yellowing is continuing.... i spaced out re-upping calmag at this location..... nxt time, aside form yellowing the plants are growing well, stil had nothing but maxi @ 7 g per gal, upped it slightly to 7.5 to 8 g per gal to try to fix the yellowing, didnt work, so back to 7 and ill add cal mag and or epsom salt.
Have you checked for root rot? If you are getting more water to the top then the bottom and the top are not drying enough to get oxygen to the roots then it could be root rot.
If this is the case you need to change the perched water level. This could be done by hanging a piece of rope from the bottom to wick the excess water out. Poke a hole and shove the rope in a couple of inches.
Just a guess from me though.
thanks for the input flower farmer, i may try a feeding w just cal mag no maxi.... then go back to maxi.
Well Avi, I'm about 90% certain about what your problem is... It's a design flaw, and I tried telling Jbonez/Zodiac about it. Maybe you'll listen.
Molecules each have their own weight, and are affected by gravity accordingly. Once you add your nute solution, it doesn't stay in solution. The molecules separate, with the heavier ones falling to the bottom and the lighter ones staying toward the top. This also effects pH, creating a different pH at different levels. This is why we add a pump to our reservoirs, to add energy to keep things in solution. This is also why with my racks, I put a separate bag on each level. In my octagon, I use wide but short bags, to keep the root zone more heterogeneous.
It's science...
Sorry dude... but the design won't perform how you want it to and you're going to keep chasing this problem.
To demonstrate this, you could put a tall piece of paper in a shallow cup of micro, and a another tall piece of paper in a shallow cup of bloom. There should be distinguishable lines where the water rises to a certain level, and under that will be the different nutrients. I bet the markings will reach different levels on the paper.
