I have 2 plants under a 150W HPS light in a rubbermaid closet grow. I switched to 12/12 on May 17 and the plants have done well, got some nice flowers forming. My problem is that I have a nitrogen deficiency problem (yellowing leaves, working its way up the plant slowly). I gave them no nutes during the veg stage and have been giving FoxFarms big bloom at 1/4 and 1/2 strength since we started to flower. I'm growing in soil which is a homemade mixture of peat moss, perlite and cow compost with a small amount of dolomitic lime. Anyway, my question is this...today is time for more nutes. Should I go and get a liquid nutrient that is higher in nitrogen just to kind of ward off the deficiency? Or should I just use the Big Bloom again as if nothing were wrong? If it helps, my plants are paradise seeds Wappa (which has the worst def) and nirvana ppp
