Hiya mate what EC or PPM are you running? Looks like really bad nutrient burn to me
With the Wilma you only need 4 X 15 minutes water cycles per lights on. Don't run during lights off.
I tried Hornet nutrients when I started. Came with a kit. It's crap.
Get something else.
First things first. What's your tap water EC and what's the tank running at?

Alright treetrunk thanks for the reply
Not too sure on ec av never tested for that before I let the water stand for 24 hours before I add nutes and add to the tank the ppm was 500 I think? Sorry am all new to this system
Would you recommend a nutrient brand for this set up?

hi looks like result of low temps what are your stats ?it appears to look like over feeding but is not its the cold making plants not feed,i know this as my unheated veg cab has exact same problem and my next payday i must add a heater.
but yes stats and feeds etc might help be more conclusive,good luck

I'm getting good results with Mill's and not too many bottles to arse with.
Get yourself a PPM meter and PH meter they are a must have. About a tenner on eBay.
What stage are the plant's at?
