Hey, heres my setup
Soiless - Peatmoss/perlite/ewc
Flowering Week 5
Fox Farm nutrient line - Water ph'd to 5.3-6.0
1/2 nutrient strength
600 watt HPS - about 1.5 feet from the glass to bud
Room temp - 79-82 hum - 40-50%
-They have been slowly yellowing more and more over the past few weeks.
-The leaf tips are not brown or crispy but the leaves feel a little dry
-The other plant of the same strain is dark green, but also about 80% as big.
I have been reading up on this and I think I narrowed it down to 2 things.
Yellowing Between Leaf Veins
This is likely a potassium deficiency. Add to your water or correct a PH balance. Potassium can also be locked out by salt buildup so if your PH is correct you may try a flush before adjusting nutrients.
They both seem like they could be a possibility. Can anyone help?Leaves Turn Pale Yellow or White with Green Veins
This is a sign of iron deficiency. Add more trace nutrients or chelated iron. As always, PH imbalance could also be the culprit.
