Deficiency on Leaves
ktkoi
started grow question 5y ago
What kind of deficiency causes small white spots on the leaves like this? Also on the lower leaf it's a bit mottled and yellow. I think it is two distinct problems.

Spots : Could it be bugs? Yellowing leaves : Make sure you don't over wet you soil. Don't water if the pot is still heavy.

Barney's Farm - Amnesia Lemon bad seedling?
My seedling is now 14 days since germination and planting in soil. I have the feeling that the growth is slow and the leaves are deformed. Should I start over? I'd rather try to save this one since I'm outdoors in north Europe and don't want to miss too much of the grow season.

Slight browning of upper mature leaves
Mid week 8 just noticed this color change on the ends of a few fan leaves near the top. It is only noticable on the upper most 4 mature fan leaves. Nothing on the new growth. Nothing on any lower leaves. Any ideas?

Whiteish damage
Anyone know what kind of damage this is or if its anything to worry about? A few spots like this on some leaves but not much. definitely doesnt look like mold or anything like that up close, its more like that part of the leaf has shrunken and whitened.

What are the brown/gold stripes from?
Does anyone know what this is? I am reading that it’s a Mag deficiency, but I did a reservoir change yesterday and put more CaliMag than last time, so I can’t see how that makes sense. PH is around the same, 6. I did add some PH Down directly to the reservoir, is that the issue?
