Well are you refering to MG soil or nutes? I wanted to give the soil a try been feeding a couple plats 6.5 PH water and they look beautiful nice lush green color, been over 5 weeks just triggered them today actually. The nutes I'm not sure though dont believe it would have a dramatic PH change. What seems to be the problem mate?
thanks. its the water. i dont know..
my normal tap water comes in at 7.0 on the p.h scale.. but after ive added 1 scoop of miracle grow granuals to my normal tap water. and the p.h changes to 6.0, 6.4??
every different nute changes the ph in different ways, as the plant uses the water, the ph changes to.. may start off at 6 and rise to 7 as it gets close to needing water. dont use nutes every watering... but that depends on the nutes
Invest in some pH up and down because nuts most certainly can skew your pH ito dangerous territory. Or if you are on a budget steal some of your mom's vinegar and baking soda
ok cheers guys.. so my tap water comes in at 7.6 normall..
and when i add my miracle grow granuals.. (1 scoop per gallon) the p.h changes to 6.0 or 6.4.. i use a fresh water p.h colour card to test the ph and the and the drip thing??
Well it depends. Are you using a test kit? Or a meter? Or a soil pH kit? I'm assuming its a test kit which is for water. You want a hydroponic medium to be about 6 +or- about .3 (generally). Check out http://www.a1b2c3.com/drugs/mjgrow9f.htm for some basic info on cannabis pH
