Veg problems with pics. need some pointers

Girls In veg.
Temps are mid 70's to 80. Humidity 40-51%. Fans each side blowing through plants. most of the problems seems to be at bottom of plant but slowly working its way up. Tops of girls look good. I never had this problem before,but Im not sure if I have to many and not much light can get down below to bottom of girls.
Girls are anywhere from couple months old to a month old. In roots organic soil. I havnt really been feeding the last couple weeks, thinking they would get some nutes from soil,so just been using a little calmag. When I water I ph to 6.3. Soil ph is around 6.8.
The nutes I will be using are advanced nutes grow A&B,voodoo juice and b52 for veg.

Im using a 6500k T-5 4' 6 bulb.

IDK ur plants look great from the top, R the leaves that r dying only on the bottom of the plant where they're being blocked from gettin any good light, if they r then they might just be using up all their energy and dying on their own the plant may be fine, sure looks that way from ur 2nd pic.

U don't plan to switch to more of a red/yellow bulb for flowering?

food in soil would only last 4 ish weeks............

del..do they look like they are hungry? What do plants do when they dont get enough light at the bottom?? Im hoping thats the problem. I was going to start feeding again but wanted to make sure if this was a deficiency or not. I am crammed for space tho..Thanks for replies fellas

yeah i had a load drop out when i cut my light down to 600 watts..............

yea,I need to make some space in there and move a couple and see if getting light down there helps. Its driving me crazy ha

dvs,I think my hps are a red yellow. They were cheap hoods off ebay. 1000hps

im interested to see you run your ph at 6.2 as i never ph when using soil..............prefer coco now though.....

so...am i just not getting enough light or anyone else weigh in on what it could be??

no one else knows?? Or can give me any insight on my sisuation?

Ahh I gotcha I thought u just had those 6500k T5's u mentioned before but kool if u have an hps too. U could always try to set up some sort of reflective material in ur grow room to try and get more light for the bottom of ur plant, they have these reflector things u can get too with a light in em to set up on the sides or maybe just some mylar. U could even set up ur HPS light then move ur T5 lights to get the sides and bottom of ur plant.

I have 2 rooms. A flower room and a veg room. In the veg room is a 4' t5 with 6 bulbs. I had a veg box before that I lined with insulation board "celetex". they come on 4x8 sheets for around $7. Maybe I should go buy a couple sheets and see what happens. It seems like I just need to get rid of a few girls ha.
Hey queefbox,thanks for the great pointers. what would rollitup do without you going from form to form saying "look up plant problems" ha,dude come on. Obviously I already had an idea what it might be and was wanting to know about low light down below. If your not gonna post anything to help,why post at all? You think I would waste my time on roll it up but not do my own research as well? Way to get to 103 post queefbox.

Thanks for reply dvs

Has it been moving up the plant? Or did it stop at just a few? If it keeps going, and you haven't resumed feeding, that's likely to be it I would bet.
