Need Help

Hey guys. I am looking for some help regarding my babies. I am growing 4 afghan Kush feminized, they are on veg for about a month and a half now. I am using a 400w mh and canna nutrients. I was wondering if yellowing of the bottom leaves is normal. I have had to pick off quite a few of the bottom leaves as they turn yellow and crispy. The new growth and any growth below it before the bottom is nice and green. IS this normal?

Oh and where I have de-leafed the yellow leaves there is new nice green growth in it's place.

You should post some photos if you can. It helps with diagnosis of plants a lot.

I will try and get some pics but all I have is my shitty cell phone camera. Has anyone else experienced this with the bottom leaves? I am just wondering if it is normal or not.

i sometimes have this happen during flowering. How r ur ph levels soil and water?

I got it figured. It was a nutrient deficiency. Not enough N. Had a buddy come over who knows his shit.

Yeah it happens to me sometimes I think because of lack of light so I clip them off every other week or so. They just take up unnecessary nutes. Also I never take off more than 50% off the plants leaves at any given time.
