Assuming your a bit fimilair with the five gallon e-bucket. Changing your 5-1-1 mix to a 3-1-1 mix. At first glance what problems should I be looking for. Reason for the proposed change is to increase the wicking action for the moisture to reach higher in the bucket. After inspection of failed tomatoes have noticed very very dry conditions higher then the root ball which very low in the due to being leggy.I also noticed the same condition in tomato being planted at the optium depth.
I'm assuming increasing the % of the peat and the perlite would increase the wicking action up the bucket of moisture. What you say ,sir.
