flower power ??

just started my 12/12 to flower[ the do and don'ts] i need to know 8 plants under 1000hps temp are good no bugs should i be spraying the plants when in this stage using a mg flower boost 15/30/15 is that a good fert need some tips its my first grow I'm a the point don't want to f--k up the plants some are 20" some12" mean and green orange bud // mazar trying to send some photos but i keep messing it up help

I dont foliage feed my plant(spray them) any nutes because of the possibility of being burned by the lights. That looks like a good ratio for bloom nutes but I would add some grow nutes to it as well so you can keep those fan leaves as long as possible.
If you do have some grow nutes mix up like 2 parts bloom nuts and 1 part grow nutes so you have a little more even ratio

check out this thread. It helped me out a lot

thanks that thread has some good info ill try keeping the grow nutes up and watch the leaves //so yuor saying dont spray the leaves at all? thanks for the advice

lots of people do spray the leaves but I dont. I have my veg room on a 24 hour light cycle and its not good to spray them when the lights are on(could cause burn spots). I dont spray in the flowering room because I dont want to get nutes on my buds. I usually have various stages going at any given time so there is always some buds in there.
