answered grow question 6y ago
Looks like the usual N deficit due to the plant being flowering, however seems to have something else, if i had to guess it would be lack of K. (Don't supplement with N 🤪) Can also be overwatering, temperature.

Lower leaves too pale or yellowing?
I am noticing the lower leaves of my Royal Critical Automatic to be much more pale green than the top of the plant. Is this a nutrient/light/watering/lst stress problem if at all? First Grow. Started balcony, moved to tent D23. SF-1000 light, 100% at ~ 55cm from canopy.

Ongoing brown and yellow patches forming in week 6 of flower
I've also noticed today a couple leaves looked wet, so tried to wipe it off but that did nothing. I took 2 pictures of the same leaf at slightly different angles to see the shine. It's only the skunk effected (closed similar question prematurely in skunks diary)

Yellow and fragile leaves 2 week
Couple leaves yellowing and bit curved up. I suggest there can be the options: 1) magnesium deficiency; 2) nitrogen deficiency; 3) Light burn. For case it is magnesium deficiency I sprayed the leaves with magnesium sulfate (solution - 1g per 1 liter), but it won't help.

Yellow marks in leaf center and weird King Kush?
There seems to be some yellow marks developing in the center, this tends to be on the outer side of the leaf, especially during over/under watering? Could this be calcium/magnesium deficiency being that the water source is from reverse osmosis? Also, any thoughts about the KKush?

IDEAS?! double cookies auto BSF
I had too much N at the beginning of the flowering stage, I did a root flush and everything got worse! Now, almost 1 or 2 weeks from finishing flowering, she looks like this. After the root flush, I continued with fertilizers normally just like the others and the others are in good shape!

Yellow stripes have appeared on the new leaves and brown spots on the old ones. But the plant doesn't look sick overall (age 3 weeks).
