Any ideas folks?

Autoflower grow, wk 5, canna pro soil, canna flores and vega nutes.

I'm feeding 5ml flowering nutes per ltr per plant every third water. The problem is only affecting the lower fan leaves for now. Have just given an epsom salts water incase of mg def but i would be surprised if this is the case considering my soil and nutes. ph is around 6. I've had similar probs in a recent grow but they started around wk 3 and it was never resolved. Still managed about 1.8oz per plant. Ideas please, thanks in advance.

No you are underfeeding. Time to make it 30ml per litre EVERY WATERING of flores , with a flush of ph'd(6.5) water every 5th feed to remove salts.

ah ok 30ml per ltr seems like a lot. I got the ratio from the back of the bottle but i appreciate that it may not be developed for weed

So did i and it says 3ml per 100. I feed my plants this way with canna nutes and they are perfect , green from top to bottom and not even a hint of nute leaf tip burn.

mine says 50ml per 10ltr (1:200) but it also says that when growing intensively i should be feeding everyday. hmm didn't read that bit till now. Will up the nutes and feed every water and see how we get on. Thanks mate, it does make sense actualy, one plant is slightly smaller and has darker leaves than the other suggesting the large one is not getting enough nutes.
