Slight calcium deficiency. If it's on old growth and the new growth is fine. Then don't worry.

Calcium. By leaf look would guess overwatering, that swings pot ph .

I flushed it because some leaves were showing some Nitrogen Toxicity. Run off was coming at 3000ppm and I fixed it to 1500. Now the older fan leaves are yellowing with some brown spots (check the last picture). It's a deficiency? Should I increase nutes? Thank you very much!

Hello fellow experienced growers, is what I see on this leaf, combined with a reddening of leaf and main stems really signs of a CalMag deficency? Or do I have another problem? And is 1 ml CalMag Agent enough to counter it? Dont wanna risk anything so close to the goal...

So closing week 7 now and my 4AM are showing signs of deficiencies again. I watered(with nutes) ph'd around 7 past few times and the runoff has still been ~5.9, indicating acidic soil(nute lockout)?At this point, you think it's best I just flush with plain tap water(ph ~7.7)?

Day 14. Since day 12 a brown spot has appeared on one of the leaves of the first node, spreading little by little. Because of the symptoms, I think it's septoria, so I've sprayed neem oil to see how it works for her. Someone knows what can it be?

Some brown spots showing on the top sugar leaves. I suspect it is due to the cooling fan of the light blowing down hot air? I've adjusted the fans to blow air directly over the top of the main cola's and I increased the light distance.

When growing different strains in a RDWC system how do you balance plants with different nutrient needs. My amnesia auto ran into a major cal-mag issue and now is experiencing nitrogen toxicity, while my feminized Jack Herer's are largely unaffected. Thanks for the advice.
