It is a calcium / magnesium deficiency?
Hashyanswered grow question 4 years ago
I would lean more towards magnesium. Won't hurt it to add a cal mag supplement to your nute line. Other then that she doesn't look too bad.

I think it's the early stage of calcium deficiency. Increase the distance between the light and the seedlings and add calcium as well.

Are CBD-Strains less nutrient-hungry?Hey Guys, i experienced that these strains like a lower EC/TDS. Every time i went over 1.2 EC (600ppm TDS) they showed signs of over-nutrition, like very dark green leaves and reddish brown leavetips. What are your thoughts on this? Are CBD-Strains less hungry on nutrients?Week 13

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 help9 months ago

Insects, Mutation or related to my early nutrient burn ?Hey I noticed that one leave is looking like it has been eaten by something.. I checked every plant and also used yellow stickers, but can’t seem to find anything.
Is this related to insects or could it be something else ? (The plant had an early nutrient burn, but recovered)Leaves. Other

Stains on the plantHey guys,
first of all, thank you for taking the time to read this. I started growing my first canopy and since I am little excited, I started before everything I ordered arrived. For that reason, I am still using the soil I used while planting the seed. Did I fuck up already?Leaves. Other

Have you seen this and has it recovered?This plant was stunted at the start after he couldn't get his hat off, but now looks pretty healthy however it's been 3 days of just cotydelons and absolutely no sign of the first true leaves.
