At 4 weeks in flower I have had yellowing leaves brown spots and brown tips. I looked on the forum but can't figure out what this is. Ebb and flow 4in rock wool flooded 3 times while lights on for 2 min. They are 17in tall ak 47. Hydro flora nova bloom 700ppm was 800/840 ppm last week but thought I was burning them. The res stays at 5.8ph. Brown tips all over/ brown spots on some leaves and yellowing and curling up. Thanks plus rep for help

1000w in cooltube 20in above them temps never go over 78f day and 63-67 night. No the ridges are not burnt to a crisp.

waiting for a pic...
sounds like a nute issue... Floranova bloom by itself wont cause that though... did you add anything to the rez, do you have airstones in the rez? I've seen things like humbolt gravity foam up a rez with airstones... made a nasty mess...
I'd say dump the rez, clean it out...
run up to another 700ppm of FLora Nova, and then add 100ppm of Liquid Kool Bloom (for around 800ppm)... stick with that mix for the next two weeks.. then bump up slowly with more Liquid kool bloom to a total of 1000ppm or untill you see slight tip burn...
also.. did you shake the floranova bloom bottle before you used it?

Your plants will do this in flower. When mine start dying off, I just pluck them off. They have plenty more. It's better then doing a whole bunch of different things stressing the plant losing yields because you're in flower. Just keep doing what you're doing. Harvest, and smoke. I've seen people harvest weed with the ugliest yellow/brownest leaves.. And smoke was good
