Lucas uses flora 3 part not floranova.
Calmag is used if you have RO water and are not using Lucas.
If in coco your ph should be a little higher than if in some other medium 6.0 - 6.1 IMO. I target 5.9 & let it drift up
Actually, the 6ml/gal micro, 9ml/gal bloom is "Heads modified" Lucas formula. Or the H3ad formula. But also calls for some epsom salt, as the extra micro is already supplying the extra Ca needed for coco.The PH for the feed water in coco should always be around 5.8 ....not higher. Not trying to say it wouldn't work, but the proper coco ph is 5.8. And as far as using Floranova with "the lucas method", that isn't possible.... because "The Lucas Method" is when you use only the Flora Micro and Flora Bloom throughout the grow (no Flora Grow necessary). The ratio for soil is 8ml Micro/ 16ml Bloom.... and the Lucas Method ratio in coco is 6ml Micro / 9ml Bloom (and YES to cal-mag if you're using RO).
Still useing that flora nova bloom?Floranova Bloom is amazing . been using it in coco for 2 years now. I love it. tap water +3-4ml/g Calmag + 3-4ml/g Floranovabloom = Gold
im currently using 5g/gallon maxibloom and 1g/gallon epsom salt.Still useing that flora nova bloom?
