Just to add some pics of some recently finished megacrop grown bud.
Fed as needed in coco "cana", but ranged from 1.0ec initially to 2.0ec later on, with just water at the end as they started consuming less. Hit a peak of 3.2ec in my reservoir at one point due to the cut back on intake by the plants being later in flower.
Edit: starting water was low low 0.05ec tap water fyi
Handled very smoothly.
Only addition throughout was some calcium Hypochlorite as a sterilization agent for my "Dead" reserviors
