[BIGGPOP]

One day Change, it seems like, I have a couple of issues,
looks like from what I have tried to figure out, magnesium deficiency, in the yellowing in the 1st picture, under watering in picture #2 and wind burn in # 3 not so sure how to correct. Only thing I did different was I turned one fan upward, I also had tips curling up, my temp range 68 low, sorry very hard to type for me. If I have lots of errors

78f high. Humidy has been low 37 to 40, just flipped to 12/12 today,

Which chart the sick leaf or the flowchart. Remember the last thing on the flow chart is if you canged something and problems start. first thing to do is put back whatever you changed.

Ok thanks it was like over night, can your ph change when its been sitting w/airerator running, that was something i normally dont do. Because i didnt check it before i used it last. Hmmmm!
i might have answered myself. Thanks for making me think more of what i did last.

[UrbZ]

Yes definitely.. if you normally let your nutes sit sealed or use right away the ph will be way different from one you've been pumping fresh o2 through. I am sure if it.
