Hi All,Merry Christmas and a Happy growing Year!
Got two mother plants,both 5 months old from seed,1xAK47 and 1xcheese. The cheese plant is a lovely colour of green,the leaves are silky to the touch and the branches are lovely and flexible but the ak47 is a very light green in colour(see pic), the leaves have a papery feel to them and the branches are very woody.I'm feeding them both exactly the same- Biobizz Biogrow NPK 4.0-3.0-6.0 with every watering(approx 4 days between waterings) and they're in Biobizz Allmix medium under an 8 tube T5 flourescent(38000 lumens) in the veg room.
I thought it may be a nitrogen deficiency so i'm foliar feeding the AK47 with Nitrozyme as well.I did have a problem with thrips on the AK only but i got rid of them about a month ago and the leaves that were affected turned yellow and dropped off but even the new growth seems to be coming out a light green colour.
Anyone got any advice or am I going down the right road with the nitrogen supplement?

NPK 4-3-6 is the wrong food to be giving both of them. You're giving them a high dose of potassium(K), which is mainly for flower formation. You need to change the ratio to nearly the opposite - something like 6-4-3 would be the right food. You're feeding them like you'd feed flowering plants -

cheers

No probs and good luck!

ps never believe what a company that wants to make a profit on their product have to say about, er, their product - they would say that, wouldn't they?
