Hello! By light problems do you mean excessive intensity? Quite possible. I think additional food for the growing season can solve this problem; you can also raise the lamp a little.

Yes, I mean excessive light intensity. If that's the case, it's kind of crazy: I've got my light about 2 feet above my plants and it's at 50% power (65 watts). I fed the plant with dry nutrients on 9/30... You think I should use the liquid as well?

Nice if this is ace Panama it's fire. .i've flipped some .are your lights at 18 or 24 7?

It IS Ace's. Both lights are 18 on right now.

Taking the advice of @rindindoo, I've given the GG #4 clone it's first liquid nutrient feeding with a 1/8 of a cap (1/2 tsp.) dose. I trained the MN Tangie mother a bit. Later today, I'll also give everyone molasses water, save for the clones in the party cups.

Continuing to see lighter colors in the new growth on the GG #4:

Called 2 grow stores and they brought up potential issues:
  • The light isn't strong enough.
Out of concern of roasting young plants, my light is about 2 ft away and at 50% power. After talking with one of the grow store employees, I'm convinced it's safe to increase the strength, so it's now at 70%.
  • It could be nutrient-starved.
For those keeping up with my journal, I'm running what I was told was a nutrient-rich medium (Buildasoil's 3.0) and have given the plant its first dry and liquid feedings. They could still be becoming bioavailable at this point.
  • It could be rootbound.
I have no idea. What do you think?
  • I could be watering too much.
Definitely could be the case. I've been watering pretty much daily, based on the first knuckle finger test.

I looked closely at the photo of your clone, and it seems to me that it doesn't look like its roots are flooded. the turgor of the leaves looks normal, if the plant were flooded then the turgor of the leaves would be weak, the leaves would be drooping, and yes, with chronic overwatering, anaerobic bacteria begin to develop in the substrate, the pH goes into an acidic reaction (due to rotting) and blocking (absorption) of nutrients therefore yellowing of the leaves occurs. But again, I don't think you have an overwatering problem. To eliminate the possibility of overwatering, skip one watering and test the pot by weight before and after watering, then you won’t have to poke your fingers into the ground :)
Lower the lamp 1-1.5 feet, and feed with half the recommended dose of your fertilizer. It is also important to remember that on peat substrates the plant’s response to fertilizer application is much slower than on coco. Therefore, I recommend gradually increasing the concentration of fertilizers to avoid overdose.
Can you give me a link to your fertilizers, I’m interested in reading about them.

I've skipped watering today! I JUST increased the light intensity to 70% yesterday. Am I in danger of killing my little Panama clone (and maybe MN Tangie and Blueberry F5s soon) if I expose them to that much light?

Here are my fertilizers:
