two plants three weeks into flowering. using technaflora nutes 2/3 strength. add cal-mag every other feeding. ph is set at 5.9 and the temp is about 80. can anyone tell me if its a nitrogen deficiency or something else? or how i might go about correcting it. thanks.
My issue was too dry, low humidity. Sprayed them with some water and they felt better an hour later, i then turn off dehumitifer and new growth was not affected. Dehydrated leaves
That looks like their over fed to me and your temps are a little high.
Are you soil or hydro?
Eventho you using 3/4 strength fert, your probably feeding them too often.
