How do you know mammoth p caused foxtailing? Not being a dick just asking. I’ve been using it for a year and never had that problem once. If you use recharge after week 3 of flower that can be the cause of that because of the nitrogen in it. Even the owners of recharge say not to use it in late flower unless you have a bad nitrogen deficiency.
@Studabaker, It's all good!👍 I discovered it was mammoth p through trial and error, as I've since completed grows in the same setup both with and without the mammoth. The foxtailing symptom may have occured due a reaction it might have one of my base additives or water quailty. You are definitely right about the recharge though, as I used it far too late in the grow and I'm sure it contributed to this case lol
