heat stress or nute burn yep ^^ it is something u should begin to worry about tho, not quite atm, but if it gets any worse it will be bad, and atm its not a good hting, slows growth, can u give us more info, like if u changed nutes or started giving nutes etc , and your temps

its more thna likely a nute problem rather than ph, the soil most likely contained sum, and when they are that small they need very little nutrients, like none added for first couple of weeks atleast, if it is nute burn then yes, you neeed to do a flush, but definately check ur ph first

what about thee chlorosis on the leaves? The yellowing between the veins..or is that the photo? My leaves looked like that and it was a micro nutrient deficiency.
Need more info on the soil and what nutes. If there wasn't the burnt tips I would say deficiency for sure but the tips... hmmmm.

Sorry, yeah the picture does it no justice.
The whole of the leaf is green just the very tips including the tips around the end that you can see in the photo on the right hand side that have turned brown.
They were repotted into larger pots last week with new soil, it's only 2 out of 10 plants that are exhibiting these brown tips which makes me think the temps and humidity are fine.
I've used a weak solution of a vegging nutrient just once a couple of weeks back, been only distilled water other than that.
Do you think repotting them into this new soil may of been too strong for them nutrient wise and they're getting burned?

yep, usually when you begin to do something different, and something starts going bad thatll be why, give it a good flush and see if they bouce back

If you feel comfortable about transplanting make sure the plantpot and the soil has good drainage. Ph balance the new soil before putting the plant in the new soil. If you are not totally sure of your new soil it doesn't hurt to bake it to get rid of any undesirable life forms.

If the new soil was hot and you fertilized yes nute burn for sure based off the quality of that pic. Flush em out you will be surprised how quick they bounce back . Start out with a low dose on your nutes and work your way up .

This picture doesn't say much(because it's poor quality) but usually brown tips indicate some sort of root problem caused by poor drainage or overwatering.

Your pH is most definitely off. I'm thinking it is too low.
The burn you are seeing is attributed to a nutrient toxicity as a result of other nutrients being locked out. The plant is looking for an electrical stability with the soil. If too many of the phosphates are locked up then the plant will wind up gorging itself on negatively charged nitrates in an attempt to replace what is being used up.
The reason this is obviously a pH problem is because you have both a nutrient burn, and at least a magnesium deficiency (as given by the yellowing of the leaves). Might be other micro-elements locked out as well.
What you do: Flush the system with pH 6.5 water. Use at least 4x the amount of water as there are gallons of soil. Do it slowly, each gallon should take several minutes. Try to saturate and drain.
This will rebalance the system. Then you need to top dress the soil with 1Tbls. crushed dolomite lime per gallon every two weeks and just feed through the top dressing. This will provide the micro-nutrients your plant needs and help create a pH buffer.
Good luck!

MAKE SURE YOU DO A PH TEST OF THE SOIL FIRST BEFORE BLINDLY DOING ANYTHING. Lime will bring the ph down.

Dolomite Lime raises the pH of an acidic soil...
Dunno where you're getting your info Bird. The lime was only suggested after a good flushing at the proper pH. I don't think anyone is espousing that this person do something blindly.
