My plants seem to be off the rails for their last weeks alive .
I posted in my thread .
I don't think what my plants are doing is light related . It is happening to lower leaves .
I did turn two of my lights to 80% instead of raising them .
Is what you saw happening at top of canopy ?
I also would not worry a whole lot about leaf condition over buds in final weeks .
I may be wrong ,I asked for help or input in my thread .
Love to learn .
Strong believer in cutting during the hottest part of day ,if outdoors preferably 3 days of hot sun .
Pics? It is normal for plants to use mobile nutrients from lower leaves upward near the end of flowering, especially if you cut fertilizers and flush. Thus a normal plant should have yellowing fan leaves starting near the bottom. Nitrogen is being pulled from lower leaves.
Light burn issues are going to be on the top layer, and leaves partially in shadow should have parts that look bad and (shaded) parts that look much better.
Flowers want bright light! But as always, the question becomes 'what are the limits'? As the plants stretch, they are also getting closer to the light. To maintain the right brightness you either raise the light or dim it or both.
That said, a plant that is properly watered and fed can stand brighter light than it could if underwatered with improper nutes. So if you are running at the edge with nutes and lighting, parts of the plants are going to go over the edge and start showing problems in some parts, not in others.
And "I turned my light to 80%" means nothing. How bright is it? That's your job to figure out, not ours. You need a proper meter, and they are not cheap. If you are going from a chart, then look at it and tell us the estimated PAR.
