I need help! Northern Light has Reddish brown spots turning dark-gray and crispy dark edges on the top leaves! It looks like a different issue from week 6 where gray spots appeared on the bottom leaves? Any ideas? Thanks

Looks like you have or had a calcium deficiency. When you grow under led lights the plants need more calcium. Best of luck the rest of the way.

I keep loosing leaves to some sort of nasty necrosis. It affects leaves at all levels, small and big randomly. I had to remove a lot of dying foliage
At first it looks like a asymmetrical spot of leaf starting to thin out to lighter color then tissue dries and turn black. I have high runoff EC3.3 and I blame Easy boost pellets because I only add rootjuice 1ml/L and sugar royal 0.5ml/L to my water. What is it and how I fix it?

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.

Unhappy leaves
A few leaves aren’t looking too happy. What’s that? Deficiency’s, too much light, too many nutrients? It’s only a few leaves with that problems. What should I do, what would you do? Thank you!

K deficiency? Hard to believe that can happen in 65-gallon pots.Are getting big though.New growth tips looked yellow,hit them with water-soluble K and the new growth edges seemed get green.Some toco-ing, humidity is kinda high. Too intense light(800 ppfd), not enough C02 maybe?

Weed doctors to the rescue
Day 44, fb auto, my happy girl developed those dark spots at the top... Is this a Calmag deficiency? Although I'm giving her calmag every feeding. I think there are also first burnt tips. I'm about to water her tonight, what should or should not give her? Thanks for your inputs🙏
