Thanks guys. I got the female from a neighbor who said it was Old Timer Haze but I'm not sure the male was a Frost for sure. Aloha DB
Surely you mean to say this plant looks far too healthy to be good!
Mostlyme, Id hit your plants with a dose of Urea to stop the yellowing, and I did some googling just now and Urea is considered Organic, although some may disagree. It will also have the added benefit of lowering your media pH, which could be useful as organic media can often trend upwards in pH over time.
Ive used it multiple times in my garden for media pH control and its worked excellent for me at up to 100% Urea. Id feed at 150-200 ppm N to treat your problem. Maybe the 150 for the more sativa in your group.
Hi Dave,
I hesitate to disagree with an obviously very skilled and experienced grower like you, but I have a different diagnosis. I think my soil is too acidic. Nitrogen is absorbed best at pH 5.5-8.5, and I really don't think my (fresh) soil is above 8.5, while lower than 5.5 is a possibility: the manufacturer quotes pH 5.2-6.0 for the product.
To combat the problem, I watered with a suspension of lime and worm castings. The particles don't dissolve, but are small enough to penetrate the soils surfaces and distribute themselves throughout the container. This should help raising the pH towards an ideal 6.5.
Fingers crossed!
Haha Dave, looks like your plant changed it's mind about the sex it wants! Keep us posted, I wonder how this one turns out.
About the yellowing: I think the soil was too acidic to begin with, at least for my style of growing. I use RO water and never pH, so the only effect on soil pH comes from the nutes. As luck would have it, a typical nute solution comes out at about 6.4 - so pretty good.
As for watering, I would appreciate some advice. I normally aim to let the soil go almost completely dry, without plants wilting obviously. Would you recommend keeping moisture levels higher? Like watering when the top soil is dry up to 1-2 inches deep? (Yes, you can again praise your meter I have a tensiometer too actually, but it's too big for my current pot size).
TB, sorry to go off-topic like this, but I'm betting you are willing to allow it, as you probably want me grow good plants and gauge trip potential for you Which reminds me, I had some Destroyer the other day: it is has that delayed onset you were talking about, and the high comes in waves. It's early days, but this one has potential!

Dave, I already watered like you suggested. I watered in waves and well, and then waited until the pots felt dry. These wet-dry cycles, in my mind, helped to get lots of oxygen in the soil in between watering. It worked well for me working with hybrids - very nice root balls - but so so last round with mostly sativa's. So since I was having problems again, I began to wonder. I will water more often now.
In any case, the girls are doing well now. The yellowing isn't getting worse and new growth is healthy. They got flipped last Saturday, and exploded as you would expect for happy plants.
Here are close-ups of those very same foxtails:

The first picture is of a brownish red one. The second was in the middle of one of those fox-tails with all colors. The third one is from one of the tops of the ones that still have green at the top.
I was going to try and hold out until all pistils had died on this plant, but I'm losing confidence with this strategy. At one point there were buds that had a limey cat piss incense smell that reminded me of Thai Stick. A fox-tail from that bud is now taking on a menthol aroma.
I'm seriously considering harvesting half now, and the other half when all pistils die.
