Looks like you have minor heat stress, 1000 Watts is a lot.. and at the incorrect distance could do more harm than good. You can up your pH to 5.5-5.8 range. If you’re feeding nutrients I’d stop now. Only use water until she’s recovered as growth looks stunted slightly

Hi there! If your pH is really around 5.0, you're slowly but surely killing your babies! Make sure your waterings are in the right pH range (6.0 - 6.5). We're missing some crucial informations here : what nutrients have you been giving to your plants from the beginning and at what frequency? Do you check your Ec/Ppm levels every time you feed them? If so, what was your last measurements? What's the distance between the light & the plants? As an emergency move, I would increase this distance, flush the roots for a couple of days with correctly adjusted pH tap water (and maybe some stress-recovery product like Biobizz Alg-a-mic), carefully remove the dying leaves and see what happens ... Also, if you're able to lower down your temperature by 2 or 3 degrees, they might recover faster. I'll be around, good luck with these babies!

It's not nutrients deficiency. Your pH is a little low, try upping it to 5.5.
As for nutrient strength, how can we know if you don't post any data regarding what, how much, and EC/PPM levels of what you are feeding.

Brown spots on bud site leaves?!halfway through flower and now in week 6 flower one of my plants is showing some large brown spots on only the upper leaves. I’m not sure if it’s a light or ph issue as the light is close. I stopped cal mag and some nitrogen this week but spots were showing up before.

Does yellow leaves with red tips mean my plants need more nutrients or less? Jacks 3 2 1 on AutoWeek 8 (flower) top leaf tips are reddish and the leaves are more yellow than green. Does this mean that my plants need more nutrition?
I am using Jacks 3 2 1 for two autos and using it at 65% strength (650PPM / 1.2EC). Should I goto 100% at 990PPM / 1.9EC or 50% to 550PPM/1EC

Why one of the plants looks like is being flushed when I still have more than one week until the end of the grow, and I didn't start the flush?I'm growing the same strain from the seed pack, and I'm more than a week away of finishing the grow and one of the plants looks like is being flushed.
Both plants have received the exact same treatment, but one looks like is being flushed.
What can be causing this problem?
