Watermelon (mystery bag seed)

The leaves are starting to turn yellow on the two more productive plants. The buds are getting bigger, but the question now is, how big? I don't really have a macro lens or a jewelers loupe so it's going to be a guessing game for me, I'll just have to squint real hard to see how much amber is present in the trichomes. Growth has been pretty slow with these plants, probably due to the low light conditions. I wouldn't be surprised if these plants had another 3 or 4 weeks left in them before harvest... I've noticed that some of the very white pistils are slowly starting to turn orange, I'm not sure if this is an indicator of progress but it's a noteworthy observation. Also, the second most productive plant, (which looks to have undergone quite a lot of stress during growth, including some nutrient deficiencies), has started to show some signs of color in the bud areas, the stems are quite purple in places, but now the leaves near the buds are also starting to turn purple which is quite interesting. Mutant number one, which has throughout the grow been more healthy than its deformed sister is growing nice little buds, not super productive but lots of frost on there, in the future I would cull this one, the amount of bud it has produced really isn't worth the effort of growing it. Finally, the mutant has popped pistils! it looks like there probably won't be anything worth smoking to harvest from it, but the fact that It managed to flower at all is a success in my eyes. It has been interesting to watch it develop, in spite of its horrible deformities.
