since your tips curled up i would suspect the nutes for this mishapping. do you pH your nutes/water before feeding and measure them as in according with the feeding plan?

If you're watering them all evenly, and heating them all evenly, either its a nutrient problem, or its just the runt of the litter Are you using plant food?

mmmh, question on what volume of water do you use this.

also, this plant is young and your mix sounds full strength already to me, so this my cause the trouble really, in hydro the first weeks long you only feed 1/16 or less to 1/8 after about 4 weeks un-topped grow! too much food not only kills people dude

Thats a pretty cool thread. My plant has just been grown in potting soil, and I use a commercial plant food. Its no giant, but it's doin fine. I have no clue what the ph is whatsoever But I grow a lot of plants in my room, so I like to think I have somewhat green fingers.

Could you take the affected plant away from the others, maybe to grow innatural sunlight for a while and see if it gets any better?
