Plants are 6 weeks old today. Ran into a little pH issue on this grow. I can no longer get bulk worm castings so am now growing in straight Pro Mix. That change has, of course, changed the pH of my base mix. Testing showed it to be at 6.5, and since this is soil less and that requires a slightly lower pH, I added some sulfur to lower the pH. I added a bit too much and my pH dropped to 5.2 - 5.4. I added 1/2 teaspoon of hydrated lime to the next feeding and that brought the pH back up to a good level, 5.8 - 6.2. Unfortunately by the time the change was effective the BB and PR were stunted. They have stopped their vertical growth at 10 and 12", so yield will be down on those. I'll be switching them over to flowering nutes on their next feeding.
Fortunately the SJs are still vegging and I got to them in time. They immediately responded to the pH adjustment and are back to growing strong, 1-2" of new growth a day. As of yesterday they were at 16 and 18". With about another 2 weeks of veg left I expect they should get at least 3' tall, which creates a head room issue. My vertical space is about 6' and they are in taller pots, so I'm going to run out of room. So yesterday I made a decision. They are two different phenos. The taller one is more of a single cola pheno so I've decided to LST it. The smaller one is bushier and has more side branching, so I topped that one. Hopefully this will allow me to keep a more even canopy top.
