What's Wrong with My Mum? Pics Attached

[lince]

After I took 6 clones out of the plant the leaves started looking darker, I don't know if it's a nute problem or something else, but I have checked several sources and couldn't find an answer. I'm not really worried because I'll probably get rid of the plant soon but I'm curious.

Here are some pics:

are you spraying those when the light is on?

Well I only spry to use the neem oil but I always wait until the lights are already off, anyway it could be possible that I did it once with this plant, not 100% sure about it. Could there be any other reason for those symptoms ?

they need food, that yellowing is from lack of nitrogen.. Hit them with some veg food and you'll see a difference within days

Well, I was looking into the N def and found that it may actually be molybdenum def, anyway I watered the plant with some biobizz grow and bloom nutes and I had to add some sodium bicarbonate to get the ph up (never used it before but didn't have anything else). Lets see if she recovers

Yep I agree with max316420 looks very much like a nitrogen deficiency. If you are using straight pro-mix keep in mind there is zero nutrients in that stuff

and with promix WATCH your ph cause as it breaks down it become acidic

The soil used is biobizz all-mix. Now the fut is served so lets see if the leaves get better in the next couple of days I'll keep feeding if she gets better.

That makes me wonder... Do you have to stop feeding in order to take clones off the plant ?
