Is yellow and brown tips anything to worry about??

Ingoing ph is a tad low, but how are you testing the runoff? If you're using those color-coded ph drops, the results are skewed by the tinting of the runoff water, making them basically useless for runoff.

How long have they been in the pre-ferted soil? MG 3 month formula lasts about 6 weeks before you need to start adding half-strength nutrients, but I have no clue how long the nutrients in the Plagron lasts.

How long have they been in the same pot? When you transplant, (if still using the Plagron) this will somewhat replenish ph buffering and nutrients.

Hi Rusty hope your good !

I am test the run off with a ph meter , using buffer 7 to test my tester ..

It will be week 3 tomorrow in the playgron growmix with perlite soil , They was in 2ltr pots for a week then transplanted into 14ltr pots two weeks ago ,
The plants are about 18" tall , does this seem small for a plant thats 3 weeks old from a cutting ?? Also the tips are still rolling right under , also some of the new growth
