Hello everyone i am currently week 7 of veg in my first organic grow. I am running build a soil 3.0 soil and just a few days ago gave them a top dress of craft blend with a little bit of big 6 in the watering(1tsp in a 5gal bucket) but ive noticed this plant is getting yellowing from the tip of the leaves and its going down the edges as well. Being my first shot at organics i was wondering what this might be and possibly a way to fix it ? Thank you for any input, also its been doing this for a few weeks now not since the top dress

7.2 pH is a bit high which is most likely why you're seeing problems.
use earth juice or something simular to lower the ph
7.2 can also start locking out nutri
Ive done nothing but living soil also and i add cal/mag twice during the grow,it doesnt killoff anything imho
My ph is around 7.2 but im growing in living soil so i cant really add bottled cal mag. I have run bottles up to this point and im making the switch to living soil to try it out. Alot of people say good things about that style of growing, its just getting use to it on my end
looks like Mag deficiency but its in the upper leaves..maybe nit tox..whats you ph?..have you fed any cal-mag?
