When to use Neptune's Harvest Fish Fert. 2-4-1?

Ok I went to my local grow store and could only find Neptune's Harvest Fish Fert. 2-4-1 mine are 6 weeks old now, I've used some GH FloraMicro 5-0-1 & GH FloraGro 2-1-6 2 days ago and transplanted them to 5 gal bucks.

When should I use the Neptune, and the only other fert of that brand they had was seaweed, any help?

Thanks Much.

well, seeing as it is higher in phosphorus you should probably use it right before you switch to 12/12 and then during flower. also kelp is supposed to help with tight bud production... but that is unconfirmed.

I am about to goto 12/12 this weekend actually they will be 7 weeks old, should I go ahead and use the neptune now or a day or less before I change lights? I know another noob question... one day I won't be a pesky noob and I'll help others.

i would go ahead and use it now. i tend to start using my bloom nutes about 2 weeks before i put my babies into 12/12.
