At a loss, funky plants :(

Greetings guys,
I haven't grown in a few years now.
Went with Barney's Pineapple chunk feminized and the freebies I got with my order. Bluedream, Chemdawg and Trainwreck.
I am using an HPS 600w, soil : biobizz all mix. Vegged for 3 weeks. Started flowering 2 weeks ago. Saw my first pistils this morning
But some of the leafs are weird.






So far they had one very light feed on biogrow, biobloom and topmax.

I did notice that I can see the roots poking out of the hole in the pots ( 10 litters)

Any advice is welcome.

normally when the roots come out of the holes at the bottom , the pot should be changed to a bigger one to give more space to the root but it is not compulsory it depend on how much you would like your plant and flower to grow hope this helped you

ps: nice little garden

The top pic looks like a severe nitrogen deficiency. If the roots are poking out the bottoms you should transplant now and avoid any root bounding problems. Don't go crazy with the nutes trying to fix the deficiency, just give them a slightly stronger feed. Or it could be a P def.

Thanks for taking the time to reply. I have all from Biobizz (biogrow, biobloom, Topmax and Fishmix) in order to help my girlies wich should I " boost"?

I last fed them lat Sunday, I ll wait till Thursday to repot them, roots are going all crazy, even reaching the water trays...

An even yellowing of leaves beginning at the bottom as shown , indicating a Typical Nitrogen Deficiency .. Your going to have to feed them alot more as they flower ...

Bumping this to thank you guys. I boosted the feeding (N) after a week the plants look great!
