Possibly Potassium Deficient? Based on ALL the pics I could find, but not sure.
I noticed these brown splotches and leaf edges on one area bud and pistils of my Orange Sherbet last night. Based on what I can find online, this might be potassium deficiency? This is mostly on one spot near darkest edge when tent closed. Thanks!

Look At This Pigmentation!
Lower fan leaf vs upper fan leaf in the canopy. The difference in pigmentation is wild! It almost looks like its bleeding. . , , , . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ?Why?

Leaves have developed "claws" at the tips that bend downwards
My leaves have developed "claws" at the tips that bend downwards. I suspect there is too much nitrogen because I probably used too much root juice. (Approx 8ml, scale was inaccurate) Now my question to the professionals: what can I do to fix the problem? Green greetings! 👽

Leaves are gray/brown and curl down. HELP!

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same. I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…
