Yellow spots nute difficiency? Light burn?

CannaFluffstarted grow question 6y ago

I noticed spots on both LB and NL that seem look like nute deficiency, my best guess is cal. I will check pH of soil runoff at next watering to eliminate lockout as a possibility. I've heard FFOF soil runs out in about 4 weeks, maybe that? Light burn from water drops on leaves?

Hey Bro I would say you have a zinc deficiency Prevention • An excessively alkaline pH causes most zinc deficiencies. Maintain an adequate pH. • Boost the zinc levels in your compost with pumpkin and squash waste. • Good microbes play a huge role in zinc absorption, add beneficial fungi to your growing medium. Solutions • Lower the alkaline pH towards the ideal range. • Stop overwatering. • Use a fish or seaweed foliar spray to boost zinc levels. I hope this helps you😉

Mängel von Pflanze #3 In week 5, I discovered deficiencies in one of my plants and tried to fix them, unfortunately without success, as you can see in the pictures. What could I do differently next time to avoid this? Or what can I do now for my last plant that isn't showing any deficiencies yet?

Blattprobleme bei Pflanze (Wahrscheinlicher Kalziummangel?)I have 2 plants in the tent and one of the plants is showing quite a few deficiencies. Many leaves are now yellow with brown spots. The other plant doesn't have these deficiencies, both were watered the same, etc. A few days ago, I used dolomite lime and worm castings.
