Need Help please!

Hello, growing some what i assume is island sweet skunk.
All was going well during the vegetative state however about roughly 3-4 weeks into flower the tips of the plants leaves looked burnt (nute burn as far as I can tell.). So I flushed them 3x to be safe with Ph'd water, the run of was 6.4.
Then another problem occurred the leaves stems are turning purple and one of the branches leaves close to the bud was turning completely brown.

The rest of the plant looks relatively fine and the newer leaves are healthy, primarily the bigger leaves that have the burnt tips.I can take more pics.

Temps have been hitting a couple of times 90 degrees but that it about it when it comes to temps being unusual.

Please any help would be appreciated.

Id say you're on the right track if you've seen improvement in the top and new growth.
Just keep a close eye on it.
Dry it out.
If its starting to get wosrse in a couple days, or isnt any better, give it another flush.
You'll be fine mate.

If your newest leaves look healthy then I would let her be. You don't want to over care for her. I have been guilty of that when I first started growing. It will cause more problems than you already have. Give it a day or two and see what she looks like. She will probably need a light feed on the next watering after the flush.

It takes a few days for the plant to show what is going on when you grow in soil. The purple stems are from stress. Could be from the flush, the high nutes or high temps.

Try to keep the Temps down. It may cause it to herm later in flower if it continues to get hot.

Okay thanks for the help ill post more pics if it worsens in the next couple days.Just do not quite understand on what a light feed is.Is it 2/3 of the nutes needed for flowering or less?
And the grow is in coco.

Just keep an eye on it.
If its sexy in a day or two. Let it be a little longer.
If it isnt flush it again. Then dry it out, and wait.
Good luck

Thx Tim and Crouching gardener, much appreciated will update in a couple days.
Peace!

Okay update a large portion of the leaves are turning yellow.
The burnt tips seem to have stopped in progression on the leaves.
When should i continue the feeding schedule? and is it wanting nutes now because its drawing from leaves now?

Looks like light burn to me, what lighting? Just cut the affected parts from the leaves, should be ok! Leave the green bits!!
