Problem: My leaves are curling up and the stalk is turning purple. Any ideas? Wow, the template nailed it... Also having rust spots on a different plant which is not experiencing curling.

Note to Growers: We ask that all growers who learn from us, give back by helping other growers, when the time comes.

Thank you in advance for any and all help.

The leafs lighter green looks like a Mag deficiency...since you're growing in coco, are you using a cal-mag supplement? it's recommended to use a cal-mag supplement like Botanicare Cal-Mag+ or General Hydroponics Cali-Magic when growing in coco or using RO water.

The leaf tip looks like pH issue, and you can get the brown/rust spots from pH being off, make sure your pH meter is correct. Another than that she looks lush.

I've read his logs and watched his videos He has some great stuff, im following his watering schedule and mixing. I am currently using 3-4 ml calmag per gal.

I bought another PH meter and it was saying my old one was a full 1.3 off, maybe thats it.
