Furcifer.. can those forms of n cause buildup in the soil since the plants cannot use them? Would it be causing my bottom leaves to yellow and die off?? Happened last grow too and i still cant figure out the issue.. flushed my ladies but it seemed to make it worse. Not really worried cause the buds are still growing and frosting up nicely just wonder why they arent staying healthy through out flower. Hoping flowering with the organic soil im using will make that quit happening.. damn chemicals!
Well in theory and crop lands made incapable of continued healthy growth. Without excessive soil amending.
The overuse of Chelation is more the culprit.
Think about it.....chelation holds a mineral (heavy metal) in suspension. Traveling with a host mineral. The chelated binding and/or host is eventually released for metabolism. The chelated binding that has been synthesize returns to the grow media. To attach to any other mineral available.
Cycle continues. As long as these minerals are bound. They can not be metabolized.
Concept and this type of use is highly unacceptable in the agricultural field.
Chelation in agriculture is used sparingly to deliver needed nutrients at the right time and amount.
Not so in the CANNABIS NUTRIENT field of profit over health concerns in an unregulated product.
Thus FLUSHING REQUIRED!
I don't flush per say with natural/organic ferts.
The systematic reduction of nutes at the end of flower.
Will send remaining reserves of nutrients to flower finalization. (This is the plants goal, reproduction before death).
24 to 48 hours I will run clean pH'ed water.
This is to promote osmosis of chlorophyll during the drying period.
There is a lot more to This!
Just trying to put info in a nutshell.
Pinched this off dos this am. Top of plant....cal mag def???
Picture?
