ok that said,think about this,coco has to stay moist period,let it dry your in for a world of mess,so you think your over watering it because it all moist right,well it supose to be,when the plant is small you look at it needing exchange once a day,in solo cup maybe every other day,but when you break out in full veg and then flower,you have to exchange that air ,and the nutes it needs,by feeding to 20 to 30 % runoff your washing out the left over salts,now if it dries those salts dont wash out so much and so being wet it always has nutrients when it wants it,it is the air and nute exchange that makes the plant flourish and grow like a WEED same thing as in your yard,the more you mow the thicker them bitchs come back hahaah,
but moist is what you wont and at 3 weeks in flower i was exchanging air and nutes 4 times a day,alot of work,you cant slack with coco when it happy it put buds in the jar,make it unhappy and you got a hell of a ride just to harvest,i dont even think you can over water coco,might be able to over nute them ,but that were your ppm count for the stage of growth comes in,more problems are caused by boasters and bullshit,instead use the basic and you be surprised what the out come a be if you dig what im saying,it doesnt hurt a damn thing to feed fresh water once a day and most times recomended to wash some of the salt out,but i wouldnt go 2 feeds without
calmag in one of them,so im thinking your convinced you have a N issue,ok so lay off the n for a feed come back with a half strength of N next feed after that,balance it out ,what is the ratio 1-2-3 as far a NPK goes and depends on stage of growth again drainage has a lot to do with it too so does air movement when your media is always moist air movement means a lot so ya hope you kinda understand what im saying,im by no means a coco geek im just explaining what worked for me in my endeavor,shit im lazy and just stick to soil unless im hurting for medicine and want fast meds if you dig ,coco is freaking work hahahah
