Yeah you want to mix that first and let it mix reallly well before adding anything else. Then PH adjust down before adding other nutrients.Had a quick question @Aqua Man and @Moe.Red if you guys are around- I am getting ready to charge the system with nutes and such and one thing I noticed as I was about to add the Tree Trunk silica additive was that there are noticeable particles in the liquid and I wondered if it went bad or something. I noticed it because as I was filling my pipette, the small chunks were plugging it up. Once I got it to fill partially, I could see a bunch of crap in there. Is this what they call precipitation? I tried shaking the bottle a few times and it seemed like they broke up a bit and mixed back in.
Anyhow, not sure what is going on there and didn't want to waste a bunch of RO water and nutes if there is something awry with this additive.
200-300 on top of whatever your source water and silica addOK, so I got everything in place I think, but am wondering a few things.
GH says my ppm should be 200-300 for seedlings. Well enough. My question is, does this ppm count just the nutrients alone?
I'm starting out with RO water about 20 ppm or so. After cleaning out the buckets and everything, adding fresh RO water, my ppm was about 40 so I'm guessing there was a slight bit of something still in there after cleaning. I took all the water pumps apart and cleaned them and ran fresh water and h2O2 twice, then two trips of just fresh water so I figure that was a fairly good cleaning. Only other thing I can think of is to take everything apart and clean that way but I did not think that necessary.
Anyhow, after adding the silica buffer and cal/mag the ppms were bumped up to 320, which is higher than GH feeding schedule. My guess is that number of 200-300 is nutrients ppm only and not any other additives. So I went with it and added the GH line at previously mentioned rates, a slight ph up, and then added the Hydroguard. Final ppm is sitting at 550, ph 5.8. That would leave a ppm of the nutrients alone at 230, which I would think would be a good starting place for this young seedling.
I dunno, I'm still learning but I do think this gets me on the right track to introduce this young lady to her new home
Looks like the adaptor does not quite fit into the hole? Like the ribs are holding it up? Too big?
Nice resin rails there. I'm a bit jellyFingers crossed he gets this pheno.View attachment 1288145
Yes, I also thought the ppm was a bit high. In the beginning after adding the RO water the ppms were about 40 so I figure there was a small amount of gunk somewhere despite what I thought a pretty good cleaning. Adding the buffer and the cal/mag brought everything up to ~320 before I added any nutes. Doing the math, the nutes constituted about 230 ppm.yes I typically see a slow increase in PH in a healthy system. You must be doing something right.
IMO the PPM is a little high right now, keep an eye on how they react. Some seedlings do well at higher nute levels, others show signs of deterioration. Often diagnosed as light stress. And backing off the light helps this because is reduces leaf temp, slowing respiration, resulting in less nutes taken up. But what you are really doing is taking things out of range to compensate for another setpoint, and slowing overall growth.
Again, IMO seedlings at this stage are putting a lot of energy into root growth. To stimulate this, you need a fair amount of water demand up top via respiration. Ultimately the energy for that comes from the lights. So backing off the light slows things down. This is one of the benefits of running hydro like this - being able to create the perfect conditions quickly. Make adjustments quickly. Not fighting CEC. So your knobs to tune this grow are right at your fingertips, you just gotta watch those babies like a hawk and make sure your settings remain in the middle of the fairway.
These are the spots to watch closely for any changes.

What do you expect from Dragons Flame Mac Dragon bx1?
Is this a short plant? I didn't look up the genetics. Stable or several phenos with these seeds?
