Need an advice ASAP - timing issue

i planted 4 auto seeds from fast buds - orange sherbet, bruce banner, tropical cookies and strawberry gorilla BUT after 10 days i decided to throw out 3 seedlings because of stunted growth. only the orange sherbet was kept. problem is that now i have two weeks younger seedlings and i'm worried now that these time difference will cause other difficulties in the next weeks. i already topped the orange sherbet to slow a bit down its growth. (topping was successful) initially i wanted top all of them but now I'm not sure. what do you think? should i top the 3 late strains or should i keep them without any training with hopes that the three non-trained strains will catch up the topped one. of course, I'm also afraid that the non-trained strains could overgrow the topped one. what i should do? top the three late strains or keep them without training?

Just top the others as you would normally do and if you want an even canopy put the smaller ones on blocks in their drip pans.
