Howdy,
My first post to this forum and I am desperate to receive some advice from fellow growers.
I am a noob, although I grew two plants in the past and with success. (I use them for medicinal purposes)
I've got two plants on the go: One Pink Kush (very high CBD and no THC) and a Northern Light )Very high THC and no CBD).
Both plants were germinated at the same time and are now about 3 weeks old. The Pink Kush is doing great but the Northern Light is about to die!
The NL started to develop a yellow core about a week ago. It is still growing but looks weak and now starts to develop some rust spots as well (Near the tip of the leaf).
Both are planted in the same potting soil (Perlite, coco coir, and topnotch compost, 1/3 of each) and I have been watering them every second day.
I started adding nutrition to the water three days ago in the hope that this would be beneficial for the NL.
My nutrition is 0.5 ml GROW, 0.5 ml MICRO, 0.5 ml BLOOM and 0.75 ml CALMAG per litre of water with a pH of 6.00
I water every second day.
I use a Mars T1000 light and the temperature sits between 24 to 27 degrees C during the day and it drops to about 15 to 18 at night.
My lighting schedule is 18-6.
I have attached a couple of pictures as this will be much better than a lengthy article.
Your feedback will be very welcome.
Many thanks in advance and have a nice day.
Luke
