how close is the thousand? looks like light burn combod with some sort of nutrient deficency, try putting a half dose of veg mix in with your next feeding... fox farm sucks, use coco fiber try royal gold basement mix or roots organic. my guy told me to put my hand in the middle of a palate of this stuff, it was hot, as in you could tell that it was alive, sooooo cool. why do i think its a light burn? after three weeks your plants have streached quite a bit and may have got into a very hot part of your room, (how hot is it in there anyway?) and yellowing like that is a sign of severe nitrogen defficency, or at leas it can affect a plant in that way....... hit me up if any of this helps... what nutes are u running right now?

This happened to my plants with my last grow and it has to be nutrient lockout due to ph problems get some lime from lowes or Home Depot that shit is cheap and will stable out your Ph....that's what I was wonderin'!
Im a lil confused on ph. Should I check it b4 I add nutes or after ? I have been checking ph, just before I add 1/2 strength nuts. How do I use that lime exactly? What is the ideal distance between light and plant tops? The temp is 75 the ph has been a about 6.0-7.0 approx.

...check pH after fertz., and just before you water your plants.

That is why I recently started growing hydro its so hard to have a exact understanding of what the ph is in the soil, you should check runoff and make sure its stable but that might not even be a accurate estimate of the ph in the soil. you can just mix the lime with your water, it just stays in your soil and keeps the ph balanced.

...from my experience, when you add the synthetic fertilizers into your soil, the soil buffers the salts, lowering your pH out of range...lime fights to keep your pH at 7, but....the synthetic fertilizers can be over powering the lime if you don't watch it.
...I'd suggest looking into organic teas while your in soil....works great!
...your soil's pH will also swing high as it dries, and will be lower the wetter it is.
