GMSgrowsanswered grow question a year ago If their not drinking much now it may be due to some salt buildup in the soil. If you see any clawing of the leaves or spots coming on, this would verify it. Adding more often would only compound the problem. I would skip a feed and just water. By the end, they drink a lot less, but I find that to be the case, about a week or 2 before their done.
