Okay oldtimey guy!
I get’ yer’ splanation right here!
Its really up to the plants and the grow at hand as I usually grow new seed plants and we all know the challange that can bring.
But as a range with
pure blend pro grow, .2ec well water and say ocean forest and perlite (im using a new soil called mother earth groundswell right now) I start with 5 ml / gallon and work up as needed each watering (2-3 days when mature) up to 20ml but usually a full dose of 20 needs backing down to 17.5 as soon as buds fully set. Then ideally stepped right back down the same 2.5ml increments. Some plants like to hover at 15ml and some seem to be better at 10.
I checked the runoff ec of the plant we harvested tonight at last watering which was water only and it was .3ec. The well water is .2. That was 3 days ago. She was still drinking.
The last feeding which was 6 or 7 days ago she got 5 ml
pure blend pro grow. And if i look 3 days before i bet it was 7.5 These amounts are subject to problems and plant health of course. Picky plants are what they are.
To convert all this babble to a usable ec for my garden environment a max ec with
Botanicare kind trio was 1.4 safely and minumim was .6 or .8 if during transition the ocean forest wears out.
These numbers stepped up slowly and down at each or most waterings were under 2 600
hortilux super hps and had to be stepped up some when i added a phillips 315. During stretch and transition they needed more i think.
Hows that. Man i am really high on Mrs mmg’s carrot cake muffin. And some nice bong tokes. Took me a while to write this. :)
Whew
