I’ve been growing 5 different strains outdoors, in full sun for most of the day. I noticed that 45,000 to 70,000 lux is optimal for flowering. Above 70,000 lux is likely to light burn some indicas. I just measured full sun and I see it is 117,000 lux. I wonder if a couple of my strains have crispy and crusty leaves because they got light burned? The other 3 strains have exactly the same pots, soil, watering, location, etc. and they have normal functional green leaves. The two that did not do well were Aurora Indica and Critical Kush. The healthy ones were Cotton Candy, Cookies Kush, and Blue Cheese: Much more sativa-like forms.
Should I get some mild shade cloth to keep the light down to 70,000 lux?
