Start of Week 5 :)
BM and SC are spot on flowering!
FLO's a little behind on that, but I'll take a risk here and say, she won't be ending up with that much flower anyway, so, no hurry :)
Noticed spots on SC fan leaf.
readjusted the light's distance and set intensity to 100%.
BM: 33cm
FLO: 12cm
SC: 37cm

SC and BM show signs of Calcium deficiency.
BM: 37cm
FLO: 14cm
SC: 50cm

almost end of week 5!
started to gradually lower rh over the next few days from 60% to 50%
adjusted the blumat on BM, soil seemed a bit too wet, the dropping leafs could have been an indicator for over watering ...
the spots on SC's leafs grew in size and numbers, kinda looks like calcium def. but given the soil mixture containing garden lime, that seems rather unlikely...
since SC shows clear signs of over fertilization, like clawing, my guess would be some other excess nutrient blocking cal uptake.
BM: 38cm
FLO: 14cm
SC: 53cm

Grow Questions
BobrMarleystarted grow question 3 days ago
Is this a calcium deficiency ? given the soil mixtures (recipes in germ. week) unlikely.
since they only get tap water, i checked the values
Ca2+ 65.6 mg/l
Mg2+ 17.3mg/l
that's an 3.8:1 ratio.
PH is 7.6, I never checked that tbh.
doesn't the soil compensate for that?

You have something going on here for some time. The entire plant looks yellow. Initially indicating a N deficiency. However, PH must be correct between 6-7, or everything else is a guess as to what is wrong. Trying to do a multiple correction is okay if you’re experienced, on the other hand it can surely kill the plant if guessing wrong. Whatever is yellow will not recover in this case. Try to save what is still green-ish. Correct your PH first, see if there is an N deficiency next and correct it. Be careful with your lights at this point, a burn will be easy.

A pH of 7.6 will make the calcium unavailable,............max 7.0 pH for soil.
Your plant also has a major phosphorous deficiency.
How can soil "compensate" for anything?

Some really bad chemsitry knowledge here. Cations do not readily bond with each other. They would repel each other. cations bond with anions, not each other and not when they are 100% disassociated in solution. They are in ionic form in that context. They would bond to different sites, not similar sites for the same reasons as why they don't readily bond with the same type of ion.
https://lawr.ucdavis.edu/classes/ssc219/biogeo/fig13.htm -- doesn't fully explain this specific thing but touches on enough relative topics.
beware of science lectures from someone with a terrence howard video professing that "1x1=2", and a bunch of other psuedo-science nonsense. the general answer might be right/memorized, but teh explanation is not accurate, lol.
