What is your growing medium? If you’re growing in soil I highly doubt it’s a cal/mag issue as there is plenty of cal/mag for a grow in most quality soils, more likely you’re Experiencing pH fluctuations in your medium.

Vague, though I would probably use calmag...but then, I'd probably also add a bit of sulphur and phosphorus if I have some.

1.0 ml of calmag per 1lt will do it wonders for next week or 2. Then start lowering it 👍🏻🌱❤️🍁

Purp stalks, weak leaves.
Hey guys i noticed that my stalks were all turning purple and my leaves are curling. Is this a nute lock out ? Or is it light burn ? I started them under a pretty powerful Led but still getting new growth through the last 2 days. They look thirsty but medium is still soaked.

Leaf burnt edges
One leaf has burnt edges and is a little different looking, than the other leaves. Is this some kind of nutrient burn? I am using a light mix soil, and have not fed the plant with additional nutrients, except for a little root stimulant (half of recommenced dosage).

Discoloration and patches on the top sugar leaves
Leaves circled have gone lime green to yellow with the dark and light spots shown in the image. Is it light burn, wind burn or something more sinister?!

What to do? Leaves are getting worse.
Had some light strain earlier on, but now im leaning toward a deficiency. Been feeding on a low-dose flora series schedule with clean ph water for every other feed. Just had clean water yesterday and nutes 3 days before. Dry out between feeds. Nitrogen? Calmag? Other?

Defficiency or light burn?
I Had this on my previous plants, I'm starting to think it is light related as it seems to happen to the leaves closest to my mars hydro. I wonder what would be the best course of action here? Ive added a tiny dose of calmag, can I supercrop this late into flower?

Epsom salt as fertilizer. Whats your take on this folks?
Epsom salt will not release hydrogen ions in water so my guess is that it will thus not affect PH. Making it a nice controllable source of Mg that would be not negligible right? How effective would that be to treat Mg deficiencies? Anyone has experience with this?

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? 😡
