if you're going the organic way yes dolomite lime should do the trick, but I would suggest using GHE Ph Up, that way you water the plant until the runoff comes out between 6.0-6.5, this will give you faster results.

Yellowing sugar leaves!!
Hiya Folks 🌞 I've started to notice some of the tops have developed some yellowing on the sugar leaves tips and edges and I'm just wondering why this may be? Luckily she's nearing the finish line so I'm hopeful it's not too much of a problem?

Guys what’s the opinion on flawless finish for flushing. I have read on many forum sites that it does not do anything does anyone have any experience with such a solution. I have used it for the first week to flush the plants and I will use it for two days of the second week.

Is this a problem?
I have some old leaves with a reddish tint around the leaves, couldn't find any nutrient deficiency/excess that matches, maybe phosphorus?

Leaf Discolouration
I notice some leaves developing this yellow discoloration on the older growth, usually closer to the central stalk than the outside. The green gradually shifts to yellow going from mid leaf outward to the tip. I'm hoping it's just lack of sunlight from the dense foliage. Ideas?

Is this light burn?
All my leaf tips are going yellow, even on the bud leaves. It does seem to be a bit worse towards the top of the plant. Is this light burn? I am using 2x 1000w philzon LEDs in a 3.5'x3.5' Tent and I had them at 10/10 brightness. I just reduced to 8/10. Thanks in advance
