I am using a sun system lec lights in a 3x3 tent.

The exhaust fan I have is more than enough to keep air circulating but light possibly too hot. Anyone know what I can do to have my lights flush with the metal bars (as close as possible to metal bars)?

I would fall back to

1: this looks like a cal issue, especially since it starts shortly into flower, and it’s not the first run this has happened, OP stated he’s using distilled water, unbuffered, normally your City water would have cal already in small amounts, for organic I use 1tbs gypsum per gallon of water as well as 1 tbs epsom per gallon of water, weekly after week 3-4 if I start to see any cal def I up to 1.5tbs of each

How close are your fans to the plants? Windburn is a possibility if you’re trying to use an abundance of fan power to keep the tent cooler, even if they are oscillating it’ll dry out the leaf surface and start to taco / canoe up similar to how leaves look from light / heat stress

ould be many other possibilities, what’s is your medium, temps day and night, RH day and night, etc any additional information can help narrow it down

What are you growing in ? And what are you feeding ?
The only thing watering with distilled or RO water is gonna do is require you to provide the things that are present in most tap water. For example, some tap water will eliminate the need for cal mag entirely.
Anyway, list your grow specs and I’ll tell you what the issue is….or at least try,
Leaves can fry for lots of reasons…..most of the time it’s from too many colorful bottles of overlapping nutrients.
Once you lose all the leaves, the buds are not going to progress in their usual fashion.
You need to figure this out asap and make the changes needed to keep your plants green and healthy through flower…..only then will you see the potential of whatever strain you’re growing.

They are in soil.

How much and how often are you watering them?
What sort of soil is it as it looks very orange?
Stick your hand into the soil about 4 to 6 inches deep and I'll bet your soil is soaking wet.
Do the pots feel heavy?

I am having a similar problem. Is there anything I can use to help flush out salts? I usually flush out with rain water I collected. I am finding I have to flush out my plants at least 2 times during each grow plus the flush I do a week before harvest. Is it normal to have to flush out so much. Part ot it may be do to the grow bags I use. I try to fit a truck load of plants in a car size tent.

I am using 1 gallon grow bags for most of my plants 2 gallon grow bags for 3 plants and 5 gallon grow bags for 2 plants. They only thing I see different is the bigger the pot the bigger the plant. The smaller the pot the more often I have to water even tho the plants are smaller in a gallon pot. All of them keep getting nut locked. I tried something new today when I flushed out my 5 gallon grow bags I put two 1 inch high plastic straps in the water pans to keep the bags from sitting in the runoff and sucking it back up into the bag. Never ending joy learning to grow. You think ok I got this down to a science now then it all goes to crap and my plants tell me know you don't buddy 😉

You’ll never get a correct diagnosis without someone knowing all the variables of the grow.
Maybe I missed certain details, but the only info I’ve gathered is:
-growing in soil…..there are many different blends of soil, from heavily amended to completely inert. Need to know the name or brand.
- You’re watering w/ distilled water. This means it doesn’t have any of the micro nutrients present in most tap water…..for ex: you’ll need to provide calcium and magnesium for sure. You can use a bottled cal-mag product or an organic option like gypsum powder & Epsom salt.
- You’ve fed a couple of teas……what was in the tea? And are you feeding anything else?
These missing details mean any advice you get is going to be a guess, at best.
I’ve attached a chart that shows what and when a plant requires during veg and flower. It was my grow Bible when I started.
