Hmm I can't treat them differently with the hydro system that I have, they are all connected to the same tank with the same nozzles and nutrients and everything. Also by all methods of checking if they starv or have enough food I'm not sure they are starving. I read somewhere another way to check if there's enough nutrients, is to check the EC daily, and if it drops that means they eat more than they drink water and should be increased, and viceversa. So far rinsing them and stoping the feeding for 2 days has turned them around and they are clearly recovering. If what you say that I'm starving them were so the effect of what I did flush + feeding stop shouldn't have been the oposite and they would get worse?
I'm really unexperienced and I don't know much but on my first grow I did the method you suggest, mainly because I didn't have an EC meter, so I added 1/4 then later 1/2 etc... after about 30 days my plants started to show problems, quickly ordered an EC merter and turned out the solution was at about 2.8 EC. After fixing the solution to a 1.8-1.9 strength and a rinse, it all went back to normal. Why would it be so different now? Incidentaly the plant that was the most ill now, is from the same batch of seeds as my previous grow...
I don't wanna sound like the noob who argues and knows best but I can't find logic in what you say, if the problem was they was starving, then what I did (starving them even more for 2 days) should of made it worse not better don't you think?
On a seond thought the problem might have only been that the lights were too far, and lowering the lights fixed it, wich is another thing I did, and then feeding and nutrients have nothing to do with it.
Anyways, so far they seem to keep recovering, I had another issue this morning, we had a power outage of about 6 hours, but I don't think this is any concern with auto's.. or is it?
