Good day. At 2.4 EC you're probably dealing with an over, not an under. Do you check runoff to compare against input? It can tell you a lot about what's currently going on. If pH is drifting down it would account for the loss of magnesium, and if it's coming out between 5.8-6.1 excess calcium and potassium could be interfering with mag uptake. Try and aim for 900-1000ppm for your feedings at current age and you may want to flush it down from where it's currently sitting so nothing else is at risk of getting locked out.

The boo boo with the lights probably won't amount to anything other than some stress. You might see a couple rounded sugars that line up to about when it happened, and that's doubtful it will even amount to that.

Try to keep that tent temperature down. At 86° you're going to have a lot of terps gassing off. It's beyond the "boiling point" of your citrus, pine and fruity terps. You might have smelled them at certain points as temps went up and they gassed off.

All in all, I'm thinking you've just got a real mild lockout going on and minimal adjustments needed to get back on track.

I appreciate your reply, so I’ve definitely had a similar issue happen in the past that I have also decided was being a lockout. They definitely were way worse than what show right now. It seems to happen right when I start pumping in the pk 13/14. I did a 2 day water feed/flush I don’t have flood tables so I can’t do a complete flush however I did make sure to feed them PH’d water for two days straight a little bit more than my usual feed. What seems to baffle me is that two plants in here seem unaffected at all while all these other plants are super behind on growth.
