Like Finn said, overwatering is a big problem. That "funky" smell could be root rot, and your PH is on the low side for a soil mix. Get it back up around 6.5. On top of the overwatering you are now flushing as well to compound the problem. You must let roots get air. No air to roots=saggy stunted growth.

Get reading that thread Finn gave ya. And what are you seeing that is telling you that you are 9 days from the end?
