one old leaf at the bottom? If isolated, i'd ignore it.. a plant does shed a leaf on occasion.

It looks like one of the older leaves which happens, but also looks like it’s had some liquid spilled on it at some point as well. Not much to worry about at the moment. The others seem fine

Lock out or lack of nutrients ?
I am having trouble identifying if this is a lockout or lack of nutrients. I was told to stop flora micro. I have been giving 50% strength of what the bottle suggests. My other plant same tent just had a lockout and I flushed.

Nute burn or something else?
My middle and top leaves are yellowing from the tip and edge inward, is this the nutrient burn or another issue altogether? Runoff PH was 5.9 and ppm was 700.

Brown/Grey spots on the leaves
Hey, I hope this is my last question for this grow :P I've noticed some brown/grey spots on the yellowing leaves, what could they be, deficiencies or sunburn? I'm still feeding the plant with nutes, but the next watering will be a flush, so I didn't expect discoloring before that

I think it's calmag and lack of nitrogen but any ideas. I've been busy in the garden so have taken my eye off the ball. She looks in great health with praying full leaves but her colour is off. Any ideas would be taken with gratitude.

Leaves are turning yellow and dieing. Looks just like nitrogen deficiency. I'm in early flower
Losing a bunch of yellow leaves during early flower. I have WPM but it wouldn't progress like this would it? I think I may have just been underfeeding or my pH is off. What do you guys think?

Burn leaves? Yellow leaves? BIg problem? (AUTOFLOWERS)
I had a problem with a lack of magnesium in the larger plant and I applied a little with a sprayer directly on the leaves, I got confused, I sneezed once on the leaves of the smaller seedling. Can I do something to resolve it? I even thought the LED was too close and I raised it
