So Here we go again. This seems to happen every time in my bloom cycle. The tips on the leaves start to burn and it gets progressively worse. I am worried that I have too much lime in my water and it is gradually raising the ph. I filled out the trouble shooting form below and also included some pics and the water report info from my municipal company. I did just deal with thrip, but it is now under controll with neem oil and nematodes. Any advice other that buying an R/O filter(that I can not afford right now) would be great.
- soilless in 5 gallon pots
- Roots Organic formula 707
- I have added nutrients and nematodes to the soil.
SCLR-Soil or slab runoff pH - Not sure and I want to get some advice before I water again to find out

Just tested the soil and it registered 7-7.5 I used on of the testers that comes with the color coded capsules..not sure how accurate this is.

Thanks for your help and let me know if you need ay more info.
