Nitrogen Deficiency Question

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

Go ahead and give them some nitrogen.

During flower some yellowing is normal...its if too rapid then you could give a veg nute shot... Luck.

I think I'm going to give it a small dose of some 8-0-0 nutes and see what happens. It is slowly workign its way up the plant. not affecting any flowers yet, but just want to see if I can head it off since i'm only 4 weeks into flower. Thanks for the advice!

Ok, so I gave it the 8-0-0 yesterday and the plants seem to have enjoyed it. The leaves look better and I don't see any more signs that the yellowing is spreading. I think I'll give bloom nutes when it's time to feed again and just keep the veg stuff on the shelf unless it's needed again. Does anyone see a problem with this, or should I give one more shot of veg since some of the leaves are still yellow? Thanks!
