Please Help

I have a problem...All of my fan leafs are drooping on one of my better looking plants. I don't have pics, so I understand it will be hard to say definitively what the problem is. I thought perhaps that the roots were being constricted by the size of the pot. Got a new pot...transplanted. When I did I noticed that the roots hadn't really gone all the way down, let alone restricted growth. So please any suggestions on where I should go next would be greatly appreciated.

Do you ph test? Are you giving ferts? If so what kind and what strength? What temp is your grow area? What kind of light are you using? How far away is it from your plant? Do you use a moisture meter?

yeah all very good questions in order to better help you. how old are they?

I actualy came up with a cheap moisture read for myself. I use wooden BBQ skewers ( like 2.00 for 50) and I stick them in the edge of the pot to about midway or so and then I can read from the moisture on the stick about where I am at. Mind you it is not an exact science but it gives me some insight . This coupled with getting a feel for your plants when the are dry and a feel for when the are watered realy helps. Also journal everything you do so you can easily look back and unlock any riddles when you have problems.

good luck my friend I know what you are going through.
