Hi All, could use some expert advice as I’ve begun to see some marks on my leaves as I continue into flowering. I am starting week 7 with 4 autos and am growing indoors in a 4x4 tent, 300W LED, daytime temp of 79 and nighttime of 73 and have humidity at 55%. I am using FFOF soil with a PH currently of 6.8 and am using the fox farm trio of nutes at 1/4 following their schedule - so just started to add in tiger bloom. I did do a flush for two waterings last week before adding in flowering nutes.
My initial reaction is the marks are from a calcium deficiency, but I am also using Cal Mag in my watering. The marks haven’t gone away and if anything I’ve seen more. I’d say the marks appear on less than 10% of my leaves.
Appreciate the advice!
