Yes - wood ash contains a significant amount of calcium - BUT it will increase the pH of your soil so you'll have to compensate for that...

I might be a bit annoying 😊 will they resume growth or stay stunted due to the deficiency? Thank you very much anyway 👍💪😊

Thank you very much, I've been told about wood ash for calcium supply? Do you know this solution?

She's beginning to show a calcium deficiency... I would give her a small dose of calmag (and do this only once a week). Good luck!

Plant issues... How long to harvest?
Could someone please look at my (only) diary and give me an estimate on when harvest might be? I have microscope pictures up . I think I see cloudy trichomes with the possibility of a few amber. Maybe ready now? Not sure but hope to harvest before plant gets much worse. Thanks!

Yellow spots nute difficiency? Light burn?
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?

Leaf Diagnosis
Could someone help diagnose this leaf problem. It's less than 2 days old. Aañnnnnd, 2 days ago I accidentally set the ppm to 1700? I've since dumped the solution and got it back down to around 700 ppm. I'm hoping someone give me some triage pointers. Should I trim those leaves?

End of Flower, Yellow and crusty leaves ok ?
Hey last weeks of flower and I’m not sure if it’s fine how they are developing, as I started flushing this week they quickly started developing yellow crusty leaves. Should I keep flushing them as I will cut them in 1 or 2 weeks or should I try to balance out missing nutrients?

Tips turning into yellow
We started feeding the plants 10 days ago. Some leave tips started to turn yellow, we think is due nutrient burn. We decided to water them without ferts for once, to flush out the excess nutrients. Is it a good approach? Could it be from light stress? (See pic for reference)

Ph issue?
Hello, I'm getting a bit worried. I'm not sure does this yellowing happen because of my high ph? I think my soil have been moistured pretty long and wouldn't want to try lower their ph with water. Have anyone ideas what is the problem and how could I fix it? Thank you in advance!
