Hi gang

DTW.
65%humidity.
27 celsius.
Constant airflow and movement.
Coco with 30% perlite.
3L fabric pots.
Plagron coco a+b, power roots and pure zym at 75% strength of week 1 schedule.
LED with 440 meanwell and samsung chips, 3 of 5 lightbars on. 1.7 meter distance.

Put them in 3L pots monday, gave 1L og 50% strengt, no runoff.
Gave another liter yesterday at 75%.

Looks like shit to me. I love this hobby but im getting tired of failing. This is my 5th attempt in 7 months. Never gotten into flower.

Can anybody see from the pictures whats wrong? To much water? To much nutes causing lockout?

Thanks in advance for any reply

Looks like they’re just getting over not having roots for a couple weeks. Give em a week and I bet they’ll recover.

I'd try to add some cal-mag (add and mix in well before nutes) for a week or so...may just be the usual coco & LED combo that comes up a lot...which seems to simply just need more cal-mag. (Usually 5ml per gallon)
Didn't see any listed in the first post about it so figured I'd suggest it. :P

Thanks for your reply Maker never heard if the led coco calmag issue. Have to google it now. Just switched from biobizz to plagron...

But does it look like a calmag issue to you?

I'm really bad at nute probs, but it does look similar to posts about yellow leaves and droopy.
Sometimes its just a bit more nutes and others I've read were just a cal-mag bump.
Best I can offer is a chart you can decide for yourself...

I had problems like this when I first started using coco-you're probably treating it like soil. How often are you watering? Daily? Or are you watering like soil and letting it dry out for several days? Here are two threads that will help you out: https://www.icmag.com/ic/showthread.php?t=307683, this thread tells you why you need to treat coco more like hydro than soil, and this one tells you how: https://www.thcfarmer.com/threads/how-to-water-coco-for-best-results.122334/.

The hard part for new coco growers is finding the right balance between keeping it moist and encouraging new root growth. You might be having some calcium issues, but I think the primary issue is your plants are getting nute burn as the coco dries out. I would start feeding those around 400 ppm or so, with calmag added, once per day to start, until the roots hit the sides of the pot, then I'd go to twice per day. I think you'll notice an immediate improvement as long as you're using accurate tds and ph meters.

Nute burn can happen in a day, especially when transplanting clones their first time. My guess is there’s a bit of transplant shock as well. We’re not dogging you, we’re trying to help you get to flowering for a change. Something serious is going on if you’ve been at it this long with no success. Light intensity at transplanting is important, most do better with some dimming for a few days. Hope you get it figured out, good luck.

Sorry mate, a bit unpatient by now about 27, I read that you need higher temp with leds because plants transpire less with leds.....
Whats your thougt?
