sealeater as mentioned next to the photo i am a bit concerned with the color of the leaves and hope someone can give a possible explanation keep in mind though i am a very basic grower only having 1 successful grow under my belt and have very limited equipment only a 1mx1mx2m tent and a marshydro ts600 grow light with around 100wats of power as i am still rather young and in college i do not have the money to invest in any extra gear at the moment as i am sure some of you might recomend a stronger light and an air filter but it is at this point completely out of the question. For the growing medium i am using a 50/50 blend of coco and some genric vegetable potting soil untill i transplant it into a blend closer to 80 soil 20 coco. my thinking is that the coco being less dense it will allow the roots to push through the medium easier at the beginning and help them grow faster and more vigorus. The only successful grow was an autoflower and i had it in 100% soil and as tey are known for not having strong roots you can imagine the final size and yield of the plant was laughable.

sealeater hopes high moving into week 4 the color of the leaves is still concerning but as the plant is still growing well im not as worried as before she made 2 new nodes in week 3 and is visably starting on node number 4 any recomendations are always welcome

sealeater hopes higher than ever going into week 5 started lst and just before week 5 i transplanted into 25 liter pot with 70/30 soil/coco mix. cant wait for the new growth to kick in in the following days and weeks
