@ewic I always switch between a liquid fertilizer and epsom salts for nutrients. Alternating between them, in 10 day intervals. So once they sprout to a fair size, the first month I do fertilizer-salt-fertilizer, next month salt-fert-salt, ect. Make sure they get a lot of water inbetween, but stay more hot and humid is most important. Mulch is good, well draining soil, and water when the plants have a chance to absorb some of the days heat.
