White Widow: Spots appearing/worse now

[Watergunz]

@Waira She's not looking too bad. I'm thinking she was reacting in a bad way to the TechnaFlora nutrients (Nutrients too strong¿?)
She's currently at Ph 5.8 and is reacting well. The only down fall is, she doesn't like 1/2 strength nutrients right now.
She started to get yellow tips at 1/2
(If she looks weird it's cause I'm LST'ing her)

EDIT: Just noticed some more spotting, weird thing is I had flushed her for a full day and no more spots appeared, now that I used 1/4 strength after the flush adds spotting.

Flush- ..you're in DWC, right? How exactly did you do this? I'm not a hydro grower, but a plant on plain water alone will trigger other problems, and a day is plenty of time to cause them,... likely the spot spreading was is progress before you raise the nute's to 1/4 after that "flush".... stay below 1/2 strength if you're sure the yellow tips are from that feeding conc., and keep on the Ca-Mg.... pH is fine,... new pics show new symptoms, Ca is among them now (fine spotting)... Hammered leaves may continue to decline and crap out, which is pretty typical,.. no fixing damage done with these type issues... Watch the newer growth and maturing leaves for further symptoms... When was the last time you cleaned and calibrated your pH meter? Do you store it in the proper solution?

Yeah I am DWC. This is my 4th grow in this same setup, the only difference I can think of is in the water I'm using. I'm using purified water (PUR Water filer) instead of hard tap. The nutrients I'm using are the same as before, TechnaFlora nutrients.
I purchased a new ph meter early this month ( www.amazon.com/dp/B01GOL2U38/ref=cm_sw_r_sms_awd_x_79D7xbW1DKB8Q )
