Outer edge of my leaves turning pale/light green on new leaves. Please help

I'm a first time grower and i'm doing hydro drip every 3 hours for 30 minutes. The outer edge of my leaves are tuning pale green. What shoud I do?

If you are sure your ph good(5.6-6.2), then your ppm maybe to low(low nitrogen).

Thanks for the quick response but I forgot to mention that I've been flowerinG for 25 days. I'll post up some pics when I get home. I've also taken 2 cuttings from the plant. One of them is under ghetto bubbleponics and another is on a pellet dipped in rooting powder.

If you are using only bloom nutes, then you are probably starving them of nitrogen. If not, then look into flushing to take care of any possible nute lockout.

okay so i changed the water last week and change my nutes to bloom nutes as directed.. changed watering cycle on my hydroponics to every 2 hours for 30 minutes and at night for every 4 hours.. my plant is now doing okay. new growth are green and healthy. unfortunately my clones died.. i have yet to master cloning.. lol. in the other hand.. i just got myself a seedling. it is now under my bubbleponics..
