What kind of nutes are you feeding them?
Burned refers to nutrient burn, not the lights.
Too close to the lights would leave them brown and crispy.

Looking at a chart it could be the lack of Molybdenum.

molybd.jpg

A Molybdenum deficient plant will exhibit yellowing necrotic leaves from the tips inward, with necrotic lesions present from the tips inward. A very distinctive feature is that it occurs in the middle of the plant. It also may spread to the rest of the plant if not stopped, eventually killing your plant.
Fritted Trace Elements may be added to your soil mix as you prepare it for planting. A good Hydroponic nutrient should contain ample micros to get your plant through its lifecycle.

I only add nutes every third watering. Just ph'd water inbetween.
When you moved them inside, were they in pots or did you transplant them?
What kind of light?

NOBODY can say what the problem is WITHOUT a look at the whole plant and closer pics of the effected area!
Pics of some leaves removed give those with the ability to give real answers, almost nothing to go on!

I'll bet dimes to dollars it's NOT a micro def!

Pic of the whole plant and the effected area!

I've never seen an underfed plant that looked like yours. Something is clearly off so test your soil and know. Maybe salt build up in your medium or some form of nutrient antagonism. So it goes, figure it out and correct for your next grow.

pH problem! Needs Ca/Mg too. Low Micro/some Macro nute problems from underfeeding and pH.

Add a Kelp extract to your feed - Age old or Maxicrop seaweed are real good ones (Micro's, B-vit's, Plant hormones and Amino acids all things that you need, that will aid in recovery)

Light leeching of the soil...Water to run through and pour another 4 cups in. When it returns to needing a watering. Water with nutrient and Ca/Mg at full strength - CALi - MAGic from GH is good stuff - You want the iron it brings to the table too. This should be pHed to 6.8 for you till harvest. (At 6.5 your right at low pH range for a cpl of nutrients to be up-taken properly in your soil/you have a soil that is running to low a pH.....DON'T bother attempting to "fix" the soil.

OR (and better)

Simply water with straight water with the Ca/Mg pHed to 6.8 for 5-7 days and restart feeding at 75-100% nutrient strength (Just what ARE you feeding with) and feed every other watering - NOT every third.....You have low micro's too.

So, feed more, add a kelp and a Ca/Mg product and pH at 6.8 to hold a better pH. (Ph to 6.5 for veg and 6.7 for bloom in the future)

Next time add around 1/2 cup of Dolomite lime to your soil (whole bag of soil and mix well) before use.
