Deficiencies with high PPMs

[Baloni]

This is my second round with R/O water and I guess it does more harm than good but I will learn

R/O is superior for growing and I use it in a bad way.



I look at my round year ago when I dont have R/O yet.

In bloom I was at 600ppm nutes 200ppm tap water... and I can see now they were slighthy burned from nutes.


I have nutelock due to high concentration and It looks like deficiencies.


Dont get be confused with rapidly dropping PPMs when they are eating... it doesent necessary means they need higher EC like this chart said. They just need stable and lowest concentration possible.

some plants can't handle "normal" nutes (100% mix).

Some plants can handle Double or Triple nutes - and do great.

The "lite nute" plants are often VERY worthwhile, e.g. some real smoke-able varieties of Apollo 11.
