Not an expert but kinda does look like some kinda fungus would treat with a fungicide
Here is a pic of a plant with rust I found in rollitup threads I goggled (rust fungus weed plants) and it was the first thing that came up
I have read that it is best to vent stright outside instead of dumping that air in the same room as your tent and using a second filter indoors. I would be taking advantage of that window and dumping your air outside
I have read this before and forgot about it thk you for the reminder. If that's the case then I already up my nutrient feed so I will back off on the cal/mag for now I know sound backwards if i think i got a cal/mag deficiency one thing at a time
My ppm of the tap water I use before adding anything to it is 150ppm thats after it sits out for a day or two.
I have started a foliar spry with cal/mag plus botanicare 1ml per litter ph to 6.3
Ok so just fed the two ladies. Up my nutrient leval to 2.0ml a litter and tested the ppm. My mix before watering sits at 590ppm. My run off is between 650 720ppm on two plants with soil ph at 6.4 and 6.5
Today is a feed day for the ladies I am at 1.5ml nutes at a litter of water. I am going to up bye 0.05ml bringing it to a total of 2.0ml a litter. will see this through will post pics in upcoming days weeks as I want to start budding soon
I started out with autos and the guy at the store said these nutes are good for auto so I always thought maybe only for auto as I could never find an answer to that question is it good line for all around growing.
I am using promix hp soil. My feed scheduled if this what you mean is water then feed then water and so on every 4to5 days I don't let them go past 5 days without water. As for my nutrient numbers I waited till plants where 3/4weeks old started my nutrient at 0.05 ml and every feed went up a bit...
