Shov,

I read over the entire log this time to see your nute program.

I didn't see if your alternating plane water and nuted water.

Reason I ask is when I went to doing this all my problems went away. My therory on this is when using nuted water every watering any nutes left that did not get absorbed by the plant are then added to the next waterings nutes, then even more did not get absorbed and building up over time causing nute lock.
Alternating between feedings gives the plant time to absorb all the nutes.

Also when transplanting the soil with no roots will build up nutes with every watering.

Just an idea for you to ponder, but works for me and I know you have seen my grow.
