Help please? Some issues i cant figure out.

Have a kush plant, about 3 weeks into flowering. Pics attached. Water run off pH level is 6.3. Starting to see some issues after starting flowering. I have a 300watt led 6500k light, and 4 100 watt 2700k led lights. I have fox farm trio nutrients and a mix soil 2 kinds of fox farm soil. 12 hours on 12 off. Water every 4 to 6 days as dirt drys and pot gets lighter. Not sure what the issue is but need to figure out asap if any one could help a rookie get this fixxed I would greatly appreciate it. I was told it was the lights to close, then I was told it was nute burn, then I was told 3 other things and no solution or told it was almost positive it was this.

Not enough info on feeding? A guess would be you fed them and it dried back a little too much.Fed again with no runoff allowing it to build up even more.

Just a guess.

,Its kinda tricky feeding soil that has food already like FF.

For future grows go with an inert medium and just feed nutes to some runoff every time.So much easier.

I feed with about half the amount of nutes stated, sledge hammer flush about 5 weeks ago before the switch to start flowering. Fresh water 4 to 6 days after feeding. Lights are about 2 feet away.

Temps 60 to 65 and the humidity is roughly 50 to 70

Its really just guesses at this point,could be light burn maybe.
The one pic shows really dry soil,
Maybe you fed when there was still lots of food in the soil?
I dont see you turning these plants around this late in the game.
How big of pot and how long has it been in there?
My usual fix is mix nutes to 1 EC feed to runoff every 2 days if the pot is more or less root bound.

Pretty darn cold for led lights,you want 75-85 during lights on.

Any Mg supplement added?
The green veins shows like a deficiency ?

Any pics from 3 weeks ago?

Was in a half gallon pot during veg, replanted about 2 weeks before flowering. Temp can be raised not an issue, attaching a pic of the plant about a week ago, only pic I have of it. Replanted to a 2 gallon pot. Nothing else added besides fox farm trio and sledge hammer flush. Only thing dying on the plant is the leafs, haven't gave it any more nutes since 2 weeks ago, was the first flower set of nutes, half of the recommended amount.

Sledge hammer flush after you transplant up to 2 gallon??Like a big flush ? Why?
So you up potted into fresh dirt? So that new dirt has organic food in it.
Im just going by what you've said,so maybe im misunderstanding.
Then you fed the new dirt?

And this,have you added calmag with the trio?

Honestly I would say potassium deficiency which will crisp your leaf edges and give them a burnt pattern. The reason I say this is the definition on all the leafs points to a deficiency the plant was feeding on itself and now is showing you it has nothing left to eat. I would up your food a and add in some extra potassium

It's mixed dirt, fox farm and fox farm older dirt, used before and sifted threw a screen. Did the sledge hammer flush before the transplant wasn't alone, I've used it before to flush the dirt of the old nutes. After about 2 to 3 weeks of regular watering in the 2 gallon is when I gave it the first flower nutes about half the amount if not a little less. First time using these lights aswell. Moved them to about 4 feet away now. I looked up the lights and for flowering it said about 4 feet for flowering. And no the cal mag I bought was damaged and still waiting for the new to come in.

I will try this as well. Like stated it's been about 2 to 3 weeks since feeding, and was the first flowering nutes I gave it. Didn't want to do to much with out knowing a good idea what it might be

You really don’t need to flush soil just water till a little runoff and step back. You are just washing away food and important microbe when you do that. And the plant still needs that nitrogen when it starts flowering.

Ok so its safe to assume it hasn't been over fed,low temp and too much light.A quick fix is mix up some nutes 1 EC ph about 6.2 ish add some epsom salts like a a gram to gallon ish and feed her.Wait 2-3 days and feed again to runoff.Dont let runoff get sucked back up.
About all I got,good luck.

700 watts of light for that little plant is an over kill, I'd be growing about a pound worth with that amount, so that's one thing , feeding her is the other without an excess of nutrients locking shit out

I usually have about 4 plants, only did one this time though. Yea I seen in a post on lights it's alot more then it should be so I cut off the 6500k light, and will give nutes today and see how she is in a few days. Also about to go grab some cal mag from the grow shop up the street. Possibly gonna grab a vivosun 130 real watt I think it was 300watt led full spectrum light. Will attach a pic momentarily

Just get a couple dollars worth of un scented epsom salt.Way cheaper and it will last forever.
