Yea looks like a calcium deficiency to me. U growing in coco?Im pretty sure it may be a calcium deficiency but im a first time grower so im not too sure, I pulled a leaf off and shot a pic, btw was using Jack's classic nutes in ffof bout 3 weeks into flowering wasnt usinf calmag til last week
She'll survive. My first grow I went through the whole grow with a un diagnosed cal mag problem. Nearly every leaf on most of the plants rusted and crispy, rusted and and fallin off lol. Still got a decent yield somehow.
they look 10 times better then my first runLol mine isn't at that level, its crazy how tough cannibis truly is. But thanks for the help here are some pics, the one with the light on are from today...the other is last week
they look 10 times better then my first run
Haha yea it does make it a bit easier. Il keep my eye out 4 itThanks man, you probably had to grow without the luxury of rollitup. It makes growing pretty easy as long as that person can read lol before I got on riu, I had no idea how complex it was. I would still be growing out clovers with an incandescent bulb lol thanks for the advice btw, I have a grow journal on it also if u want to see whats shes looking like down the road
be careful with calmag, if you only have a cal deficiency adding extra mag might make things work. If your not seeinging mag deficiencies I wouldn't supplement with cal mag, just cal.
How much calmag r u using and what's ur ph. The leaves that have been effected won't get better but u shouldn't be getting nemore rust on the ones that r still healthyPics
