Started 3 autos in 5g pots with ecothrive coco coir and 30% perlite.
Under viparspectra ks3000 24 inches away from plants and at 75%.
Plants are coming up to 3 weeks and have been fed with advanced nutrients sensi coco grow a and b.
Temps are 24c during the day and 19c at night, humidity is 60%.
Ec of nutes is 1.0 with ph fluctuating between 5.8 and 6.2. I've stuck to this ec and ph on other runs with success so don't think it's anything to do with the nutrients. I've done a run off test and ec is coming out at about 0.8 online with my previous successful grows. I even checked ph run off (i know i shouldn't) but even that is good at ph 6.0. Water is also left to sit for 24 hours heated to 19c with a ln aquarium heater and oxygenated before use.
The auto that seems like it has a deficiency is a critical kush auto. I've spoken with the people at advanced nutrients if it could be calcium and they said no with there sensi coco range it should have sufficient calcium. I had some Epson Salts at home so diluted a little in a litre of water and foliar sprayed just in case it's magnesium but does anyone think it could be calcium deficiency as that's all that is coming up when i search for rust spots, which is what it looks like but only info is when they are in flower and not 3 weeks old or in veg.
I've had this on other autos in the past using advanced nutrients so would be something i can hopefully solve as everything else I'm slowly getting right.
TIA and happy provide any further info needed.
