Lotus?

Using almost the same method as you, growing in fox farm the neuts typically last about 30-35 days I typically top dressa a week before then to slow it to "cook" in the soil to be available to the roots by the time the FF runs out. The only thing I add now is Basalt Rockdust for calmag and a bit of extra water retention you can check my GG and Cafe Racer diary for decent mixes using Gaia green. Then just top dress every x amount of weeks x=size of pot/1.5
