good advice needed pls, pics for opinions !

[f1bud]

got yellow tips looks like nute burn, just repotted to 15 ltr pots ( 3 gallon ) 600 watt hps in grow tent, proffesional soil mix only added nutes 3 times in 5 weeks twice at ten percent once at 50%, i am nearly 2 weeks into flower and the bottom leaves r yellowing a bit on my 3 white widows, my pineaplle chunk is just fine treated the same as the WW, the yellow tips were there from the beginin before nutes were ever added.
so i av added very litle nutes from the begining so dont no y im'e gettin wat looks like nute burn and how do i stop the yellowing without more nitrogen ? i will also av to start on flowering nutes soon i guess,, is there a chance that this yellowing is genetic as i had this identical on the last grow and the seeds r from the same batch ? coz my PC is growing just fine no problems wiv tip burn yellow leaves etc. !!! most peeps on here just say flush them, but they av just bin repotted and waterd wiv plain water in new soil ph to 6.5 with a tiny pinch of epson salts,, i fed the worst of the 3 WW wiv 50% nutes but the other 2 just got plain water to see if the fed one showed any difference from the non fed ones !

no guessing pls peeps if u can identify my problem then pls let me no but deffo dont need to here it cud b this or that so do this to it or the other,, to many different opinions on here and as much as i appreciate any help its not helping when peeps just guess. any good advice and i am all ears guys !!! thanx

looks super healthy to me...very very slight nute burn...the yellow tips do kinda give it away...some people would argue though that tips such as yours indicate good fertilization...or what you want to see...not necessarily a bad thing.

yeah just do a good flush with clean water, let it dry out for 3-4 days, then reintroduce nutes at 1/4 strength and you'll be good to grow

Appears you've over fed them. Do you have a ppm meter? What line of nutrients? What did you feed it last? You don't need to flush, its a slight burn.

Personally I'd do nothing maybe back off a little on nutes. I get a few brown tips once in a while its just from a tiny bit too much nutes. DO NOT PANIC and start doing crazy shit I would not even flush it just feed it a little bit less thats all. You have a very nice plant there.
