I believe this is potassium deficiency. K deficiency causes internal temps of foliage to rise and it causes the protein in the cells to burn and degrade. Usually happens on the edges of the leaves.

My Royal Creamatic has the edges of their leaves pointed down, loosing soil and some yellowing in the older leaves. I've tried to use google but there were many opinions about this. Have the feeling that I should just give ph water for now. Any ideias/advice? Thanks

Did I do the right thing? Pls check my update on this week!Can my Growmies check my update on this week please? Ppm shot up and I noticed nute burn. Weird bc I have only added water since last week. I cleaned the pump, removed air stone and lowered ppm. Definitely seems like too much nutes - hoping they’ll perk up.

Calcium Def/Wilting or other issue?So after 24 hours of feeding it CM Plus it doesn’t look any better. I’m hoping there is not another underlying issue. Environment remains the same. Pics are 24 hours apart. Or will it take a few days + before seeing improvements?

Wilting and yellowing leaves after vinegar water solution I sprayed a mixture of 1/4 spirit vinegar + 3/4 water under the leaves to get rid of aphids (which may or may not have been the problem) earlier today. Now checking on her, I see yellowing of several leaves and wilting of others, which has me worried... normal, or a problem? 😳

Do you think my plant is dying?Do you think my plant is doing senescence or is it a problem with bugs or deficiency? If its senecence, do you think I need to stop feeding my plant and start flushing? I'm in 4-5 weeks of flowering and its an autoflower. Thanks
