I wont disagree with you as your way works for you and my way works for me thats the beauty of all this , lots of methods work , but what you are saying is what this guy has already done and his plant is not good , best he try something else , if the plant is not turgid it is not going as good as it can go simple as that no matter what system or method you use its very important to get and keep the plants metabolism into go mode , you can use the best food on the market but if the plant isnt firing it isnt metabolising the nutes properly and probably creating nutrient block which inturn showing signs of stress and deficiencies which is not the nutrients fault .
Its like a young person can eat junk food all day long and show no signs of problems or weight gain because a young persons metabolic rate is fast and he just burns it up , give the same volume of junk food to a 60yr old and he will gain weight like crazy and prolly have a heart attack , his metobolic rate just carnt handle all the calories and energy density and if you keep feeding like this the body will create a state of nutrient block to protect itself from overdose of nutrients , its well known in medicine that you can create a vitamin deficiency by giving to much of that vitamin .
For every action there is a reaction , balance is the key and the whole hydroponic industry operates not with balance in mind , but the opposite , excess, it must create excess so people keep buying new super additives with amazing claims which most are really snake oils and do nothing for you
Purple on stems or veining , will come if the plants are cold , shocked or stressed and as you say nutrient deficiencies , people seem always to say its deficiencies first , I think the other two reasons are generally more the culprit most of the time when it happens .
Slight purple hue on the leaf stems is normal .
A friend of mine just introduced his clones into a greenhouse system and at the moment the night the temps are around 6 to 8 celius , those clones sat down and went purple basicly overnight , I told him to put a small heater in with them and run it 30min on 30min of from 7pm to 7am , they just took of and now have a purple band for the first 3 inches of the stem , and perfect color from that upwards , he also said he had a deficiency problem .
Its great to show this fella what is working I can also show pics of some beautiful plants grown by a totally different method than yours , but he needs to fix whatever is wrong with his system or method , if he just carries on doing what he is doing it wont fix itself .
Like I said I have not grown using bubblers , but wouldnt evaporation be lost through the pot -cage it self like the way a smoke stack works with the pot drawing like a tunnel because of the hotter temps outside the bubbler ?
I understand it would loose less moisture than a non closed system , but it sounded strange that a small sick plant in 22 degrees temps with a single 600watt light a mtre away would use much water at all .
