I'm 21 days into Veg, 9 26 watt CFLs, 6 65K, 3 27K, soil from the florist, havn't tested PH, have de-chlorinated water, 2 days ago I noticed 1 of my plants had some yellowing on a fan leaf (I have 3 plants, femmed bubblicious) so I thought cause this soil I got is mixed at the florist and doesn't have nutes and stuff in it that It may be a nute deficiency so yesterday I fed them 1/4 strength Jacks All Purpose veg nutes. Now another plant has some yellowing of some lower fan leaves. Now i havn't ph tested or ph treated my water, and I suspect this may be the problem, and no matter what I hear from ppl, in the morning i'm getting test strips and PH up and PH down. Is this my problem, or is it something else? I can't post a pic that is up to this minute accurate, but this is a pic I took 5 hours ago of one of the girls, the 2 that have the yellowing have this look pretty much the same, but it's spread to a few more leaves, and is a bit more widespread,, but only on the lower branches. In this pic you can see the yellowing at about 1 o'clock

Here's a good thread on diagnosing problems based on the leaves... and it has pix too 8)

I used soil and water that I didn't test the pH in for my first several grows and it didn't cause any major problems (just low yield and sub-par bud). Florist soil might have nutrients added, so I would stay away from any added nutes--no nutes are better than too many nutes! I don't know for a fact if they do or don't, but my logic tells me they might. A florist needs as many flowers as they can get. If they're transplanting a bush for flowering, the soil might have added nutrients to help this growth.

In the morning, in addition to buy a water pH kit, also find a soil test kit. Figure out what the NPK values are because you will add nutes based on the soil ratios. You want the N levels to be high during veg and low during flower. If your soil has a high N value, do not add any more nutes that contain this since you probably have more than enough and you could be adding more than the plants can handle.

ETA: I bring up all the N stuff because it looks like a nitrogen problem to me.
