She's looking better, that "lime green" colour is ok. It should darken over time.
Is it the kind with 2 metal prongs that you stick in the soil? They give an estimation rather than an exact figure.
Have you a digital ph tester too?
Next watering I would give half strength nutes (ive never had to use calmag) @7 ph. And yes water close to the stem, the water will flow down with no need to get the soil at the edges wet (that would only slow down the soil drying).
Collect the water at the bottom and test that. Youll know then if you need to increase/decrease nutes or higher/lower the ph in your feeds.
With the holes in the sides your pots will drain better and more air will get to the roots. Solving your xxl pot problem

No its the single prong. I have reliable ph and ec pens from bluelab, costly items but look and feel pro. When i will switch to smaller pots, after this grow i could run off easier i guess and no need of prongs.
So half strenth nutes you mean like 0.6 ec per litre?
Woohoo my pots now are convertible mercedes driving around with blondies inside
