Just checking is this calcium def? pic inc.

She's a WW in DWC, all environmental conditions are fine, but has what looks like to me a calcium def. Just thought I'd get a 2nd opinion.

Res is 5.8ph, 50l made up of 40l RO water 10l tap (our tap water has ec of 0.4, thought that would give me enough calcium/mag and other crap).

I'm using Dutch Pro A+B EC at 1.5, res temps 19deg, tent temps 68-75, week 5 of veg, 300w led.

Looks like it to me. if your using RO you might as well spend the extra money on some calmag.

I think I would try going 100% RO water with cal/mag added. The calcium in tap water isn't always in the best form for plants to use.

Cheers guys, yeah I had some AN Micro left over (basically calmag it'll do till I can get some) and threw in 100ppm of that yesterday, she started to stink again when I checked this morning (sign of a happy plant lol).
