I was told not to worry about leaves at this point but they have to be an indication of something. Everyone says cal-mag but I tripled the Sensi cal dose to see no if it corrects it and it doesn’t. It’s happened on all three of my harvests so far. I’m at a loss because my ph is good and it shouldn’t be lockout. This is a purple haze auto so the purple is genetic but the spots are not

I’m thinking it’s calcium deficiency going by the spotting and leafs tacoing like it is. Too much calcium will lock out magnesium and potassium.

Yeah I know. Thing is it’s no good just throwing more calmag at the plant. Calcium excess will lock out other elements and cause further issues. Personally I’d flush with pH water and reset. I’d also be checking and re configuring my pH meter if it’s needed. I don’t trust this phPerfect bullshit. As the plant feeds and uptakes the elements it requires there is no way possible the pH will sit stable. You NEED a slight swing up and down within a range so all elements are useable by the plant. Calcium uptake is a requirement for the uptake of magnesium and potassium. If calcium is locked out so will mag and potassium.

I see the problem. Apparently there are lizards in my plant🦎 ! Nah it was only like 4 or 5 leaves that did it I just reset everything an my ppm is at 1150 ph at 6.2. And you’re right I still ph my ph perfect because it doesn’t always go stay where I want it.

In flower I aim for 6 to 6.2 in my rdwc to ensure optimal bud growth.
Just remember. Cannabis likes it slightly acidic. 6.5ph is neutral.
