Carencia de Mg
Hojas en forma de bandera con manchas amarillas, sin dudas carencia de Mg, el problema es que no se que lo provoca, haré un estudio de acidez al suelo para estar seguro, pero dejo el hilo abierto a cultivadores más experimentados por si me podrían dar una mano con esto

Deficiencies while in late flowering during flushing period
There is deficiency going on (looks like cal) she is an auto flowering strain in her 9th week and been flushed for a week now. Should I give her cal/mag and stop the flushing or is it too late to deal with that? She looks like she will be ready to chop in a week or so.

First time DWC, day 70, 3 weeks in flower. Nasty rusty spots appear on lower leaves. Is this CalMag or else? Please help understand and fix, thank you :)
I'm using TA Tripart, current EC is 1.6 - ph 5.5-6.5. Everything was smooth until week 10. Two weeks ago I started adding Plagron Power Buds and Green Sensation. Yesterday added CalMag to see if it helps, but it doesnt seem to... She drinks a lot, ph mostly goes down, EC static

Hello fellow experienced growers, is what I see on this leaf, combined with a reddening of leaf and main stems really signs of a CalMag deficency? Or do I have another problem? And is 1 ml CalMag Agent enough to counter it? Dont wanna risk anything so close to the goal...

Day 4, after emerging. Is this coloration on the cotyledons okay?
Humidity is 55 - 70, temp is around 20-24c, 50w full spec led It's my first time, and i think i have been watering it too much I also fed it 2-0-0 npk water with 4ml per liter and I since learned it's not okay. Will it recover? Is this too little grow for day 4?

Two problems in a week. I diagnosed the first one based on similar grow questions (: maybe not right )
First three photos appeared a week ago, I decided that it is calcium and took a more reliable Ph meter, maybe not right, but no new spots appeared. Second problem at the end of the week, 3 days after defoliation 2 large lower leaves and 2 leaves inside. 30 hours after watering.
