Yes, excess calcium can cause serious problems. I would flush your plants with water equal to 3 times the size of your pots to restore the medium. If you're using a calcium/magnesium nutrient, I would stop doing that. If you're not using a specific calcium/magnesium nutrient, I would use less of any nutrient that has a high amount of calcium. There's also a lot of white powder on your leaves. Is it yours or did it just appear? I'm asking because it could be powdery mildew that will ruin your buds if you don't treat it. Make sure to address these issues before switching to 12/12 or it will affect your final yield.

Hi @Elmota! Whatever toxicity is in place, flushing the medium with loads of water is the only way to get rid of the old salts/nutrients. Next time you should probably focus on a good soil rather than giving heavy amounts of nutrients frequently. Hope this will help, let me know in the comments section if you need any further information, and happy growing! 👊

Deep Ridges in leavesI have a whole strain (3 plants) exhibiting a general lack of vertical growth; but also deep veins and ridges causing eveb more malformed leaves. Same setup as my other 3 plants of another strain that are thriving.
Looks like pH issue? Maybe this strain needs lower?

Possible N ToxicityI believe I have a N toxicity issue on my hands. Leaves are a dark evergreen color, and I'm noticing some leaves are curling left or right. I've experienced the full out clawing action a while back but never like this. Is anyone able to confirm? How do they look overall?Thank U!

Fan leaves are looking like they are turning into dust. This is only happening on 2 out of the 4 plants I have going. Thinking it is a ph problem but I've been watering at 6.0 -6.5 since day 1 and just only had this issue. Seems to affect lower growth first.Week 10

Spots on leavesI'm still dealing with some spots that seem like cal-mag lock-out/deficiency but my PH is at 6.2-6.5. I think the light was too powerful I moved it up from about 16" to 18". I hope to have a lux meter soon to confirm any light stress issue.
Still look like PH fluctuation?
