green around edges - slight curl see pic

I tried to focus as well as I could. Notice some light colors on edge of leaves, and slight curl to leaves. Specs. Strain XXX, 400 w hps, nutes fox farm, pH 6 - 6.5, temp 70 F., fan blowing 24/7. Water every 2-3 days, depending on moisture meter reading.

Any thoughts or are they OK. Other strain of Hindu Kush doing fabulous under exact same conditions. Thanks.

1. Stop feeding your plant
2. water every 5 days... but increase the amount you water your plant (at least 1/2 gallon)
3. Transplant to 3 gallon container with soil (70%)/ perlite (30%) mixture
4. ph your water to 6.5

That plant has a LOT of PROMISE... looks like it is an amazing INDICA.. great gentics... BUT you need to act NOW

you can save her!!

iloveyou
always saturate the SHIT outta of your plant.. and then let the soil dry for 5-10 days.... every 2-3 days is NOT correct

I don't grow in soil anymore, but does look like Ph prob. to me. I would do as Garden Knowm has stated. And plant looks very yummy!
