Underground Pleasures

Ok I grow in coco often. I dunno where you got your information on how, but this is how. Coco is a high irrigation inert substrate. Basically hydro in a bag or potter. So it always stays wet. Tons of run off. 5.8 ph in and 5.8 ph out of bottom in run off in vegging. Anything about a 6.2 the roots are locked out in. Dropping coco ph will require lots of water. It is ok you can not over water in coco unless you dump a straight stream in 24/7. It holds air like perlite protecting roots from over water. You also look to be feeding really heavy for a auto AR 2 weeks. They should be literally just getting a taste of nutrition at day 7 to 10. Then slowly increase. My first feed is about 4 drops of each of my 3 part and cal mag at 1 ml to liter the whole grow. If you got a decent cal mag you won't need more. Every feed though. Coco absorbs cal mag. I feed every other morning after I flush coco and get a ph reading. Then adjust if needed. Then I put a gallon on nutrition in. Which I use 3 gallon fabric. In coco they don't need anymore, but roots will fill them nicely. Coco is not soil don't treat it as such. You will encounter major issue, and lose a lot of the grows potential. I feed every other and splash just enough ph water on them to keep them wet between feedings. In heavy bulking in flowering I like to add bloom booster to splash. Hopefully this helps.

Hey there Seedlock , autos' stems "thicken up" quite quickly and it can be a bit difficult to train them and especially difficult for the training to pay off. You want to start as early as possible, something like 10 days , dont forget an anchor. if you leave it too long the bud sites get all stunted , that's the thing. you can tell by the appearance of 5 pointed leafs, try to do all that beforehand. Buy yourself some time by removing the leafs as they split or even beforehand.

Hey there Seedlock, you had a bit of root problems , you can tell from the droopy leafs and other symptoms. It's basically a problem from overwatering because of the top cover that you have there. Basically if there is not easy drying so mold and other issues can happen. so if you follow a much stricter wet dry cycle the problem should fix itself based on your feeding schedule that you already have. just start again with bacteria and fluvic acid, appart from this little thing , you're really doing a good job. Hope this helps ! 🚀

personally I'd say you shouldn't need it,, with whats being used...should be getting all it needs from those..

silicate doesnt really make a difference when you're already feeding calmag, but the beneficial bacteria always works though, it usually does help , you can easily add them to benefit during flower. hope this helps ! 🚀

Looks like magnesium to me.
