critical autoflower and bubblegum autoflower need some advice

Hey guys this is my first grow im using 2.5 gallon pots ffof and ffhf 50/50 mix woth 2 bags perlite i am using advanced nutrients i was just wondering what u guys thought about these critical bubblegum and one kish autoflower seeds from female seeds.nl they r in week 5 about a week into flower a few bubble burnt up some on me any advice or comments much appreciated

can you zoom in on the very small plant very close. need to see the leafs I think I see an issue there .

Best i could get thanks for th reply

First Grow and looking good

I'd trash the smallest one, not worth the effort

the extra space would give room to those that need it

great soil mix with perlite, but I'd be over cautious of giving them too much nutes

you feed the plant but can't support the root ball ..to supply maximum buds..?

due to the tiny pot, potup to a 3 usgallon minimum or

nute burn issues can be expected another 2 weeks

along with the associated anxiety

good luck

ps white pots suck paint or cover with kitchen foil

roots still don't like lights

Here r pics from tonight by the way im using 2 750 w marshydro reflector series lights

I was watering at a lil under half strenght with nutes all the way up until tonight the ones that showed sign of burn i waterd with straight water tonight and the ones that r healthy i increased the nutes a lil do u think this was smart i gave 6 ml voodoo 6 ml big bud and 6 mil b52 every gallon of water i mix( it calls for 2ml per litre)

The first pics i posted were a week ago i thought they were my most recent
