Nice. They're getting there bro. Give them some Nitrogen, shouldn't be yellowing out like that. Check your ph make sure your not locking out before feeding. Also add some Cal mag for the brown spots on some of the leaves.
Matty, Tip burn is usually over feeding, however it can also be from hot room temps and lack of air circulation. Once tips are burnt, they stay that way. So, grower might have burned them weeks ago with an over feed. I'm more concerned about the yellow leaves. You need green leaves to help provide the energy to grow the buds.

Phosphate, Potassium, and nitrogen deficiency can also cause the tips to look burnt. Although without knowing OP feeding we don't know anything.

Since the flip they have been getting pH'd 6.3-6.6 straight water and fed every other watering with Shultz 10-15-10 liquid mixed at normal strength and then pH'd to 6.3-6.6. They have had one feeding with a finger pinch of Epsom salts since the flip. Lighting is 9x23W and 3x30W warm CFLs.

ph is fine. 20-10-20 would be a better ratio. Not getting enough nitrogen for my tastes and would explain the yellowing. On my last grow I mixed my grow nutes with my bloom nutes to get the leaves green. This grow, just keeping my Nitrogen at the proper ratio to insure health happy plants to harvest.
Bloom nutes is what is causing your yellowing. See it in mine when I only feed bloom...

A pinch of Epsom is not even worth it , takes at least a teaspoon to a gallon . As mentioned by prosperian , Nitrogen is going to be your friend and its best to use a high Nitrogen Veg feed during the first few weeks of transition into flowering . As well Cannabis uses a fair amount of Magnesium at this time too and the Necrosis along with the Nitrogen deficiency is related to a mag deficiency .. The nutrients are being redistributed to the last growth and in the end the damage is done but you can still amend somewhat .. Kudos and a happy harvest to you

Agree with the yellowing, last feeding (2 days before the pix) a concoction of Shultz 10-15-10 half strength MG 8-6-7 half strength and Thrive vitamin B with 1-1-1 at half strength was fed to them. If they are starving, why do they show burnt tips?

Outdoor growing has the highest light intensity, hard to beat the sun. Leaf tips are the most sensitive part of the leaf and the first to show signs of problems. If the problem is fixed, the leafs will still show the damage, forever.
Best guess, probably too much sun on a day the plant was dry or had just been fed and the tip burn presented itself. Look at new growth from this point forward for corrections. The plant is focused on bud production not leaf, so you should be able to coast to harvest as long as the new leaves are showing improvement.

They are indoors, but point taken about the leaves showing on older pre-existing condition

Sorry, keep flipping from two different threads with responses, got confused, lol. It's real difficult not to get tip burn in the last weeks of flowering.
So much energy is being devoted to flowering that anything that normally wouldn't be an issue in vegetative period, results in some type of damage in flowering. Least that's been my experience.
Stick with it, you are almost there!
