My plant seems to being going to shit. Can anyone tell me what's going on? I'm on about week 4 of flowering with little pre-flowers showing but all the pistils coming out have very little to no trichomes. I'm using natural light to flower. Plant is in a 3 gallon pot using plain soil. Haven't put any flowering fertilizer in yet because this problem has been getting worst for the past month. I did add worm castings a while back, but not too sure if that's the issue. There is almost no bud growth. I checked the PH today and it's around 6.8-7. I have a feeling it could be a build up of salts in the pot or a high dosage of Nitrogen. I just flushed the plant and it seems to look much better. You can see the details from the photos. Change within 5 minutes. Not too sure what to do next. Any help?
