Is this rust need help

[jonadamcaldwell]

Does anyone know what this spots are? This is a white widow autoflower in DWC, it is about 18 days old and these spots are working there way up the plant taking over. I have changed my water and I am using GH 3 part system with cal mag, for each gallon I added 1/4 tsp of micro, grow bloom and 1/2 tsp cal mag. The water was ph at 5.7 but does drift up pretty quick. At first I thought I had a cal defenincy but seems to be getting worse. I started to think it was rust so I got some sulfer based spray called Defender and this also is not helping. Any suggestions? Oh and I have a northern lights in soil rite becide the white widow and has no issues as of yet

no silly thats a phosphorus deficiency

remember, autos are flowering on day 1, dont feed them like they are in veg. i do 1 part bloom 2 part veg at the start of their main growth.

Thank you so much, this is my first time and it's turning out to be allot harder than I thought. I am having a hard time trying to find a guide line on the bites for autos, do you have any suggestions?

Yep Click Here

That plus knowing that auto's are a cross of indica,sativa and Ruderallis, a non THC containing russian marijuana plant that gives it the auto traits.

this is why autos will ALWAYS be lower thc than the high end non autos.

As soon as your baby auto wakes up, it starts flowering, its stretch starts as soon as it has leaves to power the growth.

Ok thanks, I just flushed tonight with fresh ph water I will add some. Utes in the morning. I can't seem to find anything on the amounts of nutes for an auto

amount of nutes depend on size of plant. learn your plant and listen to her.
