I have some blue dreams showing the same marginal chlorosis in different soil and the yellowing has progress further inward. It feels to me like a deficiency but thank you for the links avenger.

Actually I've been trying to find that tomato deficiency link you age me a while back. Could you give me that link again??

Anyone have trouble getting copper sulfate and sodium molybdate to dissolve? I always have blue and pink powder at the bottom.


On a different note, the marginal chlorosis is progressing. What does It mean that it's only on the newly mature leaves? All I can figure is that itsimmobile...

Did you try boiling the water you are mixing the copper sulfate and sodium molybdate into?

[plantingplants]

No. I guess i should make stock micronutrent solution..... I could just pH it down as a preservative.

Looks like there is to much of something. Last thing I would do, is boil down micro sulfates and add more.

Try something more forgiving, worm castings, compost, liquid kelp. Compost tea really helps balance stuff out, and keeps it cruising to the end.

Kelp is so diverse, full spectrum. Add to much soluble copper and I imagine you will regret it.

I didn't mean boiling down micro nutrients and adding more... I meant using really hot water to mix the dry micro nutrients into solution

i like to use aloe and/or yucca when making micro-concoctions {i have been adding for Cu, Mn & B} the saponins help suspend it in the solution/provide for a better mix

PP Have you checked the EC and pH of your soil recently?

[plantingplants]

Yes not that particular pot but that soil is around 0.21 ec (that's 2:1 method.. So 0.5 with probe) and 6.9 pH. I'll check that one. Just watered in Pacific Gro, gyp, and micros and have been using low pH water. What are you thinking?
