Worm Castings through Out Veg?

Hello I am planning on making a soil mix of-
50% Pro mix
25% Perlite
25% Worm castings

1 tsp of dolomite lime

Do you think the wormcasting's will provide enough nutrients for the plants through out the whole vegcycle (5-6 Weeks). Or would I still need to use liquid ferts?

That sounds like a long time to veg without food. Maybe you could look into some granular fertilizers that foxfarm and biobizz make.. You can mix that into your planters if you want to go a long time without giving liquid ferts. Make sure you get the pro mix without fungicide (BX?) and do get pro mix with mycorrhizae (mx?).
You should have some good soil life in the castings, as long as they are fresh. We have lots of locals that make worm castings around here.. maybe try to find some local freshy castings..
