Did I burn them?

I am in the fourth week of 12/12 under a 1000w and a few of my ladies are looking a bit nute burned? I am using the fox farms trio and 1 tbs molasses. I started using 1/4 strength tiger bloom and have worked my way up to full strength general feeding. The lower leaves seem to be nice green and healthy so I'm a little confused.

Any help would be much appreciated.

I made a very bad mistake last week myself and thought my season was over, I used too much fert and other shit and fried my gals! Flush, flush, flush...make sure the runoff from ur plants is a light yellow similar to urine and not dark, if it's dark there is too much salt buildup and you need more water. Question: hydro or soil? There is a big problem using molasses in hydroponics but in soil it just aids in microbe life expectancy, use too much and it gums up and chokes off aerobic respiration of the root hairs.
Also, Fox Farms makes good plant supplements but when you think about it, Cannabis needs very little nutes to thrive and it's easy to overuse and that my friend is what has happened, along with ur Indicas showing lightburn. Flush them.

Looks as if it could be multiple issues, Heat, little nute burn, deficiency ? anywho keep track of how much you feed, I purposely take 1 clone out of each batch to ABUSE by overfeeding. so i can have an Idea on How long and how much itll burn.

I'm using happy frog soil, PH is roughly 6.3 after I flushed them. The water was quite yellow when I flushed. Veg nutes were used up until two weeks into 12/12, I haven't used any of the solubles.
Heat is definitely a factor, I haven't gotten my 6" ducting yet, so temps are high 80's even with my 530 cfm fan at full speed.

So, are they burned or is it underfed and starving?

I snapped two quick pictures after lights out.

I use grow big all the way until like 6 weeks into flowering, especially with the leafier strains. One of my strains actually uses double the grow big in flowering then it does in veg. I would hit them with 1-2 teaspoons of growbig at least every other watering if not every watering. The N they use in growbig is easily washed away and has to be replenished frequently
