Using Super Soil and the methods I have shown here, by day 28 in bud, your plants have been in the large containers for almost two full months and you should notice the soil is much lighter than when it was first filled at transplant.
The plant has now converted much of the organic material into a 5-6 foot bush, and if we don’t take action now on a garden this large, we could experience early fade and loss of yield.
We could simply feed the plants a quality organic bloom food (and we still may need to) as these huge plants enter the 5th week and beyond. However, many of our strains will finish perfectly with just a few extra inches of Super Soil layered in on top just before a watering.
Top dressing requires knowing your plants though; you cannot wait until you see deficiencies. You have to know your garden well enough to apply the top dressing before any signs of yellowing appear. I use Super Soil to top dress. It is slightly hot for new plants, but as a top dressing it works wonders. You can see the leaves reach for the sky after a top dressing and watering. At week four, I remove one row and clean out any dead leaves or straggling shoots. Then, I use a small bucket and measuring cup to place about 2”-4” of Super Soil on top of the existing soil. I like to do this when the plants need watering so that I can wet the added soil down really well.

Each time you water now, some of the nutrients will leach into the soil and provide the needed energy and food. I have never seen any burning and for me it takes most of the guess work out of how much and when I would need to feed. It’s almost like a natural time release fertilizer.
There is also no need to flush using this method since over the next 4-6 weeks according to finish times you again use only water each time. With the exception of Bud Candy and some added Sucanat at day 40 and 50, this repeated watering and the plants themselves will use up any nutrients and finish with a perfect fade.
