how to safely add N during flowering

ok so I'm getting annoyed at my leaves turning yellow around week 4-6+ any advice on how to get green healthy growth all through flowering. iv been foiler feeding with grow for the past week in a hastey attempt to fix it but I have seen no differance yet,


what do you do

make some worm castings tea, and feed it to your plants.. i've been doing this in veg, and my plants have never looked more luscious green, ever.. amazing really.. i've also been foliar feeding them with worm poo too, but i don't recommend doing so in flower..

Add calcium and grow big with your watering. If the stem color is pale you need more N. if just the bottom fan leaves are turning you may have a nutrient uptake issue.

nutrient uptake issue hmmm

well maybe I should explain my setup first lol

master bubba kush grown in FFOF ueseing sensi bloom part a&b and bud candy I feed. every other watering and keep my water ph at 6.5

this is under a 1000w light and at 1200 ppm co2

Have you given it supplemental Calcium? The ph buffer process of FFOF takes away its natural secondary and micro nutrients.

Cal mag's a classic and I didnt see it on your list

I herd nit. Slows flowering fox farm says to use it for after 2 weeks after u switch to 12/12 cor a couple feedings then drop it after 4th week of flowering
