It's Nitrogen deficiency. Just because you can't cure it doesn't mean the diagnosis is wrong.

Could be root lock? The roots aren't taking in the nutes, despite the feedings. Try flushing. If that fails........T R A N S P L A N T....:-O

ya your soil could be locking up some of the nutes..

shes a little over 5ft tall. and huge. any idea how difficult transplanting would be not to mention the shock to a flowering plant?

Yes...fully...that's why I put it in CAPS. Seems like the plant is on a downward spiral and this is a desperate move. Flush a couple times (allow the plant to recuperate between flushings) and see how it does. Then reintroduce the nutes. Remember hempie, to allow enough time for the plant to take in the nutes. Don't expect immediate results, like next morning after a feeding to see the yellowing stop. It could take a few days for the plant to take in the nutes and show the results with new growth. Good luck.

what size pot do you suggest? is 4 gallon atm.. ill have to get more soil also.. i see a big mess in my future

well...whats the ph of your water...an whats the ph of the nute solution...to acidic mabee

i use bottled so its neutral. 7.0 and not sure of the feed its in the grow room. shes sleeping atm

Hemp, I didn't catch it but I am assuming you are in soil? I have no idea how big your root ball from a 5' plant would be but look at your current pot size and go up a size from there. But remember to try flushing first before transplanting. That should be your last resort this late in the game. Here's another thought, why not cut a few clones, JIC, and get them going. You can flower those after just a couple days vegging.

i bet your nute soultion mixed with the water may be throwin off the ph...an if its to acidic thats what could be causing the soil/root lock....check the ph of the water/nutes together
