Nope i wont give her More N you are using 3 products with N in it both sensi bloom and calmag too you are around 7 percent N , thats enough for that size of plant. Its normal that the newer grow is lighter, it will darken..... Iam using much less Nitrogen in that stage, The effects of Feeding N you see days up to one week later.. and to much is always to much and makes the plant sick, if you give less and older leaves start yellowing, you can react and give her a proper dosage, Not enough / of a slight defiency she can handle over weeks. But to much N makes her sick. happy growing
