Potassium deficiency

No shit? Was worried I was seeing a little tip burning, but I guess I'll up the feed and see where we get. Was running about 650ppm before, bumped it up to 850 after rez change this morning. Hopefully it helps out. Is potassium easy to lock out in some way?

With potassium deficiency leaves will go light on the edges in early stage then as it progresses it burns the tips making it look like you're overfeeding it.
Wrong ph can lockout your potassium.

Rad, thanks man. Should I expect leaf recovery or watch the new growth?

Should expect both, the newer growth will be noticeable more so than the recovery of the older leaves as they'll take a a couple weeks to get back to normal
