Look at this -- what is it? I had to post these pics because I never seen anything like it. Almost exactly 2 months grow under CFL. The banding is a very light yellow against the darker green vein areas only on new growth-- hard to see in pics. Looks like a trace mineral deficiency? Maybe Zinc? Older leaves are fine--look at first pic while still under the gro lights. Clearly the old leaf is fine and the newer one above is wrinkled and has the bands. You can see the veins are darker in the 2nd pic (WTF gro 4) in the new and maybe even the old leaves too!?! I'm FLUMMOXED! What do you think. He said the Ph was around 6.5-6.7 but the Ph test kit he has is somewhat inaccurate / high error. I thought a flush of salts in order? He been using schultz fertilizer 3/4 strength every watering for over a month. Waters every 2-3 days. I don't know. Just wanted to add that I searched books, online, forums, etc. for days! Cannot find anything on this. Other people have posted about "striped leaves" but have no wrinkling on either side of the stripes or else the whole leave is deformed and yellow etc. Never both together as in these leaves. Is this a unique problem? (maybe I can patent it! LOL) HELP if you can!
