Nutrients CannabisMingus' Grow Dots - Coco - Autopot experiment

[Dankerson]

I thought it was going to be Mg lockout myself as well, as that is pretty much the one thing I see in my indoor grows. So that's like my number one got to response.

I'm also a let's see what happens more-on sometimes too though. My experience with osmocote type products, as we spoke in the past, has always been outdoors with veggies and they always seemed to dissolve/dissipate sooner than stated leading to the need to supplement. I've never tried them on canna, much less an auto.

I tend to have way more product on hand than I can ever use due to my love of growing. Point being, depends on how you feel about really digging in and playing. Sacrifice vs saving. Of course we all hate to lose a plant not to mention the time, energy and $$$.

DCL has a point. Supposedly heat is what dissipates the osmocote type products, not water. I don't know if I necessarily believe that though entirely. If you do flush you may create an abundance at one time? Dunno how or if that is necessarily a bad thing. You would have to run water through it for a good while.

I'm partially talking out of my ass here.

With that in mind if it is temperature activated I wonder if using a colder water to flush be more effective than with a higher temperature flush?

Just thinking out loud with you here, won't the flush increase the amount of nutrients? Dissolve more of the dots faster and worsen the problem? I would probably do the flush anyways and see if it doesn't remove what's already released and balance it back out a bit.

I have emailed the company twice asking about preferred mediums, strains, auto/photo, just a few basic questions but never got a reply.

There's a podcast somewhere floating around where the owner talks about all of this. He recommends coco and 0 runoff. Basically claims you can use grow dots, recharge and non-pH'd tap water from start to finish. Claims it works for all autos and most photos depending on how long they go and/or doseage.

Yeah - that's my concern too. I'm thinking whatever is removed will be replaced somewhat quickly, but maybe not so much excess P (or Cu if that really is the problem).

The hotter the temp the faster the osmocote products break down. We're talking soil temps here. I dunno how water temp plays into it, though it must somewhat. Again though, I have to believe that water has to play at least a minimal role in them breaking down.

If I were to flush, I would just flush. I wouldn't add anything else. Including recharge. That's just me though. I would try to get back to ground zero.

LOL. I hear you. Lots of flying by the seat of the pants going on here. On the heat issue, I think I'm largely in target range 75-85 per Real Growers/Scotty but I see your point.

Makes sense. Thanks!

I also wouldn’t rule out that it could be a Magnesium deficiency. The cation exchange capacity of coco for calcium and magnesium could still be a factor here.

Every time I get a little lazy with the runoff on my coco plants, especially during times of rapid root growth, things can get off the rails pretty quickly because the coco is sucking up so much calcium and magnesium.

Yeah - I am DGC guy as well and they have discussed that. I am thinking it's a dosage issue, and more specifically cultivar/dosage issue. Other cultivars might like 75g/5G just fine. It would like to find the baseline dosage that works for most - I will probably do 65g/5G next run.

I am treating mine for an MG def and running slightly more grow dots than @CannabisMingus so it should be a good comparison. Although I am in a light soil not coco.

Yeah I would probably have to agree with you there. Even in that podcast he claims to have ran 100+g/5g for autos and it works great. Sucks you almost have to sacrifice a plant to figure out whether you were right about the doseage though.
