It's a pH flux. Need to drop your pH more when watering. Bit of Calcium won't hurt her either.

Hi there! Check your pH and make sure you don't have any lockouts or anything. That yellowing starting from the tips looks like a Potassium (K) Deficiency but those curling leaves and darker green says you might have something else too.

Root rot?
I feel I made a huge mistake. The last two weeks I suspended the top bloom fertilizer and star to give a considerable amount of organic molasses (at EC=1.4). The soil turn compacted, and leaves begin to yellowing. Is the plant showing signs of root rot? What should I do? Help!!

Is it light burn?
Could this be from light burn or is it something else? Moved my light 15 cm higher for now. Some of the branches are showing purple color. That means stress for the plant right?!

Leaves turning yellow
So my royal jack automatic started getting some yellow leaves on the bottom and they started going up. She is on the 6th week. Should I be worried or is it just normal cannibalizing?

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.
