Okay cool So it's 1/2 ratio but during veg wouldn't you want a different ratio for more nitrogen? Like 1/1 or 2/1 and then switch it around in flower?

Do yourself a favor anf buy a PPM pen, (15 bucks on amazon) and just feed the 1:2 ratio at about 1000 PPM in flower. If the plant takes 1000 well go to 1200, ect until u notice some slight yellowing of tips, then cut it back a little and hold that PPM.

Lucas works for veg, so would 1:1 micro/bloom. IMO lucas is too much nitrogen for the end of flower, but it works. Id to 1 micro to 3 bloom for last feeding of flower. But that's just my opinion.
