I dont think there was ever anything wrong. As plants get bigger and rate of growth is faster, newer growth will start paler in color and darken up as it matures. You can see that happening. Multiple lights with different spectrums can exaggerate this effect. Just my opinion.

You have one of a few problems...ph imbalance can block out ur nutes or slow uptake of certain ones depending on the imbalance of your ph, too high or too low, shoot for 6.5. Over fertilizing can shut down nutrient uptake altogether and cause curled over leaves as can over water. With out magnesium as said...your plants can not properly perform photosynthesis. It's not considered a macro nutrient but do not under estimate it's importance! Looks like ph or over water.

My leaves are turning a light green color. This is mostly happening to the topmost leaves but on a couple plants it goes down further. It is only happening to a few of my plants and they are all in the same room with no difference in light, nutes, water.
They are in pro mix,perlite, sand mix and are about 12-14 inches from my 600w mh with air cooled hoods. They are about 5 weeks old. I have ruled out overwatering(I let them dry right out) and too close to the lights. Temps are good, 75-80 day and 70-75 night. Hope this is enough info. Thanks
They look quite a bit lighter than pics show. Also one pic is of healthy plants

I would still check your overwatering dude. Those leaves look plump and heavy. Stick your finger all the way into the soil and wait to water until its almost dry. Whats your pH? this is more important than what nutes you have it on? Soil is 6.8 ideal

Oh, and you added lime but not Sulfur (epsom salt). This could make your pH very basic and lock out Sulfur. (again, check your pH)

For living soil the salt will also kill most of what you've worked to create in the soil altogether

How close are your lights? What are you feeding them? Soil Ph?

I’ve manage to sort it I think it was a nitrogen dEficiency I’ve started using canna mono nut for the deficiency and they are look a lot more Normal now getting colour back. I’m just using bat guano and tap water I know it’s not ph perfect and the light are about a metre from the plants I’m not sure the ph of the soil but I’m using is called plant magic in a black bag
