Not light stress, but the beginning of magnesium deficiency. Giving cal/mag will solve this and prevent it from getting too much worse.

Did i flushed too early??
Hello guys i began to flush the roots, is it too early? May i feed them one more time? I care about different maturations, maybe the yellow one will need nutriments to continue??? Should i defoliate a maximum ? I surely did the mistake to follow the 6-8 weeks on zamnesia.com....

When to start nutes
Anyone have any tips on when to start nutes on this girl? Her bottom single leaf is yellowing a bit and one or two other lower leaves have a yellow mottled coloring. Not sure if that’s from touching the soil due to LST or because she’s hungry. This is supposedly a low nute strain

Leaves browning in multiple spots Lower leaves yellowing but have green veins.
One plants leaves are browning in multiple locations. I attempted to diagnose the problem with runoff tests. pH was 6.5 and TDS was around 900ppm, which was expected since they received nutes that day. Despite not spreading to other nearby plants, could it be leaf septoria?

Lower big leaves coming yellow and curling down ?
The lower big leaves are coming yellow, and curling down and looked like "overwatered" but i dont think it is. Maybe nitrogen deficiency ? or too hot ? could be a pH problem ?

What are optimal PPFD
Anyone have a quick and easy rule/suggestion for PPFD & lux for plants in Seedling, Vegetative & Flowering states? Lots of divergent answers online. At plant top right now I'm currently at ~1000PPFD and the lux readings are 49,000-51,000. What are 'best practices' for this?
