Can anyone help me diagnose whats wrong with these plants.
The two tall ones at the back are photos and had been going good until the leaves chlorosed and the other one has brown spots on some leaves.
Then the 3 autos to the front . The one to the right (gelato) is the healthiest very green and nice no complaints .
The one to the middle is the amnesia auto its leaves had yellowed severely lower down so I plucked them but the upper leaves have this brown orange tinge
The one to the right is on kush auto and its just yellowing.
I'm using the foxfarm cultivation Nation fertilizer . Veg for the photos and flower for the autos now.
I mix it just like they say ( which i personally find to be a very little when u work out 120g in 380L for the flower fertilizer say.
Feeding once per week
PH 7
Really want to save them and produce top shelf. I'm even keeping them in ac at 23 C degrees and have them in smart bags
