I measure the Ph of the water before feeding and the runoff water. I do this to ensure that the Ph is properly balanced. I use a BlueLab combo meter for measuring Ph and EC.
The reason I grow in soil mix is because it acts as a ph buffer
I’m not chasing Ph. I just figured I would provide as much information to help diagnose the plant. I use reverse osmosis water and monitor Ph. My question was not whether I had the correct Ph but whether this was early signs of nutrient burn and if I should back off on my feeding. The reason I do this because on my first grow I just added nutrients to the water but since my water I not at ph of 8 it drove down my ph and caused nutrient lockout. Since I started monitoring ph and ph my water all ph issues resolved.
But I'm telling you that controlling nutrients in soil is easier without changing the ph
I have been slowly increasing nutrients in fact I didn’t even give her nutrients until about 3 weeks into veg. I waited until my run off water EC dropped below 1.0 before beginning nutrients. I figured that she had used up a good portion of soil nutrients after that. I only feed her when EC of runoff drops below target level. I was just wondering if my target current target level of 1.7 is too high based off the light tip coloring. I will continue to Ph my water since I nearly killed my first plant when I didn’t.
