Need help.. pics

Here's the deal guys..

the plants are TGA querkle at approx 3 weeks into flower. they're in 5 gal pots with ocean forest and perlite.. about a 50/50 mix.

The temps are 70-74 with the lights on but go down to about 66 with the lights off.

house and garden are the nutes and the plants are fed every other watering. R/O water ph'd between 6.3 and 6.8. mag cal supplemented when feeding

the only issue that I can think of is the humidity being quite low due to my region.

let me know what you think ..here come the pictures

any ideas? yesterday humidity was down to 20% with a 16% low

took pH and ppm of runoff today..

pH was 6.7 and ppm 630.

could the fact that we run half perlite and half soil have a difference of the pH we should be watering with?

Looks like nitrogen deficiency. What nute strength are you feeding the plant?

Might wanna bump your ppm up a tad . Or just some N

Whats your ppm going into the pot?

Last feeding was pretty low, around 800. Fed today with 1600ppm.. will post pics and report on how they're looking tomorrow.
