Do you find to saturate the fabric planters you need to use twice the amount of water to make sure the entiŕe root system get wet. If the brown spots are from the fabric planters, you know there are dry spots in the root zone
@GMSgrows, thanks for your feedback, temps been nice here so i reckon in my case it was excess humidity.
In terms of nutes i've used the monster mix from zamnesia, really happy with it so far.
@Reedius, i have the same brown spots on my outdoor but they were caused by excess cold here when they were first put out. Looks the same as my plants that had nutes coming out the sides of the planters from the fabric pots. Anyways your girls are looking good. Keep up the good work
@GMSgrows, It first appeared in the plastic pot and then in the fabric as well, I water them based on the their weight and they don't seem to have had any trouble with lack or excess water.
The substrate mix I made seems to infiltrate water nice and evenly so I don't think I have any dry spots, but upon harvest I will analyse both of their roots systems for differences.
Considering it's an outdoor grow and humidity has been high here I think it's perfectly normal for some of the older leaves to get a bit rusty.
Thanks for you input ;)
