Easy Cheese day 48 Deficiency

[Autosynthesis]

Hello all.

My auto easy cheese has rust spots with some yellowing on the top leaves. Two lower fan leaves with dieing edges. Started about 5 days ago. 2:1 Fox Farm OF and Fox Farm LW in 3gl smart pots. Using fox farm nutes and Advanced Nutrients sensical grow and bloom. Only used the bloom sensical once so far when I noticed it. Grow Northern ms0006. No issues till now. Distilled water ph'ed to 6.45+-. Hope I have time to correct and with not much loss to yield.

Thanks for any help in advance.

rust spots generally indicates cal/mag deficiency. Any Idea what your runoff ph is? could be locking out other nutes

If in doubt flush her out.

I'll have to check the runoff. It seemed to have started after I did a flush before switching to bloom nutes. Flush and test runoff it is!

Flushed her and runoff was at 5.9. Added some lime to the soil already. I need to run another gallon or two through so should I finish off with a light nute mix, if so what kind, or finish with water? I have advanced nutrients revive, sensical grow and bloom and fox farms lineup. Thanks again!

She dose look hungry, after you flushed last did you feed rite after the flush?

Rough Calculation Guide:

Here's some good info on ph.....
If your runoff pH is higher than your starting pH, use this equation to determine your soil pH:*
Soil pH = Runoff pH + Difference

If your runoff pH is lower than your starting pH, us this equation:
Soil pH = Runoff pH - Difference.

For example, say your the starting pH of your solution before it goes in is 6.5 and the pH of your runoff is 7.0. The difference is +0.5, so using the above equation:
Soil pH = 7.0 + 0.5*
Soil pH = 7.5

If your starting pH is 6.5 and your runoff is 6.0, your difference is -0.5 and using the above equation:
Soil pH = 6.0 - 0.5
Soil pH = 5.5

I last flushed her on 3/23 with just water followed by a feeding at 1.4 on 3/28 and one other after that. As of right now I flushed 3gls water at 6.6. Runoff got to 6.25. Want to get it higher but not sure what to finish with. I have multiple nutes so I'm sure a certain combination would help best with her needs.
