LordRalh3 is right- you don't really need all that shit "they" want you to think that you need but you must provide them NPK plus the full range of macros. When you are using chelated synthetic nutrient like fox farm you are giving the plant dissolved salts it can use immediately whereas in a natural grow the microbial life present in the soil feeds the plant. Synthetic nutrients kill much of the micro life forcing you to continue to use dissolved salts which the plants are fine with as long as everything they need is given to them. They will use more N during the transition to bloom but gradually need more P and K as the plant focuses it's energy on bud development instead of increasing it's own mass. The plant will seek out what it needs & use it as it is needed; more is just waste & will deposit those salts in your soil to build up over time which is why regular flushing is needed. Whatever you dump on them will not trigger more vegging or more buds - only bigger lights produce bigger buds- the light cycle is the sole trigger for flowering a plant has. Nutrients feed them when they are hungry- that's about it.
Your plant looks very healthy nice job so far - so just keep doing what you are doing - the plant is just about to pop off with pistils real soon it looks like so wait till ya see them & that is a good time to switch over to your bloom formula and/or HPS bulb; of course you can do it any time you want but 14 days into bloom might give the most benefit. Some growers don't even bother with using veg nutes at all because nitrogen is relatively easy to provide in the soil with a just handful of worm castings.
