Promise I'll get fully acquainted here directly.

Problems getting a little worse. Can anyone suggest what is going on? Black spot seemed to develop instantly.

1st pic there are 3 things: white spots (pointed at), a black spot to the right, and brown spots up top

2nd pic - brown spots in focus

3rd - opposite side of plant, damage @ tips

4th - those are holes, middle and right leaf.

5th - black spot in focus

6/7 - bigger pics

info:
400w mh @ 21 inches
78f room temp
67f rez temp
5.8ph
General Hydroponics nutes
FloraGro 63ml FloraMicro 38ml FloraBloom 13ml
Have not yet introduced co2 (sparkling water)
this is a clone from a friend - been in bubbler for a week (i have progress pics but the damage is mostly recent)
roots still not thru the netpot.
the bottom left fan leaf in pic 6 has yellowed the most, started at the tip and got worse.

As a side question - this is my first bucket setup - I noticed alot of sediment from the expanded clay pellets at the bottom. Should I freshen up another bucket at this point or is the sediment ok until my first changeout? I planned on letting it ride another week before change.

I'd actually like to know what causes the holes I have two leaves that are just growing in. One has these smalle holes that are in that fourth picture.
