catching a problem early, burnt tips, curled + slightly yellow new growth

trying to catch this problem early before it gets any worse, on day 3 of flowering, day 37 total, not used lots of nutes to speak of just a basic 'all rounder' twice, ive also fed molases twice.

older leaves have burnt tips, but are otherwise keeping their deep green colour



and the new growth is coming through a little bit curled, and a little bit yellow around the edges



any ideas will be greatly welcomed, along with any solutions!

nobody able to help?

are those purple spots? If so lack of phosphorus

i repotted them yesterday and gave a good dose of organic nutes, hoping that will solve the problem.

just brow tips on leves
it could be nute burn
more info need light,nutes ,ph ,pot size ,temp

nute burn at that extent is nothing to worry about, the reason the leaves go yellow is because they've used all the nutes they need so there just trying to get rid of the rest, as long as it gets no worse than that i shouldnt worry too much, mayb just toan your nute dosage down a little. hope this fixes the prob
