It's a Calcium/ Magnesium deficiency, for some reason plants under LED lights crave more Cal-Mag.

CalMag during a flush?
I was wondering whether or not I should keep feeding CalMag while flushing the plants. I've read a lot about the flushing process but since CalMag is not considered a fertilizer, I am not sure how to handle the deficiency at the end of the grow. Any tips? Thank you guys!

Organic dry amendment replacement for bottled cal-mag nutes? (Preferably off-the-shelf)
I always seems to run into calcium issues (rusting and interveinal chlorosis) around wk 4. While early use of bottled cal-mag (TPS, "organic") has worked very well, I'd like to be able to simply add an additional organic dry amendment in my line-up vice bottled nutes. Any ideas?

pH is 5.5 but i have nutrients deficiency. Can it be the cold?
One of my plants (in soil) has yellow leaves and brown spots, it is possible that it lacks Ca and Mg, but it's pH is 5.5. I wonder if this nutrient deficiency is caused by cold water (now I'm using it warm and waiting), low temperature or high humidity.

Rust spots on leaves, second grow and need some confirmation.
I'm noticing rust spots on my leaves, which I suspect could be due to nutrient burn or lockout, given the PPM is unusually high for this stage of growth. To tackle this, I'm planning a simple flush with some Cal-Mag, keeping the pH at 6.5. Does this sound like the right approach?

Late Stage Nutrient Issues?
As the plants near the end (last two weeks) should I expect to lose virtually all the larger/medium fan leaves as the plants drain them of nutrients or is that a sign of overall nutrient deficiency?

LSD Auto BarneysFarm is showing nutrient deficiency. I need some help to get this girl unstressed.
I'm using BioBizz LightMix with the BioTabs Starter Kit in 25L pots (prepared the medium from the beginning with 3 biotabs). I have three girls where 2 of them are running healthy, only the LSD Auto is making trouble. How can I fix the problem which you can see on the image?

Rusty spots on fan leaves overnight, what is it? ️
Last night I used some old but clean looking wire to bring branches in to the main stems. This morning there's now little orange rusty spots everywhere. Is a soil grow, 6.3 pH used and same run off with Cal Mag every other feed. Taken the wire of at 6am in anger, was it that? 😡
