it is a good time to start fertilizing pkash and if you've already got those handy use the vigoro 19-6-12. it's higher in nitrogen,the first #, than the shultz 19-31-17, which is higher in phosphorous,the second#, and is usually used in the flowering phase,not the veg phase.start out using the fertilizer at 1/2 the amount the directionscall for,and only use it no more often than every other watering so you don't overfertilize.good luck,'Buz
