first grow

[al70]

hi everyone, this is my first grow, these are five feminised critical mass 3 weeks old, the first 2 leaves have turned very pale and there is some curling on the sides of there new ones, they're growing under cfl's using general hydroponics nutrients using a nutrient schedule that I got from a site called grow weed easy dot com, maybe i'm just panicking but i'd really appreciate some help, cheers.

They look ok.don't know the growing medium. For instance if it's soiless (potting mix) you should not feed anything at all because there is enough nutes in the mix for a while. Most mistakes are Overwatering, over feeding, medium to heavy (not enough aeration). You could try a small amount of epson salt in ph'd water 6.0-6.5 very small like 1/4 teaspoon per gallon.

I forgot to say what medium, they're growing in coco canna professional, I've been feeding them nutes since they sprouted from seed, i'm not watering them until the medium is dry to my knuckle, should I flush them so soon????? thank's for reply, cheers

they're looking ok but Ease off the nutes,don't begin feeding them till the first oval leaves turn yellow. Heres a link to the GH feeding schedule for coco = http://www.eurohydro.com/publications/publications/APPLICATION CHARTS/GB/CHART-FLORA-SERIES-GB.pdf

What nutes are you using and at what strength? I don't see a plant that is being overfed,IMO I see a plant that is either Hungery(more N) or is not getting sufficient light. Being that the tops are a nice shade of green I would say feed them. What is your ph? If you are properly feeding you may be locking Nitrogen out. You want a ph between 5.5 and 6.1 for your medium. I disagree with the post that says soiless mixes contain enough nutes in them.

hi so high, thanks for reply, I'm using general hydroponics nutrients,FLORA GRO, FLORA BLOOM, FLORA MICRO, I got the feeding schedule from a site called GROW WEED EASY .COM my ph is perfect, the day I took those photos they hadn't been fed for a week, after feeding them they started to come around, they're looking a lot better now, I think you're right in saying they were hungry, i'm keeping a closer eye on them now, cheers. al
