You have a ph in your substrate is off. You are in lock out on several nutritional needs. Run enough of correct ph water through soil till run off reads in range then replenish nutrition.

I'm thinking that there is a problem with yellow leaves.
I felt that the newly sprouted leaves just began to turn green and yellow. Is it a nutrient deficiency or ph? Cause , I only feed her with water and nutrient-dense water.😓

Leaves turning yellow and dying
I have a plant that gets a lot of rust spots, even though I give it CalMag once a week. That plant also started getting a handful of leaves that turn yellow and fall off. Is there a nutrient I'm missing in my regiment? Should I do CalMag every watering for the rust spots?

Older leaves are yellowing, brown/red rusty spots, dying tissue, red stems.
Older leaves have brown/red rusty spots and looks like dying tissue in between the veins. Burnt tips, and yellowing leaves. The soil was really dry and my PH meter was 0.4 too high. I gave each plant 3L of water with EC: 0.0 PH: 6.4 to check runoff. Runoff was PH: 6.1 EC: 0.8

Any ideas to what might be causing these leaves to yellow/die? Only reasons I can think of are nutrient lockout, having the lights too close (although I've heard with CFLs theres pretty much no such thing as too close) or possible having the heater running, or constant fan air

Im getting what looks like a Nitrogen deficency but I have put nutrients on my plants and still the same. What other thing can cause this? PH? All strains are 4 to 5 weeks old and already flowering. Yellowing started to show very early, since week 3 and leaves fall off.

Calcium Deficiency ?
Got a little deficiency, can't find what it exactly is. Maybe a cause of this problem is that they got 3 days of nonstop light because I fucked up with the timer just before leaving house for 3 days

Yellow leaves black tips
What’s happening with this plant? After watering all my plants 2 days ago, one of them has been quite droopy and developed these yellow areas with dark tips. Is it a watering issue / heat / deficiency? Thank you

Should I use distilled water instead of tap water and jus add nutes? I have a feeling my tap water is a little on the hard side 354ppms
Is distilled water better to use than tap water? My tap water reads 354 ppm, I have a feeling it's too hard so what I'm wondering is would I be better off using distilled and add nutes rather than using tap water? The pics ik I am feeding cal mag an some N next watering.

Yellow/burned tips & curled leaves
I have an issue with some yellow/burned tips and curled leaves. I already suspect that mainly is from light stress but could also be a nutrient deficiency? I´ve raised the lights the max I can and keep it at 80% for 20 hours. Biobizz soil and nutrients. Thanks in advance!

Yellowing, wilting, stunted growth
Can anyone please help me identify whats wrong with them. I've done a flush, adjusted the lights, reduced the nutrient strength, I've pretty much done everything and still stunted growth and they are still looking weak and frail. I'm lost and I don't even know what's wrong.
