just switch when you feel it fits you, plant won't care, and sure I try to help you, but looking at your pictures your on the right path, just need to get the experience and continue to do research as you always able to learn, agin, its not that complicated, its not magic, keep it simple, use logic, think nature, some Ppl. think they Etc. can buy a 1000W and place it in the closed over a single plant in crappy soil and just use a lot of different nutrients and out the other end pops out Buds
keep it simple, try to copy nature indoors, nature when its optimal for weed, and take advances of the ups of indoor growing and try to work around the downs, like the artificial light source that is limited (no mater size) to a few or 3 ft, need to grow/train your plants to keep em in the zone, keep em green keep em healthy often the problem can be too much love and attention, just let em do there stuff, they know how if they got the concisions, think they done it on there own for a "few" years
