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?

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.

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
