New Grower First Grow - 4 Different Auto Strains in Coco

[Death The Cultivator]

Day 4, evening addendum: I went ahead and fed the plants tonight now that I'm quite sure I didn't over-water yesterday after all. .5/.3/.3 M/G/F, 3 mL CalMag (with a full dose being 5 mL). This came out to 230 ppm. I'm about to collect run-off to measure volume (using my handy DIY run-off extraction tool, buy yours today! )

Now that I will be feeding more often than I'd initially planned, how should this affect my CalMag use? Should I be quarter or half-dosing CaliMagic now? I had previously planned to give a full dose every 3 or 4 days (in fact, when initializing the pots, I put in a full dose).

Is the important part how much CalMag is given over time (meaning I should divide that full dose out over two or three feedings), or is it mostly about plenty in each dose of food? I am thinking the latter due to the whole DTW concept.

I may be putting too much credence into some of the coco guides I've read elsewhere. They recommend lots of CalMag for coco--in fact, it's the only nutrient many people seem to recommend giving more of than the nute companies suggest. GH's recommended schedule says no CaliMagic until week 2, and then only 1.5 mL. Does something about coco coir mandate MORE CalMag than a traditional hydroponic setup? The comparisons I read are mostly between coco and soil as opposed to coco and traditional hydroponics.

In the gym, we have something called 'bro science'. It's basically bros spouting pseudo-scientific bullshit to look like a boss in front of novices and polite people, and I think every hobby has it some degree. I've read too many conflicting things over the past week and am trying to sort out the 'gro science' from the real thing.

When I mixed my 10 gallon reservoir I did 1/4 strength of everything until I cleaned it out. Coco typically needs CaliMagic because it's inert and if you aren't using tap water you're probably getting none but too much can cause a lockout. I would feed it at the same strength as the rest of the nutes every time.

While going light on other nutes is prudent in the early stages, I'm thinking with the tendency of coco to lock in calcium a full dose (or nearly so) of CalMag is probably warranted even early in the cycle. Would be happy to hear some more opinions on this, though.

I'm using moderately filtered water (Culligan level 4), and while I'm not 100% sure if it removes much calcium, my tap water hardness is quite low at 18.9 mg/L, with calcium at 5.9 mg/L.

Day 5: Fugue State still wasn't breaking the surface... I carefully checked it out and it hadn't developed a bit since I planted it--tap root broke off in my hand when I picked it up just now. I'm guessing I buried it too deep and it got compressed when I watered. The replacement SC is coming through, though the stem is flat with the surface as it hasn't stood up yet. The original SC definitely wasn't viable, so in a week or two, I'll move the replacement to the center of the pot it currently shares with the dead original. The new FuSt will be behind the other plants obviously, but if I have to, I can put the pot on top of something to elevate it to the level of the others at some point. Maybe I can just level them out with LST later--the age difference isn't going to be that big... Feeding again at .5/.3/.3/5 M/G/M/CalMag.

That's three plants visible now with one new FuSt in the incubator.

Post-feeding pics from just now. I have to get a generic camera app that won't do automatic (failed) color 'correction':


WC


FoSt


SC (what's coming out of the seed is actually white here... it just broke the surface so I think it will be turning green soon?)

WC and FoSt look a little droopy, but is it too early to be concerned about that?

You are being too impatient. some seeds can take 21 days or more to germinate. Kilimanjaro can easily take that long. Never handle seeds just put them in the starter block/sponge 3/8" deep keep lightly moist and warm. Wait - mother nature handles the rest.

Get a 5000K CFL bulb on the end of an extension cord and hang it in your tent for taking pictures. Turn other lights off. We need to see the natural colors of the plants to be able to determine their health.

Here's the re-shoot:

FoSt


SC (this one is gaining color seemingly by the hour as the cotyledons open.)

All look normal. Thanks for the light change.

All look normal. Thanks for the light change.

And thank you for the reassurance.

I would actually advise against moving the plant to the center. Not only will you disrupt the roots which is a big no-no, but you will actually have the plant in the perfect position to LST to the other side. I saw a grow where they intentially planted on one side of a fabric pot for this reason only.
