Burn Or Def? quick diagnosis plz

well I know i burnt em couple days ago..but I just want to confirm that this is a burn and not a phosphorus def? (1st pic)
Plants just made 5wks today
Advanced Nutrients Conn A+B (Burnt them at 5ml A 5ml B)

Crazy I am using the same nutes and having the same problem

I am at week 6 and all of my fan leaves look like shit. I dropped my ppm way down to the 600s..

Looks like a slight cal def to me. Brown tips and spots are a give away. It's hard to tell because like you said, they are showing some nute burn too.

The begining of cal can look like the begining of burn. Burn usually makes the edges crispy. Cal always shows up as spots like that for me.

I shouldn't say def. it could be lock-out. Unless it's genetic, your stems shouldn't be purple or red. When I get purple stems like that it's from over feeding and lock-out. I'd keep feeding them at a lower ppm then you were.

heheh..squido my man..just the man I was hoping for a reply..
Yes i started giving them 2.5ml each of the base now and things seem to not be burning but Im still losing some leaves..either from yellow or they easily pull off with the smallest bit of discoloration
last 2 weeks ive been giving them 1ml of calmag added with the nutes to avoid calmag issues (hope i dont) atleast
And no clue what my ppms are still..never used the meter again after it read only 223ppms after i added 5ml each of base
someone said it must be out of whack *shrug

about how much mls(to the gallon) of base are u giving for the 600ppm? roughly

and squido..after i mix my nutes in my gallon bottle..and use only half..can i use the other half the next day? or just go fresh...i always do but im curious if im wasting my nutes discarding the rest down the drain
