hi...i'm gonna try and make this succint. we are using a stick meter for soil getting a reading of 6.9. we use a chemical test for watering that reads my tap at 6.7. i tested my ferts (MG-it's all i could get) yesterday and they brought the tap down to 6.2 some of the stems on my 1.5 week old seedlings are partially purple. none are completely purple and no leaves have purple veins. it is bag seed. my questions are 1. am i going to see nute lock with a soil ph 1/10 over optimal range? 2. do meter sticks for soil tend to run low or high? (like, HOW crappy are they?) 3. can i just count on the fertilizer bringing the soil down to where it needs to be? 4. could the purple at all just be normal for now? thanks!!
