So a while ago, due in the large part from being a real slack lazy stoner, i decided just to run my Biobizz bloom ferts instead of the customary grow and bloom from 12/12 all the way through flower. I considered this the easy way and instead of having to measure out two bottles i just did the one.
So about three weeks from 12/12 i started noticing what i thought was iron deficiency and phosphorous deficiency mainly plus a lot of taco shaped leaves with sparse purpling of upper stems and petioles!
I tried a few things but quickly came to the conclusion that i should have added the grow all along and that (lazy=stupid ideas)+weed! So i can only conclude that i was seeing a Phosphorous overdose and subsequent lock out of both that and iron plus i read maybe manganese and zinc. I even thought a pH problem at first but thats stupid because i dont get them.
With every screw up i like to take somthing away i.e. even though i did somthing stupid i dont appear stupid! Here i learned that straight switching from grow to bloom at 12/12 is bad, i needed to wait a couple of weeks till first flowers form and then ease it into my grow and sooner or later lower the amount of grow as the bloom increases.
Going from one NPK value to another is bad for plants and the bigger the gap the worse the impact or so it would seem. A transitional period is needed and during preflower my plant is still pretty much Nitrogen heavy. Only when i actually get to flowering start should i really consider my bloom.
My Biobizz chart dose state this although i never found the values on the chart to fit in with my grow finding it easier to judge what the plant wants but now i have a solid experience of how plants are not really wanting such a high P/K fert with low Nitrogen at the start of flowering. Most info seems to point to week 4/5 being the moment that my bloom ferts exceed my grow ferts and grow ferts decrease slightly.
One grower has timelessley pointed out the need for Nitrogen during flowering but i would like to take this futher and say that Nitrogen should be balanced against the Phosphorous and Potassium with the P/K only exceeding the N at week 4/5 of flowering.
So to conclude i gave my plants a decent dose of my grow ferts, Biobizz fish mix, and they seem to be making a remarkable recovery. I always took Phosphorous for granted before but too much in your soil is a really bad thing, it didn't take long to start locking out nutrients and the worst part is it seemed to lock itself out in excessive amounts making me think i had a Phosphorous deficiency and adding even more of the bloom ferts and even higher P/K.
Time of recovery was about a week for most afflicted and phosphorous abused plants but bud size suffered quite a lot especially with just flowering plants. I hope others find some meaning in this and thanks to the grower who kept on saying Nitrogen is all important for flowering, surely it dose need balancing correctly against the P/K and it is the last thing i would have thought about without his efforts, especially in flowering.
Peace
