Dolomite lime is helpful for balancing ph. I have added 1 tbsp to the top of my plants in 7g smart pots, then worked it into the top 2 inches before watering. Then fed with 6.3ph water my run off stays at 6.2 to 6.3
The lime also contains calcium and magnesium which are helpful for cannabis.
Its also inexpensive. You can pre mix it with your soil before planting for a better buffer throughout the grow.

Should I harvest in 2-3 weeks ?Hey, do you think my plants might be ready in two weeks ? They're autos in 7th week of their life. I know that 9 weeks is ok for most, but these should take approx. 11 weeks. Do you think one more week of feeding, then flush would be appropriate ? Trichomes are mostly milky white

I got to harvest in 14 days: in order to have enough time to cure it before leaving home for 2 weeks (safety first: is a period of floods in here, I just can't take the risk). I had a pretty long vegetative stage but I'm gonna finish it at 13 weeks. Am I gonna ruin it it, right?
