Auto Buddha - 120w LED

Been awhile since I've posted a thread, been lurking around I guess lol.
At the moment got a few seeds going under a 120w led, all around 1 week old or so. The oldest is a 2 week autoflower by Buddha, just one of the seeds out of an assorted pack.




Lowest leaves turned yellow and are almost falling off, since that I started feeding some 7-5-6 nutes. Even after this, the second set seemed to start getting yellow tips, so i raised the light to around 15cm away. I'll see if they improve... Could it also be because the plant is going into flowering? As I've heard that sometimes they take nutes from the first fan leaves.
cheers

Hey man, are you ph'ing your water before you feed it to them?
My guess is there is something wrong in that department. Do you have a soil ph meter?

Thanks for the reply, I haven't had any pH strips for a while now so I've not been able to, and my friend doesnt have any anymore. I remember last time the water was around 6-7 and it's coming out of the same tap as before.
I must say that since i raised the light i've noticed an improvement, the next set of leaves have hardly yellowed, and all the new ones are a perfect shade of green. I'll update with more pics tomorrow, and you can let me know what you think

Here's a pic from today! She's growing, and has started to smell pretty nice
