m0useanswered grow question 3 years ago Looking over your diary your CalMg is only 1ml/gal extra. nothing crazy and only for that one week.
If you where worried you could flush out your plant and just start over.
Regular dose is 2ml/Gal for that brand.
According to some feeding charts your PPM range should be looking in the 650-800 range for early veg and mid to late veg around 1050-1300
PPM is calculated in three different ways where as EC is just one value, convert ppm to ec - EC x 0.5 | EC x 0.64 | EC x 0.7 = ppm
https://manicbotanix.com/ec-to-ppm-conversion-chart-2/
This chart shows you the three reference points.
so 800ppm ranges from 1.2-1.6 EC
Hydro is new to me so use that information as you will. but that does not seem to be the problem.
Also Sensi grow has a lot of calcium in it as well. 15% in grow b's formula.
I think calmg might be over kill in this grow and not needed of if it is. at much much lower concentrations.

Your also under feeding with sensi grow. its advertised at 4ml/l in weeks 4 and 5 of veg.
Over all, drop the calmg and increase your seni, before feeding do a flush and clean out your medium.
But Im not that skilled in liquid nutes so double check my numbers.
Best of Luck.
