Oops, forgot to clarify, I meant in the foliar itself.

A quarter teaspoon is typically 1.25ml; they round a full teaspoon up to 5ml because most of the world uses ml, and everything else follows.

Plants don't need niacin to process GABA, but GABA cannot pass through the blood-brain barrier in humans without it, which doesn't mean that it's useless, but it does mean that the things GABA does in the brain are irrelevant to supplementation; however, it does do stuff in the rest of the body...

GABA can't cross the blood-brain barrier alone, it has to be bonded with niacin, and the only way you're gonna get that is a grey market Russian import, which... probably isn't the best plan these days; however, you might find 5-HTP interesting, unlike tryptophan it's immediately converted into...

Did you consider acetylsalicylic acid? Regular SA is more than soluble enough for direct mixing, but in terms of a stock solution it's probably a solid alternative, cheap too. What concentration of GABA did you end up using?

Yo, how did this turn out?

Calcium-25 was recommended at 4oz/400gal, or ~4.5g/gal, which is a much higher dose. Tria is typically used at <1ppm, after dissolving in polysorbate 20, but you can always skip the science and substitute CannaBoost or something similar. So, one liter of RO, one gram of calcium chloride, plus...

Bud Factor X was found to contain 4,400-5,000ppm, which when mixed as per the label works out to ~10ppm. Technically, BFX has salicylic acid, while aspirin is actually acetylsalicylic acid, which aren't quite the same, but the few comparative studies I've found suggest similar effects. That...

I just made the move from a 400W induction light (just one 315W at the moment), which was supposedly comparable to a 1000W MH, and everything looks a lot healthier now. TK is still more spindly than I'd like, but they do seem better, despite being further from the light than they really should...

Or, is this just sort of a holdover from the MH/HPS switch? >In our experience, the 13.4% blue light from CMH lamps would be adequate to grow all species without adding supplemental blue light (see spectral output graphs and summary table). This is what Utah State had to say about the 3100K...

The second meter was a warranty replacement, and I replace the electrode once a year or so. The junction clogs over time and I'd rather swap it a little early than be caught off guard when it fails.

From Hanna RO, DI, or distilled... All the god damn time! lol It was ~125ppm, not RO, just needed a bit more to stabilize. I believe I generally let the RO bubble for 10-15 minutes before mixing (and it will have sat out previously, albeit loosely covered), but the fact that I've cut CO2...

Lol, we're on the same page, I was thinking "RO has no alkalinity". I'm at ~200ppm, but my tap is 550 so I've never really had a basis for "normal" I suppose, just ultra hard, and RO.

The alkalinity of my RO? Wat. I just increased my base until the pH remained stable.

Oh, and yes, I've tried adding pH up or down to buffer, then using the opposite to adjust. No dice, nothing. Is there some special ph up/down you use during flush?

I've got a Hanna combo meter, and I can't seem to pH RO, or the light feeding some recommend. I can get the pH down to 5.9, but within five to ten minutes it'll be back up at 6.3, without fail. I could probably dump an entire bottle of pH down and still be above 6 within a few minutes, what the...

Oh, and sit-rep: Most of it looks fantastic, and pulling out the dead and now light bleached leaves has revealed that most of those tops are still great. The lower branches which burned will likely just end up in with the trim. I initially cut back to 10ml A+B with 6ml PK Heavy (week seven)...

At one point I was hitting them with Open Sesame (5-45-19) in week two and three, but I was following that with Bloombastic; I believe I was in beds, then seven gallon pots while this was going on? Things have been changing far too much from cycle to cycle as of late. This early PK boost...

That was probably part of the issue, a result of raising the EC instead of the frequency, but between time and hand watering it kinda had to be. :( Mind if I ask about your nutrient situation? I didn't really consider how little phosphorous was in Big Bud, people said something about the...

I have not turned the temps down yet, but probably this week. Purpling has started, but this purpling is different from the previous purpling. What you described is what's happening, just at a greatly accelerated rate. The first time it wasn't that fast, but now that the plants are bigger, so...
