Long story short I am 2/3 of the way through my first grow and am having a huge problem with my Fox Farm Ocean Forest soil being too acidic. I am getting runoff PH of 5.5. I had to do a 15 gallon flush to get it to a runoff PH of 6.2. Today I watered with 2 more tablespoons of dolomite lime (for a t…

I know every thing that I have harvested (autos so far) most of the upper leaves are in pretty rough shape by the time I cut her down. Browned out and dry. Do what you can to see it through.

Do you think this is from the light? Dbrn32 thought perhaps my light was too close but I am at the recommended 18" from top of plant. I am afraid if I raise it my lower buds won’t get enough light.

Don’t be pissed at the soil. This far in, most mediums start to acidify. That pH that is guaranteed is its starting pH. After months of growing, microbes and chemical processes tend to acidify the soil. I recommend slurry testing.

No, I was talking about tap water. I respect that everyone on here has some valuable experience they are willing to share with the rest of us. However, the general consensus is that it is not possible to accurately PH tap water. I can put my digital PH tester into tap water and get a reading but I h…

I am about to create a new post regarding a reply I got from Fox Farm customer service. I will tag you. I did do a slurry test. Results are in this post. They were not good. PH 5.3.

@smokysmurf that’s my grow. It was 90 gallon but between 9 plants. It took the better part of the day. For what it’s worth, after the flush; I have seen EXPLOSIVE growth. They are 17 days old today and I’m happy. They just got their first haircut this morning. [image] [image] [image] [image]

That is incorrect info. Distilled and RO, yes. Not tap water. There is no arguing about this fact. :grinning:

Can I accurately test new soil to see what the runoff PH is?
