Could be a phosphorus or potassium deficiency, its pretty common at this stage. It could also just be genetics. Check out other diaries of the same strain and see if they had the same changes around this time. They're looking great!

Small leaves, purple leaf stem and veins. Newer growth drooping
Second time this is happening. Plant grows beautifully until it starts to flower and then I get purple leaf stem and veins, small leaves and grow slows down. Exactly the same issue I had with my bubba kush. What's the problem ladies and gentlemen ? Temp day 25 humidity 45-50 %.

Nutrient burn, Light burn, or Phos Def? red stems purple bruises,
Noticed red lines leaking red into the leaves with purple bruising, and the starter bottom leaves seem to be turning yellow, with the leaves above looking dark green with spots. Is this signs of light burn or nutrient toxicity? And is it lacking phosphorus or just the strain gen?

Turned purple and bent down.
Is the soil too hot? Had her in water and planted in soil today. Did I mess up? Usually DWC grower. Trying something new.

These plants havn't had the best start. I followed the house and garden feed chart but used roots gold instead of silver. Imonitored ph, temp, EC, humidity often, everything was good.?
