My plant is limp and the pot is still wet?

I’m going to guess you have a nutrient lockout or PH Lockout.

There may be s build-up of salts in your growing media depending on what nutrients you are using and how strong you are mixing them.

If this is the case, the first thing to do is use Plant Flush to try and get the plants to release some of what is binding it up.

A Foliar Feeding is only a short term solution to get nutrients into the plant. A Foliar Feeding is not a bad idea, but it is not a fix for this issue.
