5 days old one is leaning any HELP PLZ

HI my babies are about 2 inches and are in 4 inch rockwool cubes one that is the first that sprouted is taller and leaning over, not leaning towards the light but just plain leaning, i have a 400w mh 2ft away, so light is not the problem, i drip 1.5 gallon drips, 3 times a day 24 hr light so every 8 hours, but cubes seem to be heavy still right before watering begins. i think it has something to do with watering. should i do 12/12 watering cycles instead. but only that one is leaning and i have it held up with sticks.

u should use flouros for seed ings so you can limit their vertical growth tll it gets a nice pair of nodes then if it still acts up... process of elimination. by the way use something stalk it up.
