I always remove the lead weights and plant stems in small bunches, that way they have room to spread. Are you using any type of liquid co2 like excel, that might be why the vals are unhappy.
Probably took the plants 3 weeks to get to the point they are at now. tried to spread them out so they get plenty of light hitting all the leaves.What lights do you have (type of light and wattage)?
How long did it take for the plants to develop these problems (days, weeks, months?).
What fertilizers are you adding (how often, how much)?
Can you take more photos of the plants? I'd like to see the newer leaves of the stem plants, and please make sure the photos are right side up! It is difficult to see them without physically turning my monitor sideways.
Okay i will try uping the my nitrogen dosing to see if it works. My light is making the top of them look white, there more of a light green. I slowly acclimated my jungle vals to the flourish excel just for that reason. Thanks for the help.Hmm, quite possibly a nitrogen deficiency. The new leaves are stunted and the old leaves are deteriorating tip first. Look through my site for descriptions of deficiencies and pictures: www.DeficiencyFinder.com
The directions on the flourish ferts are intentionally very low, so you can easily overdose on them without raising nitrogen levels too high. Try adding 4 or 5x more nitrogen per dose and see if the plants start to recover. They should start recovering within a week if the issue is a lack of nitrogen.
Are the new leaves very white or is that just the photo you took?
As starfire12 mentioned excel does tend to harm vals. Though I have heard of people acclimatizing them to excel using very low doses so perhaps the excel is not related to the vals' appearance.
