this is a high cbd strain from spain, I had this same problem with it about 4 weeks into flower last time. I am using different nutes than last time but the same nutes and the same amount as on the others.
Nutes: espoma organic bloom 5ml/gal
Mm weird I wonder if @chickenman has seen this as im pretty positive he has this exact same cut ;).
What's our ph at bro what medium ya in? I think she's hungry tho
coco husk/perlite 90/10 topped with gnat nix
feeding every watering with the espoma bloom, just stopped calimagic at 5ml/gal about 10 days ago
it is in a small bathroom garbage can and it dries out fast, I have been watering the last few times from the bottom so I guess it could need a flush
I was tired of buying distilled water so I have been letting my tap water, which is about 190ppm sit in a gallon jug with the lid off for a few days and using it to mix with my nutes.
I'm not sure on the ph or ppm of the water before I added it...
Should I test the ph of the water before I add it and also test the runoff?
Has your room been hot lately? The way your yellow leaves are withering makes me think you have some bad bacteria(pythium) in your pot. If it is a root problem get some enzymes to help battle the problem.
Always ph the nuts mixer before water"very important. It's good to keep an eye on what's coming out the other end as well do you know when there is some bite build up.
Oh and 190 ppm water is perfectly fine to use no need for the disstilled water.
you need to up the food. what medium are you growing in? i dunno if you still have this going but you need(ed) more phosphorous and nitrogen, overall it's hungry like someone else already said. you should have upped the food.
