Yellow spots and other questions - just started 12/12

Hi Everyone, I appreciate all your help so far (check here to see some older pics, and the history of the problems I've been having - https://www.rollitup.org/marijuana-plant-problems/337221-ph-problems-need-advice-pics.html - )

Anyway, the ph is well under control and I am adding Mg and Ca now and the leaves look a little better. I'm not sure what the spots are though...could this Mn (manganese) def? Man, I just don't understand why I can't seem to get this right on this plant...the other two I have are doing well and leaves are pretty much perfect.

Well, I put this plant into flower yesterday, she is about 20" tall right now and she is 16" from a 600w HPS. Is this too close? I hope everything turns out well, I included one profile pic of the lady so you guys could check her out.

Also in the first pic you will notice purple redness where the stem meets the leaf. The appearance of this coincides with the spots. The purpleness is also on the stems proper, but the stems are not totally purple, instead they have a purple streak on them.

I'd appreciate any answers questions or comments you guys have. Thanks as always!

looks like the start of mag def to me.

okay I will up the Mg a little more, I am just afraid of adding to much and getting Mn def (cause I hear Mg can lock out Mn)

Thanks!

It is mg and calcium deficiency to fix the mg problem just dissolve epsom salt in boiling water tablespoon to a gallong and water your plant with it also put some of it in a spray bottle and soak her the yellowing will stop and effected leaves that are real bad will fall of naturally or you can cut off if want to i just beat my mg deficiency hope this helps!

okay guys, I will amp up the dosage and let you know how it goes. I appreciate it.
