If you had leaves wet under light, possibly lightburn.

I'd guess a calcium and/or magnesium deficiency

Yellowing on leaves tips. Should I start feeding her?
Some yellowing appeared on the leaves this last day. Temps and humidity are controlled and ok. I haven't been feeding her, she has been growing on light mix for the past 25 days. Im thinking its time to start applying some nutes. Or could be something else? Thanks!

Leaves dying
Last week I noticed that the leaves were starting to burn on the tips and added a question here. Most ppl said I should give less nutrients so I started giving only 800ppm (I was giving them 1000). Today I noticed that the leaves were like this.

Magnesium Deficiency ? How can I fix it ?
got a little deficiency (maybe burned? but I think not). I'm pretty sure it's magnesium's deficiency, it happens after a flushing. I added 2 times the last 2 weeks a little bit of CalMag (BioBizz, but ive bought it 2 years ago, maybe it doesn't work well idk).

Yellowing of the leaves under the main canopy?
Hey I’m wondering what could be the cause of this. They went 8 days between watering so, Is this a deficiency or due to under watering? Should I trim the yellow leaves or leave it? Thanks

Veg Nute Issues
Has anyone seen any diaries that catalog a successful sick veg -> healthy flower recovery? I'm curious to see how sick growth transitions to healthy growth over several weeks. Current issue: a) LED intensity, b), N excess, c) PK def, or d) cal/mag def(rust on leaves top and btm)?

Brown spots and yellow tips in flower, started around wk 8-9. Thanks!
My 10wk old Auto Trainwreck started showing brown spots and yellow tips @ wk 8-9 but even after up'ing Calmag to each water wk 8 (1tsp/gal) it's everywhere now. It's been 75-50% the whole time- deficiency in late flower? Again big THX to the community - for more than just this.
