nute deficiency maybe. got any pics?, how are u growing? what r u using 4 nutes?, do u know the Ph level? how old r they?, r u still in veg state, or flower?
I didn't see curling leafs,everything looks pretty good by the looks of the pic,but if you say your leafs are curling it could be your temps,or your light could be too close to the tops.Are they curling upwards???
Edited,I guess I wrote when you posted that pic......looks like lack of light,but they look healthy
Yellowing can be from lack of light,that pic is from the bottom of the plant right,the light does not penetrate to lower foliage and can cause yellowing....what ppms you running??
got a good amount of that curling under and inward yellowing and then darker ends misshapen deformed leaves will put up better pix 2morrow. their healthy close but not perfect looking 4 advice what way 2 go. my yeilds been way low 2 ant tips welcomed

You will get better yield with hydro as long as you keep ideal conditions....sometimes my plants get those curled leafs under the canopy and look slightly yellow......but it's no big deal,if start discoloring, start falling off,and starts working upwards,then it's is a deficiency or excess depending on symptom.....but they really look fine.
For vegetative stage I use botanicare pure blend pro grow +liquid Karma + Cal mag since I use ro water.For flowering I use pure blend pro bloom + liquid karma + cal mag + Humboldt's own Purple Max Snowstorm + Humboldt's own Gravity.
looks nice my cheese turned purple like that at the end week 8. hows ur yeild? i had good quality and low yeild like a half o from each plant in 1 gal soil containers. these r my first in hydro using diffrent strains flowering moms and just starting to flower hydro looking more promising than last run at this point. im using nutri plus line and just added some high p-k not sure numbers now....to the mothers wich are in week 4 im using a little fox farm big bloom in both
I yield 1-2 ounces per plant depending on strain I scrog with a plastic net,I veg for about a month or so.....
It's a strain I got from a friend who breeds,smells and taste very grapey.......I don't know why the mishapen leafs I get that on lower branches that don't get much light,I usually cut that all off before I throw them into flower those shoots are really just a waste of energy the plant could be using focusing on the top colas.
