Hi ,

I'm new here and was hoping you clever growers could give me some advice on my first coco grow.

I previously grew NFT until the dreaded pythium monster hit and so decided, out of necessity, to switch to coco.

I have 5 white widow feminized seeds - all sprouted uniformly and seemed ok. But now, 15 days on from germination, they are to my mind extremely small -about 3 inches high and on their 3rd set of leaves. But they look 'bonsai' if you know what I mean, and there is no visible growth.

Thing is, this is exactly how the seedlings grew in NFT when they were affected by pythium/root rot.

I've sterilized the grow room twice with bleach solution, pots and all watering/measuring tools are new and have been sterilized and are washed and sterilized after each use. The room is clean and spacious and empty apart from the plants, lots of mylar for reflection etc.

The set up is:

Canna Coco and nutes - I'm following the canna nute schedule ( Canna start, Rhizo, Trichoderma)
Using bottled water
Plants are in 9" wide pots
440w lamp
Grow room , not tent, plenty of air movement etc.
Temps steady in the low 20's

To be honest , I can't work out how often to feed with coco - do you let it dry out or feed daily. So far I've watered with the recommend nute mix three times since germination. Two of the smaller plants have roots coming out of the holes at the bottom of the pots which suggests growth, but why no leaf growth?

I just can't believe that pythium is so bad in our growing envirnoment that it would hit us again , but this slow growth is indicative of it , isn't it?
I've literally done everything to prevent it !!!!
Please help!!!!!!

I have pics but the files are too big apparently. If anyone couyld tell me how to compress/upload them, it would be great

Thanks
