Anyone know what could be causing this?

Got some clones about a week ago and they are starting to turn yellow. I'm using cfls so i don't think it's from heat but idk?

What's the soil, do you check the ph of you water?

Ocean forest soil and I'm using tap water that I let sit for at least 24 hrs before using. I haven't checked the ph though.

ive seen it but didn't amount to anything in my case, hope it don't persist for ya

Looks like they have touched the bulb and got burnt to me

Yep...to close to the light

Idk guys the twisting leaves makes me think ph problems and I've also seen the discoloring on leaves identical to that cause by ph bein way off

The other option is potassium deficiency caused by the PH being off as mentioned above.

@vostok has a blog you would benefit from if it needs a flush

Your ph is too high. Tap water is usually 7.5+. Put a TBS of dolomite lime in your soil or ph down 5.8-6.3 range

Cool, thx. I didn't think it was the lights because the temps been mid to high 70's in my space and they haven't been too close to the lights. Time to check the ph I guess
