Hello , I am having a problem with my plants . New growth looks good , but lower branches having issue . I think it might be nutrient burn , but was wondering if someone could look at my picture and tell me ?

LED's 6 inches from tops
Room is a/c
5 x 5 grow hut (reflective mylar inside)
Lights off temp 70 F and 38 to 45 humidity
Light on temp 78 F and 38 to 45 humidity
4 week veg just started 17 days flowering
House and garden aqua flakes
Ebb and gro 2 gallon buckets
resevior 30 gallon
I use ph pen and also have ph monitor in resevior
ph 5.8 to 5.9
Bottle water (initial ph is 7.0)
ppm on initial water is 10

ppm currently is 1020
ph currently is 5.8

Grow Media (sure to grow inserts)

If I left something of the details out my apologies let me know and I will add the information.

Anyhow , here is the picture of on of the leaves hopefully someone can shed light on if I am right or is it too much N .

Thank you in advance for any help you can!
