I don't use liquid nutes so I'm not much help on that one. You should look into getting some good organic soil amendments that you can use to top dress with. They'll break down over time and feed your soil in turn feeding your plants. Then you wont have to worry about going out there all the time to feed with liquid nutes. Right now something high in nitrogen and calcium would be good to support veg growth. Alfalfa meal, bone meal, or lobster meal. Mix it in with some good compost or worm castings. Some kelp meal would be good as well. Based on your area Im guessing most strains will go into flower by end of July/ beginning of August. So beginning of July top dress again with something higher in phosphorous and potassium and lower on nitrogen for flower. High phosphorous bat or seabird guano or some fish bone meal would be good. When you go out to water your plants you could mix in some unsululfered black strap molasses, about a teaspoon per gallon. That will help feed the microbes in your soil in turn speeding up the breakdown of the soil amendments.
