That's my point they look fine because they aren't experiencing any negative effect. You are either simply wasting nutrients or they are using them. My point was there are many explanations besides the obvious and your plants look good. This 'hobby' is very simple and very complexOk i think i get what your saying, something to def watch out for in the future.
as of now, i doubt its possible mine are overfed, they have only taken nutes(floranova bloom) 3 times in their life, 2ml/g 3ml/g and then 5ml/g with a bunch of ph water feedings in between.
Like i said, more of a variation/abomination of the lucas formula lol
the first 2ml feed was given to them back on Dec 20th/ day30 veg, immediately after the plants started showing slight N tox, i assume the FFOF still had lots of good stuff left in it at that point. They never took another nute feed until Jan 5th Day 46 veg which was 3ml/g...I flipped them on Jan 6th.
Yesterday Jan 14th they took 5ml/g Day 7 flower
As of now i think they look fine, obviously im new, so there could be something you more expierenced growers may see, that i do not.

In other words the explanation (we think of) for what we see may not be what actually happened.
