I am on day 52 of flower with my Barneys Farm Night Shade in soil, under CFLs. I germinated 1 feminized seed, veggd it, took 2 clones, and then vegged them all some more.
I vegged the mother for nearly 14 weeks (outrageous!) and the clones for just about 5 weeks each. I threw them all into flower mostly to put the mother out of her misery. The clones rooted/veggd/flowered without problem and were nowhere near as particular as their mother.
The mother plant was quite finicky compared to my other plants currently growing (Nirvana Blue Mystic) as well as the clones taken from her. She was more sensitive to nutrient levels, pH, and light placement/penetration than anything else in my room. Couple her sensitive nature with the unfortunate 3 days she spent in a 95+ degree closed grow-room (in laws came to visit!) and you get a plant that I had to drag kicking and screaming to my current near harvest point.
The clones on the other hand have been looking tremendous, but only as of late. All 3 stretched (2 clones and mother) a very significant amount during the 1st 3 weeks of 12/12 and I had to do some fast and furious LST work just to keep up (height restrictions). Id tie down particular branches and then the next day Id have to move the tie-down points to tie down different branches or to keep the current branch at its former level.
The clones themselves looked to be the bastard step-children of my current grow until about week 6. I really thought about scraping both of them (way too stretched to amount to anything, their bud sites looked wispy and unproductive) and using their lights to move along my superior looking BMs. I stayed the course, and was rewarded for it around week 6. I came back from a weekend out of town to find that the clone buds had about doubled (to my eyes). They have beefed up quite a bit, as has their mother, and I am having a really hard time not chopping them right now!
I gave the mother its last feedinga few days ago and since she has been on nothing but RO water mixed with molasses. The clones received their last feeding yesterday (as they seem to be a few days behind the mother as far as new development and trichome color). They all have responded well to molasses added to their nutrient-free waterings and all are free of any signs of mold or disease (knock on wood).
Nutshell: They can be finicky so dont have a heavy hand with the nutes until you get a handle on their particular tastes, they stretch until around week 3-4, the buds put on a ton of weight at around week 6, stay disciplined with your approach and they will turn out great.
