Alright now 6 days into flowering I am encountered a problem that I don't seem to be resolving effectively. 2/3rds of my plants are exhibiting symptoms that I have diagnosed as potassium deficiency. If you goto this link: http://www.icmag.com...88&page=1&pp=15
you can find a picture of potassium deficiency and my plants look exactly like that. This problem only showed itself 2 days into flowering, prior to which my plants were a lush green 100% of the way through. The moment i "diagnosed" that problem I proceeded to try and resolve it logically. My organic grow formula NPK 6-4-3 has only 4 parts potassium for every 6 parts Nitrogen etc, and since my plants had been watered regularly, and manufacturer instructions followed I concluded that the flowering period demanded more potassium and the plant was merely communicating to me that this was the time to start giving it, that i should switch to my organic bloom formula NPK 2-6-6 allowing for a higher potassium concentration, and hopefully leading to my plants revival. Here is the problem 4 days after, my plants look no worse and no better. They are still growing, exponentially, all new growth is green, the plants are ridiculously bushy causing the lower leaves and branches to get far too little light, and this is causing them to go limp but as far as I'm concerned that is just part of the plants genetic makeup and I'm not going to mess with it.
What I need to know is: was switching from NPK 6-4-3 to NPK 2-6-6 and appropriate
response to my plants potassium deficiency?
If the treatment of a potassium deficiency is effective, does it cause the yellow edges of the leaves to return to green? or does it merely prevent further degradation?
Again, the question here is of treatment techniques, not diagnosis
, since the very informative link above has inspired a great deal of confidence in me regarding my diagnosis skills.
