nute burn?

Hello everyone and thank you in advance for the help.
I have to what seems to be browning and yellowing of only the lower leaves.
I water about every 3-4 days and add nutes with the water every 2 or 3rd watering. I have these under 4 6500k CFLs. This problem started fairly recently and is progressing quite rapidly.

Thanks!

do you know what the soils ph is by chance? or the ph of the water you are feeding with?? and what is the PPM of the solution you are feeding?

I'm on the same page as Sampson, this to me looks like ph issue. Are you monitoring the ph or aware of what it is at now?

Yea, I would say check the PH balance and from 6.1-7.0 is a good PH am I right?

With over feeding you do not need to care about the ph level... bad ph level can be helpful at that time because the plants don't absorb as many nutrients as in a good ph level... The thing you need to control is EC-level, it measures the minerals in water... and thereby the amount of nutrients in the watter...

PH HAS NOTHING TO DO WITH THE NUTRITIONS IN THE SOIL!!! Youre case is clearly overfeeding your plants so they "burn" (we in belgium call it that way)
PH is responsible for how easy your plants can absorb nutritions !! So if u have a plant witch is LOW on nutritions in that case PH could be responsible...
In this case however having a bad PH would actually help u because the plant is overfed and burning itself, new nutritions would be slower taken from the soil.
What u need to do is give water then let the soil dry decent then again water,.... (NO ADDITIVES) for as long as the leaves of your plant don't start to look light green to you... (Now they are dark green = meaning full of nutritions) you can also monitor your additives level by using an EC-meter (measures electrical currency wich is affected by minerals in the water) so you can get an clear picture of just how many additives you give your plant... its far more complicated than this but if u simply not give to much additives and to much water (in beginning) plants should grow well
