Its really just that one plant thats having major problems. The Two Muchachas have a couple spots of brown, but thats on older growth and doesn't seem to be spreading. And the Forum Stomper seems fine as well, at least for now. I've been bottom feeding, probably part of the reason that pot has gotten hydrophobic? Not sure how to handle the flush and yucca as far as that goes, probably shouldn't have switched methods partway through. At least Im learning today, lol. And I don't think it will end up being a serious issue, just a bit of frustration on my end. Thanks again!
If you are bottom feeding don't flush or top feed otherwise you send that salt concentrate back into the root zone and throwing off the pH wven worse. As water evaporates up through the soil, salts are deposited along the way. I don't think is a big deal if the top of the soil is hydrophibic if you are bottom feeding as long as there is moisture in the root zone. Get that pH sorted out first and foremost. And just give plain old pH proper water for a week. There is plenty of stuff in that pot to keep her going for at least 2-3 weeks. Better to under do it right now vs. Over doing and trying to correct mistakes. It's all part of the growing/learning experience
