Been growing with 50:50 blend of ocean forest and promix with lime added for nearly a decade and always very pleased. Not lately. The ocean forest is damn near toxic even when blended with promix. Roots down really want to travel much In it and are underdeveloped. Almost two months in 3 Gallon pots and they just keep burning and burning and exhibiting strange symptoms I’ve never saw. Usually I would have been fertilizing a month ago but have used just straight water this time. They should be so deficient that they’re dead by now but no and no signs that the soil will every run out of whatever is devastating the plants. Two plants in just promix are doing great with great root development. A friend who purchased ocean forest a month after me from a different store in different city is experiencing same issues. Also a seasoned grower. What is up with quality control?! I’m not gonna bother with flush as they’re 4 weeks into flower now. I triggered flower assuming that they couldn’t just get burnt and stressed for all of eternity from a watered down ocean forest that’s blended with promix but wrong. My mistake there. Perhaps when the plants harvest their pathetic yield I’ll use the soil to feed an entire forest of trees but it’ll probably burn up acres of them as well. Horrible soil and I can’t trust them anymore. It’s sad really.

To keep ph in check. It’s something I’ve always done out of habit and it’s seemed to work very well. I know someone’s the ph can vary in bags and can drop over time…especially during a longer cycle.
Do you know what lime is for? It raises pH which means you likely raised pH past 7 and locked out nutrients.

I always used lime out of habit in my Pro Mix. Didn't know if it really helped or not. This year I forgot it and my plants were sickly and my runoff ph was very low. A little lime rarely hurts anything imo.

Lime refers to calcium carbonate. This tends to stop adding too much alkalinity. Past about 7 it is inactive. Makes it the near-perfect acidity control.
Yes but it should be a calculated amount based upon a soil test/reading, otherwise your run the risk of locking out all available nutrients
There is calcitic lime and dolomitic lime, which is not calcitic, so not all calcium carbonate. You can 100% over lime a soil waaaayyyy past 7. Should never add lime without confirming the need for it.

If I'm not mistaken...
They actually are all Calcium Carbonate. One just has additional Magnesium Carbonate

If you buy a bag of dolomitic lime it has both whereas calcitic lime does not have any mg.
