Need some help with PH in soil

[pbull79]

Im running Roots Organic 707 and the roots line of nutrients. My last few grows have ended with a nutrient lock (start seeing signs around week 3 to 5). I haven't had these issues before. My soil PH has been between 8 and 9 on these grows. I ph my water between 5.8 and 6.2. I'm top feeding and I'm wondering if I'm not watering enough. Should I be watering until I get some runoff?

That's a rich soil.. you could get away with a grow without feeding till flower with that soil. a soil pH of 8-9 is way too high. Dump that soil and start all over or remix it with some compost and fresh soil if you want to use it again... but really don't need to feed in it as it's a really rich soil. Your wanting a soil pH between 6-7.. adjusting the waters pH won't help. The soil will just buffer it back up.

If you want to keep the soil.. don't know your pot size there, flush out all the feed you added to it by watering three times the volume of the pot. You definitely have a lock out.
