Quit dicking around with the light schedule.

Personally, I'd put 'em under an 18/6 schedule, and leave 'em there for a couple/few weeks to recover from this abuse. If you keep switching, and not allowing acclimation to the new schedule, they'll turn bad on ya. Never put a suffering plant into flowering. If you keep it vegging for the next couple of weeks (barring any further abuse) the chances of hermaphrodites diminishes.

Although it is possible to grow plants under a 24/0 schedule, it isn't optimal, and it can do more harm than good for a suffering plant.

If you are going to offer 400w of light, it would be a much better plan to get a 400w HPS. It can be effectively used throughout the growth and flowering stages. Provides many, many more lumens, and the usable light penetrates deeper. If it is a sativa dominate, the 400w HPS will be necessary. Your existing lights will not penetrate the canopy very deep, nor do they have the lumens of an HPS.
Rusty Trichome Reviewed by Rusty Trichome on . Photo Period and Budding Problems Hey guys im new the forums and happy to find a good community. So i have some questions I have been growing and I have a sativa plant that is about 3 months growing now. What happened is i let it grow on 24 hours of light on flouresant bulbs 60w total. Then when i thought it was tall enough put it to 12 hours of light under those bulbs. After 2 months of vegitative growth and 1 month of flowering i did not get any flowers nor bud. I have many calyxs on the nodes between branch and stem but the Rating: 5
