Spots on Leaves

[ChaoticGood]

Hi all,

I'm having trouble pinpointing the issue in the picture below.

Thoughts so far:

- Calcium Deficiency (or lockout)
- pH related nutrient lockout
- Magnesium...?

I'm going to give it some time to see if it resolves with the recent reservoir change, but thought I would try to get ahead of it. Hydroponic 5-gallon DWC with Botanicare nutrients (Pure Blend Pro) with Cal-mag.

Thank you,

Could we get a pic with light off please.

yup, need normal light pics plz,... that said, it looks Ca defc. likely,... what's the res' pH? Are you using Ca-Mg, and a Si supplement is really a good idea (not related to this directly), Si has several great benefits!

Thank you all.

Here are some pics with the plants out of the tent, i'm still not great. Yes, definitely using Cal-mag and silica blast is one of my favorite supplements ;-) pH anywhere between 6.0-6.3 - I did have pH issues earlier.

The last picture is blue amnesia auto XXL on the left and Girl Scout cookies auto on the right. I'm not positive, but it appears to me that the Girl Scout cookies auto growth has been stunted in some way ( at least compared to the blue amnesia)...

On the left is blue amnesia auto XXL and on the right is Girl Scout Cookies auto.

Hmm, well you got the supp's going- , pH is in good range for Ca uptake,... new pics help! I don't see the amount of spotting/mottling I thought I did,... are they progressing still or halted? Ca-Mg at full dosage? it'll take a couple days to get in there and halt,...

Thanks Waira. I ended up changing the reservoir for both and there seems to be some recovery. I may have stunted the Girl Scout Cookies, but we shall see. Keeping an eye on them for now to see how they recover.
