Your plant is sucking P from the leaves, it is normal to become yellow. Take care not to overfeed potassium and it seems to be demanding for it... Your plant looks like the sun, it's beautiful!
Tell me about your grow tent, there's enough air intake? What side it's?
@@m330k, good to know man I just finished my setup, nearly exactly the same but my tent is 140cm high so hopefully I won't run into issues there. Think I'm guna start a diary for my runtz so be sure to check it out 👍
@De573,
Smelled nothing in the room, this filter perfect for this tent size. The T&D fan is more then enough, no need for extra intake fan (and extra noise). I use it with speed controller on very low rpm to keep noise level low.
Not the Light! If look at your plants your lower leaves look the same. I use the ts 1000 and my leaves look ok. 23 cm are really to close but at your picture it looks like the light is more far away. For me it looks like a late Mg,K or Zn deficiencie.
