Has anyone used a flood to drain or use the Titan flo n grow

I’m growing in hydroton and I’m wondering what nutrient schedule to follow for general hydroponics.. please help. The Lucas formula did not work for me!

You can start low 5/10 then 6/12 if plants are ok. Then raise to 7/14 I never went past 8/16. 8ml micro per gal and 16ml per gal of bloom. Lucas isn't a set formula. Just double the bloom. Hope I said all that right. Using the normal formula right now.
