Hi everyone, I’m hoping someone can help shed some light on some problems showing up on my vegging plants.
Medium: coco/perlite 90/10
Strains: Early lemon berry RBX and Critical 2.0
Lights: 250watt custom LED panel
Temp: 25c day / 22c night
RH: 55 - 65%
Nutrients: Mega solutions 3 part mineral / cal mag / silicon / amino acids boost
PH at roots: 5.5 - 5.8
PH: 5.8 - 6.0
Some plants were exhibiting rusty like spots and leaf tips, randomly appearing on new and old growth. Also, a lot of the fan leaf stems are going quite a bright red / purple.
I was feeding at an EC of 0.9 and was worried of nutrient lockout. So I flushed them with ph’ed filtered water.
The symptoms were still spreading slowly so I upped the EC to 1.0.
The plants are starting to look lime green on the new growth and the symptoms are not stopping.
The plants are still growing vigorously. Clones, 36 days from cutting.
I’m unsure if I need to be upping the EC or if there may be something else at play.
Any help would be greatly appreciated!
