What can I do about the nitrogen toxicity?

This one is about a week or two younger than the other two

Also what can I do for nitrogen toxicity? Is it the tap water im using?

If you take pictures of the nodes close up I can help you confirm sex if you want. Your plants are starting to exhibit signs of nitrogen toxicity. Shiny leaves, deep green, and clawing, especially on the one in the bottom of this photo. I saw you ask for advice in your other posts but had noting to contribute at at that time. I don't tend to give advice that isn't asked for but considering your other posts asking for advice went without being answered I figured I'd do so now.

You might want to consider consolidating your posts as well. It makes it easier to track information. If you edit your original post it won't update to the top of the queue so you have to add new information as comments. If it's a different topic then new threads are the way to go.
