PH of 6.5 is a bit on the high side for Coco, I would try to get that down to 5.9-6.1.  Also seems to be starting a nitrogen difficiency and possibly underwatered.   You won't ever overwater in Coco as long as you have holes in your pots, or plant is just a sprout.  

I would recommend flushing with water/calmag to wash any nutrient buildup that may be causing lockout away from the little ones roots then giving it a day or 2 to perk up before feeding.   

Hope this helps and good luck!  👍

@shonuff Thanks for the advice. I have it in a 20l fabric pot. How much water/cal mag would you recommend flushing with?

@ausgromie for a smaller plant 1.25ml cal/mag per 1 liter of water should be good.

She is really struggling/starving. Can you give us an idea of what you are feeding (how much of each thing) and what is your input EC of the feed solution. The manufacturers recommended rates are usually far too high. All Shonuff’s comments were 👍 and as Shonuff said, the coco needs to be wet all the time so that 2-3 day interval should be changed to every day in coco, two days at most. In flower mine get 2-3 waterings per day so plants can’t be overwatered easily if the coco is prepared properly. Coco should always look wet. If the coco gets too dry you can get salts buildup in the coco and unhappy plant roots. Some young plants need more humidity too so if you can get that to 60-70% it would be easier on the seedlings and it can recover faster.

@monkeydo Hey Monkey, thanks for the help. Im not sure of my EC as I dont have a reader yet. Im following the schedule from Green Planet 3 part in the image below but at 50% after hearing you guys talk on the podcast.

I have them in 20l fabric pots. How much water would you give them per stage. Eg seedling, vege, early flower, flower. Im a bit lost. I usually water till its heavy and re-water once the pots feel light. Sounds like its not enough.

 

Any suggestions would be great.

That chart does look a little scary.. I’d never feed a 2 week old plant 1.9 EC feed for fear of burning the root zone. If this were my grow, I’d mix a good bit of week one feed at ph 5.8 and flush the pot with this. The feed will give your plant what she needs and the extra liquid will remove anything bad from the coco. Water daily to runoff and keep the coco wet at all times. You are at a disadvantage now with the autos because the bloom clock is already ticking and if you don’t get her growing very soon she will be a runt. Try to get your humidity up too if possible. Young seedling love high humidity and it can lower the plant stress, my seedling like 60-75% if I can manage it.

@monkeydo thanks for the help. Looks like it turned around with your advice. Can't wait to see it finished.

This was about a week ago and even better now. Thanks.

@ausgromie fantastic mang. Cannabis plants are tough little plants and you turned this one around very well. Great job!
