Good evening everyone,

I'm in a bit (a lot) of trouble here. I'm currently growing a White Widow (not an auto) feminized in DWC.

Currently using filtered tap water.
Ph level is sitting at 6.0
I'm using Technaflora nutrients/ feed chart. This would have been the 2nd and 3rd week of nutrients at 2/4 strength instead it's 2nd and half the 3rd week.
From the advice I was given, I was told my issue was a Cal Mag issue to Up the Cal Mag to full strength @2.5ml each gallon (12.5ml total)

When following the advice my plant now looks like this right now

It's getting worse and the issue seems to start from the bottom and is making its way up.


Any idea what's going on ?

Thank you!

Boron/calcium deficiency - fixed by feeding with mineral potted plant feed, super cheap stuff, just check the back of the bottle for the relevant elements, usually theyre called "balsams"...
 
Awesome guys thank you so much, I was completely clueless. I haven't ran into this issue before.
Thank you again!

I get this problem in soil when I introduce calmag too early it causes a lockout, and the only way I've found to fix it for me is to dissolve Epsom salt in my feed water, but I don't know if that's OK to do in a hydro setup
 
:toke: WGz-- pardon mate, this one slipped by me! :doh:
... Ok, I'm not following what you said about your nutrient dilution and schedule,... you're doing 1/2 recommended strength? Not an auto, so why the dilution? What's the ppm in your rez'? We need to figure out if you had a brief pH snafu, causing a temporary lockout (reactions in hydro are very fast), or if they're just lacking, simple defc.,... the symptoms look more like a P defc. than Ca, though both can cause those broader necrotic patches,.. Ca usually has some, to lots of finer spotting associated with it,... Also, I think your pH is too high, which can mess with P uptake...get it down to 5.7.... How's she looking now?
