No problem at all my friend. Like @Emilya was saying, if your ph comes out in the end to be 5.8 you can absolutely not raise the ph. The only difference will be in the nutrient uptake. I run mine constantly at 5.7-5.8 and have never had a ph problem. Like i said earlier i will be going a bit lower and higher to make sure my plants can absorb all the nutrients that are in my growing medium.Mind if I pull up a chair
The post above from @Emilya is really interesting I also grow in Promix and always thought the correct ph was in the 6.2-6.3 range and that's what I have done for my last grow and my current one. I run advanced nutrients and after I add my nutrients my ph is 5.8 Im excited about the possibility of not having to add any ph up any more if im understanding correctly. Is there any harm in changing this mid grow?
Didn't want to ask a question about my grow in your journal twnewell but this is a very interesting read
