IR,

Thanks for the tips. I have some shultz 5-10-5 liquid fert. Should I mix that at half strength ? I thought the new soil would provide enough ferts to allow a recovery .
Not sure what alternate branching is. Tallest plant is about 16 inches. I have a small grow area. Little better than 2 sq ft and lit by 4 x 20W flo tubes. Don't think light will penetrate too deeply if the plants are tall. Plan to install a screen for sea of green . Also pressed for time. Would like to harvest a crop my early May. But I plan to regenerate after harvesting buds for a second crop . So final amount not so important.
