Is it nutrients? Light?

Hi guys! Thank you all for all your answer. I am pretty sure it all started with the light. It is a shitty light the one I had. Now I have a really good one. After the light burnt, she fell into stress and now she is having a potassium deficiency. I am trying to fix it by adding more potassium. Thank you all guys!

Hi .normally red ,purple on the stems nd leaves are caused by stress . The way the leaves are hanging looks like heat stress . Flush her wth some nice clean water nd I'm sure she will b fine also monitor your heat inside the grow space .

Thirsty and hungry plants in general. Red stems are usually genetically related and perfectly fine, but can also be a sign of phosphorous deficiency, which in this case, is probably the most likely reason. Either way, they certainly need more NPK and more water too. It is not light related and I would be putting the other light back in, lumrns = health. In reality, red stems are not an issue worth worrying about, it is more fear mongering.

Hey Growmie, The overall pale color alongside the red stems means this plant needs higher levels of nutrients overall. Hopefully this was helpful and remember ... "Happy Growing" and "Free your mind one puff at a time"
