Maybe we are misdiagnosing deficiencies. Its hard to know everything going on from pics and comments.

I couldnt get to 800ppm (1.6 ec) with 6 ml even fed every time. And i dont let plants stay that high ppm anyway. Target 1.0-1.5 ec for me.

Try feeding a plant like you have and pick one to increase to see how it goes in your room.

Question do you include your water ec number before additional nutes ? For instance my tap wAter is high 2-300 or more at times so my ppm actually only increases about 4-500 - so do you calculate ec/ppm from 0? Or include the water number ?

You need to include the tap water ec because the total is what the plants roots see.

So if i say 1.5 the .3 ec from my water is included. Really 1.2 ec of nutes. 1.0 ec = 500ppm

I never had the problem in the last 5 years but i am pretty sure my pbp grow had gone bad. I use a gallon over a few months at least so it was likely only 3 months open. There was a black sediment in the funnel last time i transfered it. Never saw that before. Had bad deficiencies for the last months. Going right away with the new bottle of nutes (dyna grow this time).

Just something to note with the natural based fertilizer.

Yous think its just coming to the end of the life cycle ? Week 7 of a 8 week autoflower
