I'm 5 weeks into flower. My top fan leaves are turning brown and lower leaves are lime green and falling off. I is r/o water at about 1 to 5ppm and growing in coco coir. I took one of the leaves into my hydro guy and he said light burn. So I turned my two 600w hps down to 50% but didn't help. Now that I've read about r/o and coco. I need to put in extra cal mag. I was wondering if I should do a flush with just cal mag or just add it to my nutrients and just feed like normal? I have advanced nutrients cal mag bloom so there is not a much nitrogen.
And an I us as a spray too? Is there any way to give them a boost of the cal mag? I think they need more calcium then magnesium or I would put some Epsom salt on top of the coco. By the way I use all advanced nutrients from connoisseur all the way up. My last grow did the same thing but 10 times worse. This is only my 2nd grow.![image.jpg](/data/attachments/2034/2034766-9044b37f5aee8eac80d2734b3e076f48.jpg)
