Is your medium in fact coco?
What pH are you running?
What are you feeding and how often?
Do your pots have adequate drainage?
What are you doing for Ca and Mg?
Mediums pH is heavily out of whack. I guess somewhere around 4.0...
I know I’m new to the forums but I’m not new to growing. I see bad advice on here constantly and couldn’t take it anymore. You can’t overwater coco. It’s in the nature of it that it holds oxygen even at full saturation. Did you buffer your coco w cal mag prior to running these? If not you’re going to need to feed around 200ppm coco with your next feeding and give them some food. Coco has no nutritional value you have to feed every time. Coco has a very low CEC and the nutrients will flush if you use pure water or even low nutes. Bump up to at least 800-900 ppm and water them til the nutes run out the bottom. They are underfed. And if you didn’t buffer w cal mag, the coco is negatively charged and the cation exchange sites pull both potassium and calcium out of your soil solution. You’re basically feeding your substrate not your plant. Feed them don’t worry about drying it out. Seriously, go right now and feed them at full or close to full strength. Flood them. It’s what they need. I grow in coco regularly and water every 6 hours during lights on to probably 20-30% runoff. They grow like trees. I got stalks the size of my girls wrists on some. So trust me.

Are you ph-ing your water? Checking the PH after you mix your nutes? Coco requires you to handle these things. It looks like you're running acidic and locked your potassium out. The moss/algae is from the moisture in the basement. Coco is supposed to dry fairly fast. It looks like yours isn't. If you have a dehumidifier, that would probably work wonders down there. I would def try to get rid of the moss whether people say it's ok or not. It def isn't beneficial and most certainly creates another layer of ecosystem that introduces more organisms. Again, maybe not harmful. But I feel it's not worth the risk.
Edit: Also, it could just be a plain Potassium deficiency. But -K is def what she's saying. The moss is def the humidity.
H All, thank for the advice… hectic few days so il try to give an update and answer your questions, I may have a couple more of my own aswell.
Canna coco plus - No Calmag, as this pre buffered
AN ph perfect micro, grow & bloom - full strength, still always check ph(always 6.2)because it’s only ma 2nd grow.
70%rh 19-22deg - can be altered but led to believe that’s ideal at this stage? Been in this environment for 2 days
24 hrs light
Budzilla veg light
as originally stated, they were in my damp basement in a homemade box open to elements awaiting my tent. I have now transplanted to tent and final pot.
when transplanting i noticed the roots were thickly wound around the bottom of the pot. Could this of attributed to my issues? The leafs seem to be getting worse, even the new growth seems to be going same way?
Or will the change of environment and pots help?
or are they doomed?
thanks again for all your help!!!
