Hi all,

been a while since I've been here, had a quiet winter to allow the system to cycle more. It seems to be doing good now with pretty much 0 ammonia, pH being around 7.7 and nitrates quite high.

We have peas in the bed which are doing phenomenally well. Everything else is growing fast and strong but I seem to have a yellowing problem.

I think I've narrowed it down to either being a potassium or an iron deficiency but thought I'd ask here.

Hi Jonar,

It's definitely not Potassium, nor is it Iron. The symptoms that can be seen in this pic would suggest a Calcium deficiency.

Cheers,

Hayden.

PH 7.7 you will be suffering nutrient lockout,look at dropping your PH to 6.8/7 then see what happens,just because your plants are showing deficiencies doesn't mean it's not in the system,it might be just not available to them.
