I have the light at 75% i will reduce it down to 40% and see if that helps. I have not checked the runnoff yet. I need them to dry out for a few days and I will.
Im going to let them dry out for 3 days vs the 2 i have been. I also reduced light from 75% to 40%.
What are you’re temps like? Seems like it’s taking to long to dry out
I would also recalibrate your tds/ec meter because I feel like were probably overfed at some point or maybe all along and got to the point they just quit drinking.
I would Raise pH to 6.3. 5.6 is way to low for coir IMO. Make more holes in the bottom and at the sides to increase drainage and aeration. Decrease light, they seem light stressed to me. Don't need much at that stage, either raise or dim the light down.
They stick around 79 to 83. Im betting the light was too bright. I had it on 75%. Its on 40% niw, they opened up a bit this am.
Yes, poked 6 holes in bottoms. Maybe ill open them up some.
Its a blue lab ppm meter. They come calibrated righ, also use my vivosun ppm meter to compare. The vivosun reads 10 pom higher than the bluelab.
Ok. Ill bring ph up a bit. When you say buffer....i ran ph distilled water through the soil in the cups as if i was flushing in order to get the coco saturated before i placed germinated seeds in coco.
Even if you think 'they come calibrated right' you should calibrate before using. Lord knows how long it sat on warehouse shelf in whatever conditions.
I've actually never calibrated my EC pens. It's optional and most often not required. pH pens is another story though, they need weekly calibrations.
Pretty much anything that comes through that can be calibrated, I do. Leaving less to chance is a good thing.
Absolutely wrong.
I apoligize, it had calmag in it.
