You need calmag, I imagine. Or you have a severe lack of micronutrients like iron, sulfur, etc.

Yellow lines on 2 leavesAny clue what this is? About to be week 6 and in flower. I'm thinking the start of nute burn? I gave it bloom boost in the last 3 waterings in less and less amounts. let the soil get very dry before watering with plain 6.2 pH water. Any input is appreciated

If my ppm intake is about the same as my ppm runoff but my pH runoff is way lower than intake should I be worried? Or what should I do?If my ppm intake(705) is right about the same as my ppm runoff(790) but my pH intake(6.7) is off from my pH runoff(5.9) should I be worried or be trying to correct something or should it be fine?

Leaves turning light green -- yellow (after 12h day/night rhythm)Since I started with 12h daylight/dark rhythm a lot of leaves started to turn yellow (older and lower ones first, some branches turned red). What I did:
PH value=6.5. I added CalMag--no effect. I flushed the soil --no effect. Do you have any ideas? Thx green thumb-friends 👏

Nitrogen toxicity or deficiency? Or just PH issue?Hi buds.
Gonna need your expertisè again. My Grandaddy Purple auto is showing signs of something.
Leaf claw: N-toxicity or PH issue
Leaves fading: N-deficiency or PH issue
What do you think changed this one leaf, and what do you think is going on with the other leaves?

leaf yellowingI have a problem with yellowing leaves. Yellowing appears immediately after germination. And it continues until harvest. I thought it was the fertilizers. Fertilizers that are old. I threw away the old fertilizers and bought new ones. But the problem still persists.

Brown spots on top leaves - nutrients, light or something else?She went into flower, now stretching. Set light to 100%, added Bio-Bizz Top-Max and Bio-Bloom (1ml/L each).
3 days later brown spots appeared on top fan leaves, very few also on lower fan leaves.
I suspect this could be light burn or nutrient related.
Any ideas? Pls help
