Is this nutrient burn? (brown spots, yellowing of some leafs)

DarbGrowDiariesstarted grow question 1y ago

Is this nutrient burn? I am feeding them according to BioBizz schedule, and was doing so for every watering. I stopped using nutrients beginning of week 8, so I am thinking of brining them back in a few more days and cut the doses in half. Any suggestions? Thanks for the help! 🙏

Thats calcium deficiency. Redish bottom leaves stem could mean that ph is off, calcium issue could be caused by it too. Calmag to the rescue, spots and most yellowing will stay, but plants health should increase.

Looks like you are experiencing a Calcium Deficiency. I would suggest using a cal/mag product and use it roughly 25% more then the recommended manufacture feeding rate the next two feeds. The spots should stop showing up nearly immediately. If you keep seeing them and more issues with the plant, you could have a lockout issue and you would want to correct that. I hope this helps.
