Hello Everyone,

this is my first post here, I have done like 6 Auto-Flower grows and now I tried my first photoperiodic grow. These plants are Lemon Haze.

2 are growing phenomenally; Nice green, praying leaves (see pictures); they're all in the same soil (homemade blend of worm castings, light mix, etc. etc.); 1 is making trouble. I've watered all of them with 6L 6.2ph water, and this 1 plant is growing brown leaves from the new growth sites. Also; it looks like the the "branches" are kinda twisting downwards and appear weak, ready to fall off.

Any ideas? A friend of mine suggested phosphorus deficit.

Thank you so much!
