing like those in photo. My guess is overfeeding the nutrients. But before I making any decision, I want to hear some professional opinions. Nutrient feed interval is per 4 days.

Yellow edges I had just dealt with a calmag deficiency but adding biobizz calmag, but now the leaves are starting to yellow on the edges. Is it still a calcium or magnesium problem, or is it something else?
