Winter grow

[Hondo4921]

Hey folks. Got 2 plants goin, a couple free seeds. Both in 3 gallon fabric pots with Fox Farm happy frog under a mars hydro tsl2000. The bigger plant has some spots and looks to have a little yellow showing up between the veins. Using regular tap water that I gas out for 24 hrs at least. Haven't been checking ph, been lazy with this grow cuz just seeing what I can do during the winter. Thought I was over watering at first but I don't think that's the issue now. Haven't given nutes yet either. Did some super cropping 2 weeks ago. Been going ok. Temps are on the cool side around 68 F. Any thoughts would be appreciated. Thanks.

To me it looks like the larger one is starving.
I would start using nutrients on her soon

Looks like ph fluctuations.

Start giving them some nutes and check your ph, has alot to do with what it will intake the most

CalMag and PH the water - guessing it is on the high side.

Thanks everyone for the responses. Will have to get a ph pen so I can do this the right way.
