older darker leaves and newer lighter lime green leaves - week 5 of flower
    #714402 - 02/12/14 11:20 AM (2 years, 8 months ago)

so this has been goin on for the past week or 2. the older lower leaves are a dark green, pretty much what the plant should look like, but all the newer growth is a lighter lime green color. it appears the edges of those leaves are slightly darker than the inside lime color.

the weird thing is, i bought 4 clones of the same strain at one time from a dispensary. 2 plants are identical and the other 2 are identical, so im wondering if i got 2 different CCK phenos. all 4 have gotten the same level nutrients. 2 are bigger and 2 are smaller.

Kind of sounds like a zinc deficiency, also kinda sounds like its nothing at all.

If your older leaves were REALLY dark you may have just had too much nitrogen and now its evened out.  I can kinda see that your leaves were clawing, also a possible sign of too much nitrogen

In my opinion those bottom leaves are too dark. I agree, too much Nitrogen. It likely won't be a problem if you just lay off the nitrogen and let it even out.
In soil be careful with Nitrogen supplicants because some N supplicants need to be processed by the bacteria in the soil to be absorbed by a plant. This bacteria need one carbon molecule for every N moecule they process. In other words, adding too much Nitrogen can burn out the carbon in the soil. Once the carbon is gone the soil won't be able to hang on the many anions. Your plants will need them.
I suggest giving plants a source of carbon every time one gives them a source of Nitrogen. Carbon can be delivered by manure, straw, or some sought of other mulch.
