If really low on funds you can use Dyna Gro foliage pro start to finish. You have a ton of options to choose from. Telling what kind of soil are you using might help you get more through answers.
with that soil you shouldnt need nutrients for at least 3 weeks,but koolbloom for flower fox 3 part trio is pretty good to,i dont even feed nutes in veg,just water and tea,i made my on soil though
i highly doubt this guy is coming back or trusts anything anyone says on this forum after being trolled yesterday ... but for what its worth i agree Fox Farms trio is good thats what i use its not cheap tho i think i paid 70$ for the 3-pack of 32 ounce bottles , also ull need cal mag
i grow in soil and i would just go with FloraNova Grow and Bloom It is a one part and works very well in soil from start to finish IMO best bang for your buck
