Possible potassium deficiency in flower

BigZX · Mar 31, 2021

I believe I have a potassium deficiency. I’m in week 4 of flower. I’m using gh 3 part nutes. I gave my plants a half dose last watering but am still noticing the deficiency spreading. Should I give my plants another half dose yet, or should I wait? I’m afraid of burning them up. Also, should I give them all three bottles or just the bloom? TIA

What's your medium? What ppms are you putting in and getting out?

The medium is soil. My last feeding was 705ppm. The runoff from that feeding was 1300ppm.

Can I take a guess that your running LED's? If so whats the power output currently, how close away from canopy, tent size? Also, what size pot are you using and how often are you watering? If you can give me as much information and give pics if possible will make it easier to sort.

use tap water r.o. water has no micros that plants need

your top dressing and using liquid nutes? not recommended. you got way too many variables to be able to pin down exactly what the problem is. first grow or two best thing to do is to keep it as simple as possible
