Thank you, I will change my approach with the pots next grow.

I am using the source fertilisers for the first time. I have tried to follow the directions on the website and some information isnt clear and I cannot find any documentation on the composition of each product.

The instructions say to use Gro and Flo A+B first, does this include Elements? As I have always been of the impression that CalMag needs to be added first?

My RO EC is less than 0.1 ec, therefore has minimal to no iron content. My plants seem to be showing sighs of Fe deficiencies. Is there any Fe in these products? Where can I find composition documentation?
