Who ever told you to not add bloom until 3 weeks after flipping? Some bloom is used all through veg to give a complete balance of all the nutrients then Bloom is used more heavily plus bloom boosters at the flip to promote more bud sites and rapid development of them.
I personally use my bloom boosters and a full dose of the Bloom base nutes a week before flipping to "prime the pump" so to say and have great results. The stretch period after flipping is when plants feed heavier than any other time of their life and need a full compliment of all nutes to give the best yields. Every nute maker has has heavy dosing of bloom and boosters listed on their nutrient charts so I doubt they're all wrong.
3 weeks is after the stretch for most strains and an important feeding window is missed if you wait until then to feed bloom.
Many here use a vast selection of hydro intended nutrient lines.
Even soil intended lines are supplied with feeding charts that are,,well, rather strong and more like pushing the plant then feeding it!
You can push, it's not that hard. The thing is they follow these and many nutrient lines over do it. High P is really NOT needed much.
Yeah a bit more later in bloom is a good thing but, hammering it at the flip with sometimes stupid numbers of P value, simply causes early yellowing due to P tox. This gets worse as bloom goes on and they end up with lower quality and reduced yields!
I've read your posts. I can tell very easily that you have education and experience. Now I can tell that you have your own style of growing that is again different then mine and others on the site with what I would call "our level of expertise". I have no doubt what you do works for you! I'm not going to stoop to demanding "pics or it didn't happen". I already can tell it does for you.
There is it is too, you do what works for you. Others do what works for them. I do what works for me. I can fairly say that delivering any extra P in veg was never an option in my book for this tropical. When I did spend time (plenty of it) on synthetics (and I still did my organic few, as I love the work involved). I discovered real quick that raising the P early was dooming my quality.
I and others here find that the use of high P "bloom" foods can be and are for the most part, counter productive if delivered in the available concentrations sooner then week 3 of bloom. I like to suggest that novice growers mix the veg and bloom at a 50/50 ratio for that week and go full on bloom at week 4. You know damn well the plant will go around 1-2 weeks longer anyway, so your not loosing anything to get the intended result. Other then that early yellowing and burnt end result we see around here all the time.
I suggest that if you want to promote your style of nutrient use.
You supply it,, with amounts, ratio's, application rates and frequency of use. To simply say xy or z is wrong based on what you do...can be not so correct as you may think!
At least you asked! I answered too!
BTW, I like the part about the minor fungal infection! NICE one.....
very well could be! I might spray a Horsetail grass tea (natures own strong anti-fungal) on the bottom of those leaves to see. And yes, they will not "show" recovery if that works. They will simply continue to supply the plant with working leaves (diminished but, working)....that would be
my choice over removal... - 6-1, 1/2 a 12 to the other, eh?
Thanks for the tip-o-the hat on the being sure it's dry enough to water part!
Want to chat some more on the subject?
Drop me a PM and lets let the threads be threads and not our playground......
See yah round eh?
on....
