My first DWC auto grow. It is about 20 days old I would say atm from starting to germinate the seed.
Fairly sure I damaged the tap root moving the seedling about a week or so ago. upto then is seemed fine with one set of true leaves and dark green colour.
A couple of days ago it had stalled for several days but picked up adding extra leaves but colour has lightened and some brown spots on some of the leaves.
Yesterday I noticed the roots were not in the solution under the net pot but raised the solution level so they now are in the water.
Previously I have been wetting the root riot sponge using a water pump (you can see the green garden hose this comes out of in one of the pics)
ph is 5.4 atm but was registering as 6 yesterday. Has been in this range for several days since i got a sensor.
EC/PPM is 1.25.
I have lightly chlorinated tap water that is slightly hard and have added General Hydroponics 3 part Flora Neuts at 2.5ml per 10l and some Diamond Nectar Fulvic Acid plus General Hydroponics root stimulator at recommended dose.
My tank is 100 liters- so it is big for a seedling. Temp is 17 degrees celsius
Has a decent air pump and a couple of stones in it on all the time.
Room temps are 18 to 25 celsius and humidity around 65 to 70.
Have also pumped ozone via the air stones using a DIY ozone generator for a few hours a day
I have had it under a single Citizen COB - added a second yesterday as I am rejigging my tent.
Doesn't appear to be any change in the seedling since yesterday when its roots first went into to solution tank.
Seedling is about 2 inches tall.
Appreciate i may need to leave it a day or so to see if having the roots in the solution turns it around.
Any suggestions , diagnosis advice appreciated.
Thanks in advance
