ok. first time grow, about a month into the cycle (planted the germinated taprooted seeds april 1st). i just moved them from a 24hr cycle under 2' x 2' grow flourescent tubes to 18/6 under a 400w MH light. they have been under 18/6 for less than a week. at this point they are 8" - 10" tall (est) with multiple sets of fan leaves. from the pics i see the color is good, i am feeding them 3tsp floragro - 2tsp floramicro - 1tsp florabloom per gallon of water and just started that a week ago. the ph of the mixture is between 6 and 6.5.
the substrate is soilless mix in cut down 2-liter bottles with duct tape around them for light blocking, and holes in the bottom for drainage. the plan is to move them to 3-gallon buckets or actual flower pots in the next couple weeks. I have been watering too often (daily) and am going to cut back to every 3rd day or so. i have 2 plants that i am having an issue with. the edges of the leave are curling upward. i thought i remembered reading that's a sign of being dry, but i may have been wrong, as increasing the watering hasn't corrected the behavior.
how soon should i roll to a 12/12 cycle under HPS for flowering? i am hoping once i see the hairs vs the nodules, it will be clear as crystal to me. being this is my first time, i have am uncertain. i have heard people say they go to 12/12 as soon as 2 weeks, others say 6 weeks. are there any signs from the plants themselves that they are mature enough to start flowering?
