Are there guidelines of the actual volumes of nutrient solutions to apply to plants based upon their sizes?
I have a dozen girls outdoors: 1 late planting @ 3’ and the rest 6’x6-14’x14’. They’re fed 1x/week; the larger plants have been taking up to 1gal. with no sign of overfertilizing; doing great actually,
It’s high-drainage, sandy soil so watered daily and that may account for capacities.
But, really, I’m just guessing. So far that’s worked out but I’d be happy if there were rules-of-thumb already worked-out.
