What the hell is this?

MerionMatt · Feb 5, 2018

This is the same strain I've been growing for years and never have seen this before. The only thing that's different is I tried FFOF instead of roots organic this time. These are in veg about to switch to 12/12 and I can't figure it out.. it's not spider mites like other sites have suggested, I got the microscope out and everything is good. My humidity is a little low I'm like 76-78f and 40-50%RH and that's as good as I can get it.

Mg Def, did you just start using leds?

dubekoms · Feb 5, 2018

You feeding them anything? Need a whole plant picture in normal lighting if you want any real help.

MerionMatt · Feb 5, 2018

Yea they get calmag every feeding

. Is calmag not enough? I've used the same process every time only changed out different soils. Led always.

And all the essentials, maybe I need to up the dose on mag

Is there some major stem damage I can almost see in the pic?
Like from training or something?

MerionMatt · Feb 5, 2018

A few normal light pics

Yes this one I'm not tying down as much but I'd say pretty heavy training

looks like Mag. to me. what are you ph'ing at? have you checked your ph meter recently?

Nafydad420 · Feb 5, 2018

def a calcium deficiency.http://www.growweedeasy.com/calcium-deficiency-cannabis

yourlook · Feb 5, 2018

I am still on my first grow, but one of my plants had some cal/mag problems in the beginning that looked like yours. I too was/am using cal-mag, all I did was upped the dosage by 20-25% of what was recommended and raised the PH up a bit. It fixed the problem for me.

MerionMatt · Feb 6, 2018

I PH at 6-6.5

Roger A. Shrubber · Feb 6, 2018

i'd try 6.5-6.8, dropping below 6.5 isn't supposed to lock out Mag, but some plants are strange

@MerionMatt Ok from reading seems like you have the bases covered so I'm gonna say you have wind burn I could be wrong just a newbie on his 2nd and 3rd grow

And what else are you giving it? looks like a phosphorous deficiency to me

Tjs1989 · Feb 6, 2018

It looks like phosphorous deficiency to me as well.

Purple stems.
Dark color on older leaves w/
Bronze spots

MerionMatt · Feb 6, 2018

It got worse today and here's the other thing it's only on one plant, all the others are fine And all are same strain. So I use FF main three and have been for years. So now it's just big bloom and grow big. Do you think I should try adding some of the tiger bloom too for extra phosphate? Or should I go grab something more precise?

MerionMatt · Feb 6, 2018

Here's another plant that tied down but you can still see there's no rust looking marks
