A shot of cal/mg would do her some good. It's also high in nitrogen.

Light spots on leaves
I have some spotting starting on a few leaves. I had some slight tip burn last week I believe from letting the soil get too dry and getting a bit of nute burn. Two leaves showing these symptoms.

Deficiency and assimetric development

PH Fluctuations and/or Nutrient Issues?
I'm Running a Recirculating Deep Water Culture System( hydro). Had PH dropping dramatically a few days back but did a full water change and everything has stabilized. Just Flipped to a 12/12. Does it look like that was the issue or is it nutrient toxicity/deficiency. Or Stress?

Yellow spots on leaves
Are the yellowing spots signs of Leaf Septoria? I'm assuming it's more of a nutrients issue but have never experienced LS and wanted to get some second opinions.

Crispy Yellow Leaves
Inflow EC=1333 w/ PH=5.8 vs Runoff EC=658 w/ PH=6.0. Insufficient nutes due to light intensity? Perhaps my PH meter is inaccurate? Light is 42 inches from canopy or ~600 PPFD. RH 65%, Temp 80 F.

Intervenial chlorosis, thick wrinkled leaves. Ph imbalance or quantity of nutes? Will adding CaliMag back in help? Trying to avoid burnt tips issue
Hard water (7) lowered to 5.8. Last week: 1 gal 3 waterings, w FloraGro (2.5 ml), Micro (2 ml), Bloom (2.5 ml/), Hydroguard (2 ml). Last grow had burnt tips and possible N deficiency, so I was trying to avoid that. This week I've switched to GHE's schedule and added CaliMag.

Is this magnesium deficiency?
Organic grow. Noticed yesterday that my one girl has color fading from the fan leaves. I gave her 1 tsp of epsom salt per 1 gallon today and ph'd at 6.7. Was this the correct thing to do? Or should I adjust ph next time?
