That’s very nice, organic with Kratky !
The Pre-Empt, OMRI-listed Organic Hydroponic Nutrients will certainly interest people who weren’t sure they could grow 100% organic in hydro.
Thanks for sharing, did you always use kratky ?
What was your first grow like and when ?

Aloha & we do lava rock pumice 50% with peat, or coco coir and add the organics that the plants need like chicken pellets 4-3-2 NPK as Pre Empt comes from Florida and shipping costs are way too high. One could also add some fine ground bone meal of KNF vinegar based bone extracts. First grow was in the barbed wire Da Nang Viet Nam 1966 with bag seed from mama san in the village down the hill.

Ok Vietnam so long ago ! Those bag seeds made so many lucky growers.
Thanks for the details, I keep that in mind (if I had to grow now I’d go with worm castings and kelp meal but in the end it really depends upon what is more easily available in your environment).
