They need more light, I sometimes grow in coco but in 6 l pots that I let dry out, they love it, otherwise it’s dwc for me or modified Wilma in perlite and flood fed. Coco is able to hold too much water, whatever you read to the contrary, so the plants metabolic rate suffers from lower O2.

It will take more than a day to show improvement.

Today, seems to have some new growth but im just keeping them to see if they were sick. If they recover its my fault.

Got 3 WW and 1 OG kush doing great so they will replace these when dead.

I was going to say those are about trash now. glad you got new ones started.

yeah I figured they would die anyway. Just wondering what I did wrong so I can learn. They got some new growth so im doing something right haha

Wtf is going on here? The new plants did great for 21 days, now this again. Exactly the same symptoms and went from perfect to this is just 2 days.
Giving them 1 watering a day 20-30% run off with 600 PPM canna A+B, roots and calmag. Run off PH is good (+/- 6.0). PPM is around 600.

Its going to the upper leaves in quick rate??? im dying here and so are my plants.

It appears you have plenty of perlite in your mix so I would feed 1/2 strength nutes every day to run off, pH'd at 6.0. Good luck.

It looks overfed

Light green top, bottom yellowing and going crisp. I dont see how it can be overfed. It should be dark and burnt on the tips.

Why would you think its overfed?

Burnt crispy leaves and the fact that you feed 600 ppm's once a day of course you're going to get it sick that's toxicity. You going to take a multivitamin every time you drink water if you do you're going to get yourself sick not to mention whatever it don't take up builds up. that's why it stays dormant for so long until it builds up and then bam only way to know is check your PPM runoff and see what that's at

Do you grow in coco? I feed every day from the day it sprouts and twice a day in flower. If you feed to run off each time there will be no build up. I would show you the results but an error occurs when I try too upload a pic.

whats the ph of your nute solution going in?

No I do not grow in Cocoa but it does not take a rocket scientist to figure out you shouldn't be feeding so high to a plant so small but hey whatever I'll leave it to the experts you tell him what to do

Oh yes and salt can build up in Cocoa.

Even a rocket scientist knows how to spell coco. At three weeks old I feed full strength and never have nute burn or build up, and I have never checked my run off for ppm's - I don't even own a meter. Although I don't feed full strength until 3 weeks, if you know anything about the Lucas formula, KISS, or Hempy's, full strength is recommended from start to finish. I don't give advice to people when I don't positively know the answer from hands on experience. You don't grow in coco brother.

Feeding at less than 500 ppm I never experience salt build up in my coir, and as I said earlier I don't feed to run-off every time. I've just had the pleasure of working with coir for over 10 years now and learning the little nuances of growing in it.
