Your Fox Farm Ocean Forest (not ocean breeze / ocean spray) soil is EXTREMELY hot! It sounds like these babies went from neutral soil and no nutes to hot soil and overnuting all at once. Their roots are cooked.

Here's my advice to you:
1. You must flush. Read this sticky about flushing and follow the directions. http://boards.cannabis.com/plant-pro...ml#post1840641
2. DO NOT feed anything. Water only with pH adjusted water (correct range) until new growth looks normal. Then you can resume feeding at reduced levels. Work up slowly. Some nutrient feeding charts state feeding at the maximum rate! Just because the chart says it doesn't mean you shouldn't use less, just never more.
3. Fox Farms recommends that you feed with every other watering. In between, just pHed water.

MJ is picky about her pH and sensitive to overnuting. You must be more in control of your nutrients, water, pH. Practice getting the pH right. If you can't get your current tester to work you can get a digital pH meter for about $35, they are easier to work with.

The correct pH range for soil is 6.3 ~ 6.7. You adjust pH one time only after adding all nutes, etc., to your water. Also, each strain is different. That's one reason you see different symptoms on different plants. Only experience and research can help you with strain dependent issues.

Ventilation changes in your grow environment are needed. MJ must have fresh air to thrive and ventilation is key. A thermometer/hygrometer to measure temps and humidity is also a must. All too much to cover here, check out the forums for growroom designs.

You need to spend quality time reading the FAQs and stickies in the grow forums. They will explain everything you need to grow, harvest and cure MMJ.
