Maybe someone can tag someone who also grows in Coco and can help out.
Also starting to notice that the really bottom leaves getting more and more light green / yellow.
Is this a nitrogen problem after the transplant or what is causing this ?
For their age the PPMs aren’t terribly low, the PH is high for coco though. Feed everyday and for the next feeding go in at 600 and 5.6, catch a sample after about 1/2 a cup has ran out the bottom and test. I never test the 1st of the run off, I like to catch a sample where I think it came from the middle or lower of the root zone versus the bottom of the pot where the nutrients may have settled
How about filling out this and I’ll take a look at it: tag me into it when it’s filled out…

My problem is only that the plants are drooping leaves and the bottom leaves starting to yellow a bit.
My initial plan was high fertigation with coco/perlite.
On a 18/6 light schedule i wanted to water/feed 3x daily.
What worries me is that i come from soil and i am worried that if i proceed with the watering / feeding like planed and and if the drooping comes already from overwatering that i might drown them and they die.
Or it might be just something else. And the yellow comes from nitrogen deficiency so i might just up the feed a bit ?
Looks to me like some kind of root issue with the plants ‘guarding’ like they are. With coco at this point the medium should be damp throughout but not necessarily watering to runoff. It’s still too early to think about watering/feeding more than once a day and may not be necessary at all. Generally once a day is plenty so long as enough liquid is used.
Being in coco/perlite it will be tough to overwater once plant has grown into the medium. Remember that coco needs to stay moist or it becomes hydrophobic. I think I would increase the amount of liquid you are providing.
Your TDS is a bit low and would like to see it up around 900 ppm with GH nutes. That’s a good place to stay at throughout veg and once in flower can bump up to 1,100 or so.
I don’t really see any cause for concern: media is going to become more acidic over time anyway so you are not in a bad place. FYI EC and PPM are expressing the same thing, no need to post both if you don’t want to. Most folks here are more comfortable with PPM than EC.
