Fe EDTA & Fe Gluconate

[rjordan393]

Will dosing these two iron supplements on alternate days cause any interference?

I have been dosing Fe gluconate (0.3 ppm) 2 hours after dosing NPK. The following day, I dosed CSM+B & Fe EDTA and both together gives me 1.1 ppm Fe. The major elements get dosed 4 times a week and the minor elements 3 times a week. I am preparing to raise my Fe level to 2 ppm but I like to know if the Fe gluconate will cause any interference with Fe EDTA? Or should I ceased dosing Fe gluconate? I am just concerned if using these on alternate days will cause a problem.

This is fine, you can combine them also and dose at the same time.
If you add say 20mls of 5% vinegar to 500mls of tap water, this will remove any/most of the KH and keep the tap acidic, which is good for storing ETDA and Gluc.

I combine Fe Glut, ETDA(CMS), and DTPA Fe all together.

Thanks for the tip. I did not add any vinegar on my existing Fe supplements. One of them, the Fe gluconate was filled on 05/11/2013 and kept in a cool dry location. I am about to use it. Do you think its still ok to use it?

Should be fine.
