switching from grow big to tiger bloom

[EHLE]

I'm using foxfarm nutes and just switched my plants to 12/12 on the bottle it says to use at first signs of flowering but I wasnt sure if that meant once i switch to 12/12 or to wait until i actually start seeing some bud. thanks

I would wait until the 2nd or 3rd week. Basically when you can tell when they are girls or boys.

You can switch now but the plant may yellow a bit early if it uses lots of nitrogen.

are your plants nice and green....? if so, i'd start using the bloom and get off the grow. unless you're flowering a super long sativa, they should have enough N to finish. need a little more info. how big are the pots and how large are the plants, how long have the plants been in the pots, what's the ppm reading along with the ph reading in and out, are you giving them the full line of ff nutes, etc. the more info you provide, the better we can help you out....pics please...

start mixing them together and every feeding move the ratio from more grow big to more tiger bloom.
