I am wondering how many growers follow the fertilizer charts? Specifically, the chart will typically recommend giving a certain amount of grow fertilizer thru the veg stage, then switch to a certain amount of bloom fertilizer for the flower phase of growth. See this chart for flora nova for reference: https://generalhydroponics.com/wp-content/uploads/assets/FloraNova-Professional-1-Part-Nutrient-System-Feed.pdf
My issue is whenever I follow the chart, and switch from grow to bloom, I have deficiencies usually around week 5 of flower. However, my current crop I mixed grow and bloom, starting at 75% grow and just 25% bloom feed for the first 2 weeks of flower, then 50/50 until the end of week 4, then 25/75 until the end of week 6, and finally now 100% bloom feed for the last few weeks.
The results have been amazing, no deficiencies at all, green and healthy right thru middle of week 7 now. They are so top heavy I had to order a 2nd net to hold them up. They are super sticky, smell great and look really healthy. Once I switched to 100% bloom feed, I started to notice a little discoloration in the fan leaves, just like I would typically see in week 4 or 5. Those deficiencies, however, did not look like a nitrogen deficiency but more like p or k deficiencies. I am convinced the lack of nitrogen was the cause, and that the bloom feed does not provide nearly enough nitrogen, but why not?
My question is why do the manufacturers not recommend a blend, and instead the chart shows switching from one to the other? Does anyone else blend the two? I've never seen this issue discussed before, but if it has been well covered already, please post a thread link.
Thank you!
