I am on my first grow and at 16 days old my plant is showing yellow leaves starting at the bottom. I am using Coco as the medium and general hydronics Go Box (dosage at 1/4 to 1/3 only) nutrients. I test pH levels before watering and the runoff and was between 5.5-6.5. I am using 184 watts CFL bulbs in spacebucket. I am on a 20/4 light schedule. The bad thing is that my humidity levels are bad here. I am running 3 humidifiers plus wet rag in bucket and 2 USB powered mini humidifiers right in front of intake fan and got humidity up to 56 today. Without a humidifier my the was 20.
please help!!!!!

here some pictures

Here my plant. Is it maybe to much nutes? I did not use full strength started at a 1/4 amount (0.25ml per liter, then 0.5ml then 0.75ml)

Your pot looks a bit small, could it be root bound? Doesn't take them long to fill a pot, @ 16 days I'd figure you'd be in at least a 1 gal pot.
Plant still looks vigorous.
 
Dear greenstate,
Thank you so much for your reply! I was scared to transplant when leaves turned yellow but will check for rootbound issues. I have a pot I made from landscaping fabric. I will definitely check that!
Thank you so much!!
 
Update!!!!!

My baby has Brown discoloration now !!!! State of panic setting in !!!!
Will check out your advice!!

Transplant and feed with just do water and cal mag, try moving closer to light as well. Remember, this is a weed and doesn't require to much attention. Sometimes we over think these things. The water and cal mag should be every other feed.
 
Hi,
I am totally lost still.....maybe I need to wait longer but it looks like things are getting worse.
I transplanted to a bigger pot 2 days ago and added calmag to the water. PH runoff was 6.3.
Maybe I expect to much to change in a few days.
Will still keep you updated.

I water when the top of the coco is getting dry or lighter in color. Usually daily. Sometimes I have to wait another 12 hours to water if still wet.
I started upping the nutrients to 1/2 strength but still not much change. I also got hydroguard yesterday and I will try that. I fed calmag at full strength and I water until I have runoff.

i am confused however...some people say water everyday nomatter what and how dry/wet the coco is. Some say wait till it needs water. I grow a lot of houseplants and herbs and gardening and seldom had problems. As this is a "weed" technically I am flabbergasted.

I will post another pic today. She is still turning Brown on edges and yellowing. Maybe the coco was a bad batch but I am using "nature's agro products" coco.

I think maybe as a newbie you read so much about it to get it right that you actually mess it up. Experience is what I need. But that will make me mess up some.

should I maybe flush her?
any help will be appreciated!

Thank you,
​​​​​​​confused newbie
 
I would flush with 6.3 PH water and let the pit dry till it's light as a feather, probably about 2 to 3 days. I'll check back in a couple days and explain a little more about watering coco.
 
Thank you so much for all your help.Mr.furley, I would love more advice!!! What my confused newbie mind made me do is to flush her and then start to up the nutrients for 2 days and then in frustration I topped her also. But even under all that stress I was shocked to see her looking better. However, I still think ( judging from online photos) that her growth was stunted before. I do not know because height seems to differ from Type.
I think maybe my lights are too high up. I am limited to a bucket with cfl's...but I think she looks better. She is 4 weeks plus 2 days old. And I have been watering daily until I got runoff like about 20%
 
No problem, so with the watering.....
You can water everyday as long as you get runoff everytime, but I think it's a waste of nutes, water, time.... I personally prefer to water to runoff and let the pot dry till it's lite when lifted or dry two knuckles deep, sometimes that's a day and some times its three days.

Make sure you give your plant time to recover, and change things slowly as to not shock your plant.
Cfl bulbs can be within 2 inchs of the plant, just watch closely as the plant can grow in to them fast.
I would start to up your nutes a little each feeding, your plant is old enough for it, if you start seeing tip burn Back off a little.

I personally don't feed every watering, I alternate
Plain Ph'ed(6.0 to 6.3) water, let the pots dry then feed, let the pots dry and repeat.
If you have anymore questions don't be afraid to ask and if you can share picks of your set up and plant it really help with a quick diagnosis.
Good luck and happy grows
