@Neal1239 I would start out With Half a dose as @Hellraiser mentioned. You can always add more later After you see how your plants respond. Good luck. ---

You can buy a conductivity standard solution. To verify your PPM meter. As far as the fox farm chart and product I have never used it. So I would not be the one To give you the best info. There are several community members here that use the product. ---

Most TDS meters are set up for 500 scale. FF uses the 700 scale. Some meters have a setting to switch to the 700 scale. If not, here’s a conversion chart ![55EF5CFF-CDCC-4EED-AF02-450401E8593A](https://global.discourse-cdn.com/growingmarijuana/original/3X/d/9/d9532199d7acdd42b21a905b1b945679826a91f0.jpeg) here is a FF chart concerted to the 500 scale. I think I got it from bobbydigital but not real sure. ![35A17306-1ADF-49DE-BDF2-7EE8D0878CC0](https://global.discourse-cdn.com/growingmarijuana/original/3X/6/6/66e53de17dc738c6e5afc5e28e034b4de553c4f8.jpeg) I hope that helps ✌💚 ---

I’m glad I could help. Thats the schedule I use. Your meters manual should say what scale it’s on. I have an apera meter. I watched several you tube videos to figure mine out. [Previous page](https://ilgmforum.com/t/why-are-my-auto-flower-leaves-turning-yellow/42491.md?page=1)
