Hello, i am having a few issues and wondering if anyone knows what it could be.

I feed once a day for now with 20% runoff
Im in a 5ft by 5ft by 7ft tent with a 6in exaust fan and 4in inlet fan using spider farmer sf4000 about 20in away

I just started the calmag yesterday, could it be a cal or mag deficiency?

I'd guess cal/mag if it was just introduced yesterday. You should not see those rust marks expanding. CHeers mate, gl!
 
pH of your water?? Looks like a lock out of some sort NOT Mg maybe Ca. Dial in your water pH if you're using tap water let it sit out overnight and/or add in a touch of Vitamin C (ascorbic acid) and check your pH. Vitamin C will help with the Chlorine if you're using tap water.

Looks like a water issue to me.

Start thinking about putting them into flower. Those plants are going to get large. VERY large.

Whats the source of the seeds??
 
I think i solved the issue, cal deficiency. Im not seeing any progression, last grow i used 1ml per gallon of calimagic with mc, i was trying to use only mc, but dont think thats happening with this strain. Ph is 5.9 right now and runoff ppm is the same going in so no build up. Thanks for the comments everyone
