what time to add nutes?

i heard like 2 weeks in. im in week 3 and it looks like i have acid burn on a couple of leaves. could it be acid burn or what could it be. i grow in doors and apic will be coming soon.

If you are in soil ya may not have to fertilize them for a month.

^ what he said...fox farms ocean forrest and happy frog has some good natural nutes in their products...i actually got some nute burn just from my soil when i transplanted...ended up not using any nutes for the 2 weeks of veg...and im using humboldt nutrients master a and b for bloom

ok im going through was seems like nute burn on tips of some leaves. is that root lock or is that nute burn i havnt added nutes.

I would assume it is slight nute burn from the soil. If it's not bad then it's not a big deal the plants will acclimate. But I havn't seen pics so I can't tell you, you will have to make that decision.
