Leaf Discoloration - Hopefully Nothing
I'm looking to rest my concerns that these removed fan leaves from lower/center canopy are not simply just appearing so due to lack of light and prior plant tie damage. Focus on the yellow/brown discoloration, actual physical damage is accounted for. More details in main post.

Overwatered cubes in hydro? Too close to the sun? or effect of having add
Hi All, I have issues with my first hydro grow - i effed up. I think i was too slow in the transfer over in the tank. Light is 200 PPFD, EC at 0.6, and barely added any nutes. Did i manage to overwater some of these plants by having them too close to the net pot?

Change in 1 leaf Color
Just watered my plants and I’ve just seen some discolouration in one of my fan leaves at the bottom. The plant seems healthy and all the others look fine. Any ideas? Ph is ok I think and only just started fox farm nutes @ 1/4 strength.

Dying leaves
I had some mild nute burn last week on a few plants. A few tips were burnt. Some lower leaves are turning yellow and dying. Is this still nute burn or something else?

Yellowing leaves
Hey fam, Just ended 3 weeks of flower for this Banana Purple Punch Auto. A heap of yellow leaves basically appeared over night. I fed on the 13th with flower fert (has some N in it) and again on the 18th. This is the only plant that’s going yellow. What do you think?

Underfeeding?
Beginner grower here. Had some issues with underwatering and it's slowly recovering. Now am unsure if yellowing leaves are signs of underfeeding as it's still early in flower or due to the underwatering. Bottom leaves yellowing and dying off too. Using GHF Bio line as recommended
