I much prefer Heavily Medicated's trouble shooting chart.
As Waira said, there is offen more than just one issue at hand.
We often tend to refer to def'c as being a nute related proble.
In my last grow I had two issues which needed attention.
Over watering in soil, because of soil compaction, and Calcium.
Flushing partialy fixed the issue, but the ultimate solution was to transplant into new soil and start feeding again.
And , I'm always very carefull to keep my PH around 6.4-6.5
So I can well imagine some of the issues associated with lock out that occur when PH is off.
That opens up a completely new conversation.
I know Machimillion is presently running some tests on a product called MANTIS.
Its suppose to be PH balanced for all growing mediums and complete with nutes.
No flushing required. I think he's running a drain to waste setup. But I'm not sure.
So for coco or regular hydro, the Matis should be promissing.
I'd like to see some issues crop up with this product, where the cause is not the nutes but rather the enviroment.
Cheers,
pfffff,.... I've seem similar things before and all have the same fault, especially for defc.'s/toxicity/nutritional diagnostics... The chart has it's good points, but as always, no pics means symptoms are left to peoples (ignorant) imaginations (no substitute for this IMO), and because so many defc. symptoms can look similar, appear on different levels of the plant (tell tale for diagnostics, and totally unaddressed in that chart) it will not be a reliable tool to reach valid conclusions on all the time,... Also, more often than not, more than one defc/toxicity. is in play (which muddies the diagnostic waters a lot at times), and the root cause does not get addressed well if at all, to say nothing of how to fix it... This chart may help point somebody the right direction, but there's a lot more to do beyond what the chart offers...
