Please take a look at the last photo of week 10, the close up of a cola. Does this appear to be the start of a K deficiency? There is tip burn on some of the plant as well. Refer to my notes with watering issues for past 2 weeks. All nutes listed ph ppm are correct. Thanks!!

Deficiency?Hey everybody, I’ve never really dealt with deficiencies in autos as most of my experience is with growing photos outdoors. Does this look like a magnesium deficiency? These just appeared over night on just two of my larger growing white widow autos. Please let me know, thanks!

Brown spots on the leaves Hello, everyone. After replanting, this appeared on some of my flowers. I think it's probably stress after replanting, but I'd rather ask you more experienced ones. Thank you in advance for the advice 🙂

First time growing/Need help in late flower Over the last 9 days my plant has gone from happy and healthy to sugar leaves pointing straight up near the top of plant and drying and curling up on the lower levels. Is this from too much light or did I over feed late in flower? First grow/ no diary. Can I save or do I chop?

Leaf issues. Lockout? Need to Flush??Leaf issues started showing up in 2 of 3 plants, progressing fast. Soil runoff tests have been v. high (2000ppm+) so we're assuming it's a lockout issue. We watered 1 day ago, with 200ppm solution so pots are still very wet. Better to let them dry out a bit or flush right away?
