new to az and having some problems with my girls(space dawg)

feeding twice a day may be your problem. The "claw" leaf you are showing is a good sign that you are suffering nute burn. Depending on soil drainage, I would only feed everyother watering. watering twice a day seems a bit much as well, MJ likes to get a bit on the dry side before watering.

.

thank you for information. i"ve been wondering the same thing about watering too..

nute burn . just water for a few days. looks like your useing sunshine#4 soil. it has good drainage and already good for about 6 to 10 weeks of nutes in it so you have nute burn. water when barely damp. and because they looked stressed as well do you have white vinager. or do you use milk .. you may get molds in new plants if you over water them. and you can spray the top with white vinager/water or with milk/water on the plants or soil to kill it off. about a teaspoon per quart of water. works great if you see or smell a moldy condition. in arizona that shouldnt be a problem . but over water and over nute or nute burn can decreesed your plants resistance and increeses the posibility of molds and fungus.

also the temp meter you have also has humidity on it. i can see the temp probe on the left looks like the same i use. 40 to 60% is what plants like. there is a cheep way to put humidity in the space .
a small bucket of water and an small cheep air pump and air stone. just leave it on when conditions get to dry. below 35% and turn off at 55% ...

thank you all for the information.. i have add new pictures of my girls couple each day.. and input is welcome...
