Yep the Plants took off as soon as your Balanced things out by hitting it with more A&B.
The CalMag you have is too heavy in "N"4-0-0 is pretty hot for Cal Mag..Better to source some with 2-0-0 or better yet 1-0-0
Most Calmag formula's 1ml per liter is all that you need if using RO water. 0.5 ml for Tap Water.
2ml per liter when Buffereing A Coco Substrate
What you had was either Calcium Toxic or Mag Def & Phos Def caused by too much Calcium and basically bugger else because your A&B was too low.
Seedling only require a low EC 0.6, nothing wrong with upping that to 1.0 or 1.2 EC. It wont burn them but it does ensure they are Getting everything they require from day 1.
If you want to run a low E.C. then its paramount to get the Balance right. Personally I don't run anything less than 1.0 EC unless flushing at the end
1,5 ml per liter minimum of A&B Any lower and you will not have a balanced Nutrient
Take a look at your Feed Pie Chart in week 4, thats where your Plants went ohhh Fuck this shit I aint Drinking Jack shit till he fixes it...lol
