Nute uptake slowed down after stretch? Pic

nvm

im going to answer this, for anyone else wondering,....if there is anyone else that has wondered lol,...no. it was my mistake of not checking the runoff during this whole grow. it was about 800 ppm higher than what i was putting into it, causing a pretty bad phosphorous def. to correct it, i followed others advice online and made a 1/2 strength solution and watered them heavily (lot of runoff untill i saw the right level of ppm and ph) for yesterday evening and this morning. things, i hope, will be back to normal soon and the purpling that ive always ran into during flowering, will go away. this is why i love coco more than soil. imo, you learn so much more about your own mistakes. in potting soil, the mistakes were more or less made and corrected for me (not talking super soil, i would love to get into that someday). so if you are dealing with purpling like i was and have always in the past during flowering,....dont just go straight for the calmag. check your runoff first. .............just sharing what im learning folks
