ok, i have 12 6"- 8" plants with 5-8 nodes. Most of them have yellowing of the bottom leaves. is hasnt gotten worse, but i just recieved my new meter today which measures ppm. All my plants have a ph of 6.7-6.8. And all of the plants npk levels are 25-2-25 ppm respectivly. These plants are 3rd-4th week of veggin under4 4' 2 bulb t5. Should i go ahead and start weening onto some nutes? Everything else looks great with them, just looks like a nute burn or def, nute burn wouldnt be caused by those levels of nutes would it?

Also had a moisture meter on it, i was slightly underwatering them,
