Frustrated w/ DWC + Lucas formula -- what is my issue?

[ninfan77]

^ Notice that mg isn't really absorbed by the plant at 5.5

Also, for those of you touting how you don't have to flush and ph adjust, you're using reservoirs, he's not. Ph and ppl will fluctuate more in a small container vs your larger.

I wondered if that wasn't going to happen. I have no idea what, but something associated with that second bucket was destabilizing your nutes, I think.

The nutes SEEM to have stabilized, unfortunately my pH meter died (cheap POS) but the PPM hasn't started rising, it's actually been going down now... (Recommendations?)

That's normal. It means the plants are eating . I've had a couple of times where some non-nute related problems was slowing down the plant's consumption (temps, mainly). Once I got the problem corrected the plants ate like crazy for a couple of days and then slowed down a lot.

They should also be drinking a lot along with the nutes. Keep an eye on your reservoir levels, and keep track of how much water you're using. It sounds like Rumple is having more luck with the drain-and-replace method of the Lucas formula, So I'd try going with that, since you're using his bubble bucket design.

As for what to do with your plants, I'd wait and see if they recover. Let them finish if possible. I'd only harvest early if it was obvious that they weren't going to make a comeback.
