The plants are extremely happy and healthy. #4 has grew so much the last week that it now my favourite plant yet and there is still no buds. I've done an experiment of my own to see for myself, #1 has been fim'd and #2 has been topped. There seems to be no signs of stress and are still growing steady.
Yeah the pebbles help with watering, they keep the coco and roots together and the roots come to the surface under the pebbles and fill the pot more. Thanks guys
The purple stripes are due to Mag deficiency.
Magnesium deficiency is mostly due to overwatering or too much light (light is too close or too powerful). Adding CalMag Agent won't solve your problem until you fixed your roots or your lights.
@JUNGLE_B4RNS, I'll move her away from the light I'm running the bulb at 400w ATM. The others are perfect so I'm not planning on changing anything right now. Thanks man
@BreakingBud,they came from seedsman around 2 years ago, I'm sure they are dinafem's cheese automatic. It has been some time since they were purchased along side 4 other cheese strains so I could have them mixed up.
