Ongoing brown and yellow patches forming in week 6 of flowerI've also noticed today a couple leaves looked wet, so tried to wipe it off but that did nothing. I took 2 pictures of the same leaf at slightly different angles to see the shine. It's only the skunk effected (closed similar question prematurely in skunks diary)6y ago

Die andere Pflanze hat diese Mängel aber nicht, beide wurden gleich gegossen, etc. Ich habe vor ein paar Tagen DolomitKalk und Worm Casting benutzt.6mo ago

Brown spot on leave. 6 weeks into flowering. -Temp 27'C day 25'C night- HD 65% day 75% night . Soil PH 6.5-7.00. Water always at 6.5-6.8ph.I just flush it 4 days ago because I think it got calmag lockout since I always give them around 5ml of calmag every watering. I only water when 2inch top soil dry with 1.5L of ph balance water. Not a fungus or anything that grow because It cannot be rub or remove from outside.Leaves. Color - Dark-brown

Possible P Deficiency?Hey everyone, hope all is well. I noticed these past few days some dark spots appearing on some of my higher leaves. From what I’ve read it looks like it could be a Phosphorus deficiency. Any ideas? It’s on two out of three plants of the same strain. All same feeding schedule.Leaves. Color - Dark-brown
