This is my seedling is this bormal size for a weekold i see peoples plants 3 timea the size of mine at 5 days lol
Yep, well it may be a little small, you should be ph'ing at 5.8 to 6. but you should look at the humidity and temp as well. A nice high humidity around 75 and a temp of 83 is nice growing conditions for seedling.
I would try watering with nutes at 25% strength and ph'd to 5.8. People swear that you can go two weeks with no food even in an inert medium like coco but past experience leads me to disagree.
