For my first grow, I over-fed to the point of nute lockout and nearly a total loss. This time I am being lean, and the health of the plant seems pretty good, but I am starting to think I am underfeeding them.
I have been gradually ramping up the amount of nutrients I add, and the PPM is always down to almost just trace amounts (<40ppm) within a few hours. Currently at just about 1/4 strength of AN Micro/Bloom/Grow. Here are some of my readings from the res:
2018-04-02 16:00 42.8 PPM
The solution I top off the tank with is at 338 PPM, and I added 1.25L to the res (4L capacity). A little while later, I measured again.
2018-04-02 17:41 124 PPM
Looks like a reasonable number. Not going to do the math, but it looks right. 20 hours later, it's at 53.2 PPM.
I know the small tank is going to see chemistry fluctuate much more rapidly than a larger one, but this almost seems like I am barely giving the plant enough to survive.
