Ok, all that is fair enough, and thanks. I considered that it might just be that and simply adding calmag would do it. Understood about one or the other and being in between assumption and bro science. But we seem to agree that the base problem may lie in the fast growing autos sucking the Sohum dry of certain nutes perhaps faster than photos, and if that were not the case I wouldn't have any deficiencies. So the reason for the action we seem to agree on. It's the action where you differ, and of course I will err on the side of caution. However, I do like the top dressing with Geo/bokashi/frass, cuz no way can that hurt and can potentially only help - they'd be active by fattening up time, last two weeks. I'll hit them with one more cal mag (it isn't like I haven't given them any...) and not flush and see if it gets worse or stays/improves, and I'll top dress a half dose of Bloom nutes with bokashi and frass. Maybe help replace some of what has been drained.First of all, let me get on you a bit for your usage of the phrase cal/mag deficiency. These are two different issues and you will usually have either a calcium deficiency or a magnesium deficiency.
Molasses has very little nutrient in it that might cause a lockout. Not only that, but one of the nutrients that it does have is magnesium. It does not make sense to me that adding magnesium could cause a magnesium lockout, or calcium either for that matter. And you talk about getting your microbes up to speed, even though you are aggressively feeding them the perfect sugar to keep them going, even if the plant had somehow given up on them or the sohum ran out of minerals.
So here we are again, somewhere between assumptions and bro science. I don't believe a flush is your answer. I would like to see some pictures specifically of the symptoms you are seeing, but I think you have enough clues here to get to a better answer than flushing. Flushing is to clear a problem, salt or lockout, but you haven't convinced me that molasses could cause a lockout. As you said, it will also wash away vital nutrients... is it worth that risk on a theory?
You mentioned that the sohum is keeping up with the photos, but it is your autos having the problem. Fast growing autos. hmmm. Could it be that since they are growing so aggressively that they actually are using/needing more calcium or magnesium than their slower growing photo cousins? I think this is much more likely than the lockout you have convinced yourself that you are having. You are growing quite aggressively too, hitting them with massive light and additional inputs, you speak of phenomenal lift and transpiration... is it not possible that you are simply looking at a simple deficiency and that more Ca or Mg could solve it? I would up my calmag to maximum dosage and I would consider a foliar of epsom for even more Mg to look for a resolution to this, before I would flush.
Does that make sense based on what you said?
