Helpful charts for making cannabis nutrient deficiency diagnoses
I think I may as well just post these here charts up in their very own thread and then put that in my sig line, because I spend a lot of time posting these charts that I use regularly to help me make diagnoses on all my plants, cannabis included. One is specific to cannabis, the others...www.thcfarmer.com
right off the bat one or two yellow ones need some more N clearly, the browning on the lowers is possibly Potassium but also possible nute lockout from improper watering of coco...You need to start feeding 150 PPM every third of fourth watering, and bump it up by 50PPM every outher feed until its nice and green again.
and also i can tell your mainly in coco with some peat prolly...you been letting them dry out?

HOW TO WATER COCO FOR BEST RESULTS.
Ok writing this cause i see this issue often and rather have a thread to link than explain this each time. This is not my work but a collection of info from many members here and I have put into practice myself. So first off COCO is NOT soil. For best results we want to keep it saturated...www.thcfarmer.com
cuz your pre mixed soils should have enough food for them for that long, if you let coco dry too much you can encounter problems. check out the article above about that.
