Leaf Discoloration

[h4ppyf4rmer]

I saw this on one of my plants in a 6 bucket rdwc system.
18/6 lighting, 24" over plants,
ec .950,
pH 5.9,
water temp 73.
Using Gh floraseries 1:1:1 ratio.
I have .5 ec water so I have not used any cal/mag supplement.
Any idea?

Hi mate, not sure if this is of any relevance but my tap water is also 0.5.ec.. my ladies still need extra cal mag and react well to it...
You can request a breakdown of exactly what's in your water from your supplier so you can really dial in your feeds... especially for rdwc I would think!! Good luck

Thanks, I'm not overly concerned as the rest of the plants in the system look fine. I'll probably order some cal/mag just in case it gets worse. It does appear to be a Mag deficiency as the leaf is an older lower leaf. This is my first time using clones for the grow. Things are definitely different then growing from seed...
