Discoloration Of Older Leaves - Please Help

[smallaxe]

Hi everyone!

I'm growing Sour Diesel Auto - some are from HSO and some from Dinafem and some of them have started showing this discoloration of leaves.

I am growing them in Plagron batmix soil which should be full of nutes for the first weeks and they're in their 4th or so.

Also, this 'discoloration' or what you call it happens on older leaves in the lower parts of the plant.

Pics provided are the best I could catch and the one in the pic is HSO.

Any ideas what this could be?

Thanks a lot!

How is your ph both in soil and water your using to me it's a little N low but it's really nothing to worry about the lower leaves will slowly do this I'm going through the same in my grow .

Well the soil packaging says it's 6,5-7,5 and my tap water is usually around 7. When I add Plagron nutes I use it levels it to 6.5. So I think ph should be good. I thought it might be N deficiency too. Thanks!

Yep that sounds right to help the plant out I keep 1/8 strength N nutes going right through the grow it seems to work for me I'm in my own native soil compost mix good luck Smallaxe .... Keep in touch regards One Drop .....

Hey One Drop! I'm afraid adding a bit of N - in my case Plagron Grow didn't help! Some 'spots' or whatnot have appeared on both that plant whose pics I posted last time and the one next to it to which I didn't even add any nutes! Any idea what this could be?!

it could be a number of factors mate that's the reason I keep my N going right the way through to avoid this problem , the N I use is my Urine , how far into flowering are they some plants seem to use up the stored energy in the leaf as it changes into the flower cycle . My sergestion of flushing out the bag of growing media your using could help a bit as well it could of been still a bit hot to grow in causing N draw down where the media is still cooking and not ready to supply the goodies at the right time myself I make my own compost and this run suffered the N draw down due to my compost not being ready .
