PH levels for the effect on yield

[kneegrow]

I know this may seem a silly question to some but i've literally jut bought a PH pen after a year or not using ph indicators at all, Now from what i see it is 5.5-6.2 for coco soil, I'm just wondering if PH levels make a massive difference for yield or is it just that there is less chance of deficiencies?

thanks guys

Well, when you use the correct PH plants grow more healthy, faster and better. Correct ph helps to better absorb nutrients. You also can check at forum, this information here is.
