I doubt youre gonna flush out organic nutes. Especially if its hot.
I also think switching over to what is called Bloom Nutrients is a mistake, and in most cases a marketing gimmick.
According to Tissue Analysis weed likes a 1-1-2 nutrient ratio all the way through its growth cycle. The only exception is they can benefit from Mono Potassium Phosphate in weeks 2.5- 5 in an 8 weeks flowering strain.
Many of these so called flowering nutrients cut way back on Nitrogen. Which is a mistake.
All Nitrogen is, is Protien. Humans eat Protien, and our bodies turn it into Nitrogen. Plants skip the eating of Protein process, and just require Nitrogen.
During flowering plants will grow the most they have so far in their lives. It makes no logical sense to cut back on Protein, when youre trying to grow.
Like I said, plants just need a steady diet of 1-1-2 ratio, and each week should get slightly more food, up until the 6th week flowering, in an 8 weeks strain.
While I mostly use chemicals, the ratio I use is 19.5-20-39 as my basic feed. I feed small amounts every feeding.
I use Calcium Nitrate 15.5-0-0
4-20-39, and Epsom Salts, which equals 19.5-20-39. Weed likes 2x the amount of Potassium, as it does both Nitrogen, and Phosophorus.
I just increase the PPM each week as needed, but only slightly. This also applies to Epsom Salts. Epsom also contains Sulfur, and is responsible for Terpene production. Is also the #1 most common deficiency in container grown plants. Weed is a high magnesium user.
For organic I use Peruvian Seabird Guano, both Veg, and Flowering formulas, Potassium Sulfate, Kelp, Azomite, Calcitic Lime, Dolomitic Lime, at a ratio of 2/3 Calcitic, to 1/3 Dolomitic. I use Promix BX as my medium.
