Trace reduction

Trying to get to the nitty gritty on the Plantex reduction dose suggested now. I am a little late to this party. CSM+B is now 28.6g per 500ml portion bottle....was 40g
Was 1 ml per 10 gallons....now 2 drops per 10 gallons.
Yikes...who caught up with this past problem?
What were the symptoms of OD?
Is the suggestion across the board with suppliers?

Hi
Sometimes 0.01 TE(Fe) is sufficient and 0.1 TE(Fe) cause problems. It depends on substrate and water mineral content, mostly KH. In higher KH water 0.01 TE(Fe) may not be enough and more is needed, usually 0.1 TE(Fe) is more suitable.

This is daily dosing before lights go on.

i dose 1/5 to 1/10 micros of what EI suggests. started doing so long time ago when was fighting with curled/crippled leafs on a few stem plants.
i also add EDDHA iron to the tank now. the amount is to tint water slightly, that way i always know there is not iron shortage

Very good. Big picture here. So if the iron was the number one element that was targeted to pull back on, where does that leave the other 7+or- elements in the mix? They will be short as well correct? Is this re-thinking of dosage quantity the reason why we are seeing custom Micro mixes?


Thanks____

i dose strictly per EI only difference being micronutrient amount dosed is lets sat 7 times smaller. in addition once a week i add EDDHA chelated iron(amount is to tint the water slightly). this form of iron is stable in all PH and stays available to plants for very long

What product do you use for Micro mix please? Are you adding this to your tank measured dry or are you making a dosage solution?
I use Sequestrene 138 Fe on my nursery plants. We have a high pH and this product is equipped with EDDHA as well. Great product so I will try a very small amount in my 45 gal.
I am sure it will tint it red.
EDDHA = Ethylenediamined (o-Hydroxphenylacetic) acid
