was growing in hydroton / roots in air PVC with good results. since i have been trying coco coir i seem to be getting lots of root issues.not sure if overwater or underwater, over feed or under feed.advice greatly appreciated.
last time i successfully harvested about 4oz from a plant in 10L (~2.5gal) plastic pot of coco coir , was hand watering 2-3 times each day till runoff with EC not more than 0.7 and still had slight salt build up issues..
second time round i haven't been able to water any more than once per day as there seem to be major root zone issues possibly due to over watering. the roots are definitely nothing to be proud of here. If I let the coco coir dry out too much, the rootzone EC raises drastically and i get burned tips. these ones are about 7 weeks in now , guessing i should start to lower the ec to finish them off. probably won't hit the 70 day mark I did last time round.
i doubt it's root bound either. (considering my last grow had way more roots when i was able to water 3 times per day )
my grows are getting worse each time and I don't know why, spent hundreds of hours reading contradicting information regarding coco coir. tried to follow different ideas but plant never responds well. i suffer from severe depression and anxiety and the inability to grow my own meds is the icing on the cake i do not need.
i accept that I should water less to begin with and then more as the roots grow out, however waiting for the coco to dry even slightly seems to kill the roots and runoff shoots to double the initial watering level with lower PH (salt buildup issue...?) these ones have already been growing for about 3-4 weeks and little progress. they seem to stand up as it dries out , but not long after i start to get yellowing from bottom and burned tips on top. The roots seem to be whiter when the medium is wetter,,, but they keep dying off and I don't know why. been watering these once every 2 days when the top cm dries out with 0.4EC . trying to keep the media flushed every water so nothing builds up. always having these massive purple stem and fan leaf stems. temp is 25 C though so doesn't seem like a temperature issue.
see how some new roots are really white? well if i water again they will die. but if i let it dry out they die too. so confused with coco coir .
here's a seedling that popped two weeks ago. everything seems to go bad when it dries out, but when i water it goes equally as bad. I am so lost with ideas now. i water with rainwater and coco nutrient solution each water.
