Just finished week 1 of flower and I have orange/rust colored spots forming on the upper/low leaves. I tested the Ph run-off on the last feed at 6.0 - Any suggestions or advice would be greatly appreciated. Spots formed overnight on only one plant.
Hey buddy!!! From the photos, I see that some leaves are claw-shaped, which is usually a warning of over-fertilization.. Try measuring the EC of the runoff water!!
Are you using tap water? Or filtered? If using tap are you letting it air out for 24 hrs to let the chlorine evaporate? If not you prob need to supplement your girls with some cal-mag if your not already. I personally got a carbon filter for my hose and drip lines. Works great to remove all the unwanted junk! Cheers and happy growing!
