Okay week 5... play it real differently then!
First off, the plants might benefit quite a bit from a larger home. The new soil should be light with GREAT drainage to prevent overwatering and maximize oxygen to the roots at this very important time in bud development.
Next, late in flowering, yellowing low leaves is not uncommon or even undesirable. You have ~3 weeks to go if you are running an average indoor strain, and that is about what I'd expect to see.
So my advice:
Larger pot with good drainage, fresh light soil, and as for fertilizing, keep doing what you're doing. Let the soil dry out a bit between waterings too.
stinkyattic Reviewed by stinkyattic on . White Rhino YELLOWING LEAVES Naturally I am a little worried, so I decided to post this, in hopes of some feedback. Have 4 White Rhino ladies.....soil grow w/ 400w HPS in my walk-in closet. Started flowering.....and the first oddity I noticed is it tool a good 2 weeks for pestils to show on a 12/12 cycle (from 20/4) which is longer than any strain I have ever grown. Used FoxFarm Open Sesame (1 tsp to a gallon every other watering) and water every other day, 1 1/2 gallons for 4 plants. Everythiong seemed great. Last week Rating: 5
