Adding dolomite lime to already planted plants ?’s

Just transplanted about a week and a half a go 3 plants from 16 oz cups to 3 gallons of Fox Farm Ocean Forest. they were transplanted at 3 weeks from seed germination. A few days before transplanting the plants showed signs of a magnesium deficiency. It was assumed because they were rootbound but the problem persisted. Upon watering with ph 6.5 water the runoff was measured to be between 5.2 and 5.5. Obviously too low and could be the source of the problem.

Upon reading furthur FFOF apparently is notorious for ph fluctuations to the acidic side so dolomite lime is added to the soil and allowed to cook for a week before plants are planted in the soil. However, its too late since theyre already in their final homes. What is the best way to add dolomite lime at this point. Some say so sprinkle it on top of the soil and water it in. Others say to mix 1 tbs with a gallon of water and water in with the next watering.

Will theyre be any adverse effects of adding the dolomite lime while the plants are in the container? any suggestions to get this lime in the soil. If I do add it to the top of the soil and water it in should i flush more water thru perhaps 2 times the size of the container?

any quick ways to adjust the ph? Perhaps hydrated lime? Watering with basic water? the water watered with so far has been an even 6.5 pH just the runoff is way low.

Any advice is appreciated and thanks and stay safe all!

Dolomite Lime

I am about the flip the switch to 12/12 and have some beautiful girls going right now. 2 Lady Cane x DJ Blueberry, 1 Lady Cane, and 1 Kolossus. They are blowing up fast. I have had trouble with Ph of soil and coco in the past, so switched to hydro. Hydro went smooth, but I lost a lot of flavors and smells.

This time around I had a lockout for about a week in early veg, flushed them, and have been monitoring the runoff of the soil every watering since then, trying to keep it between 6.2 to 6.8. I had to start watering at about 8.2 and have been slowly working down, because the soil ph is starting to lower. I am now watering at a ph of 7. Since monitoring runoff, they are doing great. I just don’t want to keep changing the ph of the water if I don’t have to.

My question is. If I add Dolomite Lime, will I still be able to use nutrients throughout bloom? How much Lime should I use? I heard that adding lime can interfere with feeding them nutrients.

They are in 3 gallons of Roots Organic potting soil. I will be transplanting to 20 gallons of Roots Organics in Smart Pots. I want to use Roots Organics Buddha Bloom and Humboldt Ginormous.
