Yellow centre veins fan leaves
Yellowing of the inner vein of fan leaves only. Also sporadic yellowing and blemishes of whole fan leaves but only some, others fine nice and green. All bud leaves and buds don't appear affected. Is it just that she's nearing the end of her life cycle? Or over water/over nute?

Leaves with yellow spots
We have find some leaves with yellow spots in them. The tips on new leaves are also turning yellow. Is this nutrient burn? Searching online I found it may be due to pH fluctuations, although we use pH controller with ferts (before ferts only bottled water pH ~5.5).

Yellowing a bit too soon
During the second week, leaves started to look a little bit yellow. The first true leaves yellowed way too soon. I'm guessing lack of nutrients. It never showed signs of drought or overwater stress. Your thoughts? I planted it into larger 2.5 liter container now.

Nutrient lockout? [first grow]
My plant’s started showing signs of nutrient burn, so I have flushed them with just water, after 1 day they turned to worse condition than before. Is it nutrient lockout? Or just deficient? Appreciate every feedback!

Magnesium nutrient lock out, triggered by too much potassium ?
@Burmese Thank you so much for your help. 🙏😊 I think it was a magnesium nutrient lock out, triggered by too much potassium. I sprayed some water with Epsom salt on the leaves and it looks like it is getting better. 👍😉
