The damaged growth will not repair its self.
Will need to pluck that off and monitor the other leaves to confirm its fixed/corrected.
As for how much CaMg you need, monitor your EC and keep it inline with what the plants are comfortable with. It will take up close to 1/2-1/3 your EC allowance. Will only need a heavy feeding at beginning to correct the issue then can tapper off into standard/lower ranges of concentration, some bottles have directions for how much, I find it's still best to use EC and go from there as they all suggest over feeding so you use more and then buy more.
Good Luck!

EC .2-.3 of cal-mag is a good starting point.
It is also dependent on your water, how much calcium/mag is in your base nutrients, and how much base nutrients you use.
With botanicare nutrients I aim for 140-160 PPMs ( EC .3) with my water + cal-mag.

Growth looks like it's stopped, is it time to flush?2 of my plants look like they've stopped growing now and the calcium deficiency looks worse and worse.. should I just flush then with water for a couple of week and be done with them?
The late bloomer looks like it's got ages still, definitely not what I'd hoped for being autos

Looking for clarification on the Flush time required for a RDWC grow? I have read this can be as little as 2 days of just plain water but should this also include CalMag if I am RO water? I assume the standard root rot treatment continues? i.e. OxyPlus, HydroGuard, Phytoff?Thanks4 years ago

Drainage issueI'm not quite sure why this cup doesn't absorb its waterings when the other two solo cups are getting Watered every day. All 3 cups have no drainage. They are all grown in the same conditions.
My first instinct is lack of drainage, do I need to make some holes, bottom or side?
