Question about nutrients with Seed Starting Mix

Hey folks,

So I have started a few auto flowering strains in 4 inch pots with Miracle Gro Seed Starting Mix (basically zero nutrients 0.03-0.03-.03). They are now just about 10 days out and seem to be doing well enough. They all have their 2nd sets of true leaves and 1 seems to be starting 3rd set. Just to clarify if a plant has 2 sets of leaves there would be 4? We aren’t talking about nodes? Because I have read that you start adding nuts after 2nd set of leaves but also read after 2nd node appears. I have also read the more general after about 2 weeks add nuts.

Anyhow, my question is I am suspecting that they probably need some nutrients added after 10 days in this very light mix. Any suggestions/ideas? I do understand the autos don’t need to same level/amount of nuts as “normal” strains.

I had posted this on another forum without any replies. Cheers.

What do you intend to plant up into? Soil? Media?

If you feel they are ready for some feeding before transplant, give them 1/4 strength veg nutes at every other watering. Once you transplant you can determine what to do from there (soil, no nutes).

Yes two sets are 4 leaves. Plain water to keep soil damp for now. Some seedling soils have no nute charge. That works better for me Miracle grow’s is loaded at 3-3-3.

They are in the Miracle Gro seed starting mix with ~20% perlite atm in 4" pots. They about 11 days now out. The MG SS mix has only 0.03-0.03-0.03 on the package. Obviously need to transplant them but was hoping to get them bigger with a stronger root system before then. Once I do transplant I got to work with what is around here and it seems to me the MG moisture control potting mix seems like the best option at 0.18-0.10-0.10. I will mix this with perlite again I think.

So for now I am wondering if I should add a little nuts to them while they are still in the 4" pots in the mix with basically zero nutrients added…or maybe I just answered my own question?

Thx for the quick replies :smiley:
