15-15-15 Fert Ratio

My plants are a month in a half old now and about a month outdoors. I just put them (13) in the ground today with promix soil that gives them nutes for 3 weeks.

I found some 15-15-15 Fertilzer in my shed yesterday. I has no instructions however of how much of a water to nute ratio I need to mix. It is a blue crystal substance with a 15-15-15 ratio. I will use this for veggin and will switch fertz in like aug/sept when they start to flower. I will give a 1/4 ratio for like a week and gradually move up to full strenth in the next month.

okay back to this no instructions bullshit. So how much should i put in,,, lets say 1 litre of water? 1 tbl spon? how much??!

thanks

p.s There are also alot of really small ants at my area like quite a few all in the soil. Will this effect my grow?

Thats hard to tell, it could be a weak mix or highly concentrated. that matters quite a bit when determining a tablespoon per gallon ratio or whatever. Do you know what kind/brand it is?

Uhhh ill have to check tommorow.... I just cant beleive why the fuck it doesnt say on the label. It has all the safety shit and first aid but to mix ratios! hahah
ill get back to you man
