I cant say add more or less since I dont know anything bout the nutes you are using and dont want to steer you wrong. PH needs to be as close to 6.0 as you can get and what is the mix ratio of that stuff?? ml per gal?
yes the plant does need more than just nitro but since his plant is'nt uptaking nutes proper this has caused a drop in the nirto which is uptaken the most in growing/veggin plants.he needs a does of nitro for sure more so now.

mr grape you need to find something high in nitrogen to correct this or else it will get worse.but don't forget what i said above those need to be in ck or else you will run into this problem again.bat guano,micro and so on are sum things high in nitrogen.
