Indoor P/k/n strengths in 2 gallon soil pots help

[madmable]

hi, i have just been given a free flower booster(good allegedly), it has a P/K/N rating of 18-18-20, i grow in a sheeted room, 3 x 400w hps with up to 50 autos in 2 gallon pots with compst(brought mixed with compost from wormery) just wondered what people are using and more importantly with autos, as i only need water1 time per nweek, 2 in hot summer, what is the best ratio to look for or is something more different better, budget an issue so ideal mixes would be good for me to search not ideas on expensive bloom feeds, i can find these, just wanted to know the best P/K/N rating for autos, obvoulsly the P/K ius vital, not sure of ideal amounts for this and if N needs to be as high. thanks guys!

If your like me and dont use all on line expensive nutes try miricale grow all purpose food for the veg stage 3 to 4 weeks and bloom buster for flower stage. Start with half the recomended dose so you dont get any burn. Shultz also carries some and both can be found almost anyware.

That 18-18-20 seems like it would work.It seems like everybody uses somthing different.Its hard to recommend a specific kind ,This whole grow thing is alot of experimenting to see what works better. Higher nitrogen for veg and higher phos for flowering.
