indeed you are finding out that neither of those mediums are going to make it from veg and through flower without feeding. this is why we all amend our soils with goodies to make sure plants have all the nutrition they could ever want!!
I hear you. I thought my compost would have enough nitrogen through the whole grow because it auto flower plants. Thanks. They’re almost 4 weeks from sprout.

well nitrogen is only part of the equation. the deficiencies that you're seeing are actually not nitrogen. Looks like you're having some pH swings, evident from all the twisting and turning of the leaves. those leaf margins that are yellowing look to be potassium deficiency now that your plant is starting to flower. and it's hard to say because these things are compounding each other. pH may be your biggest issue at this point....

Thanks. Hopefully since I started food they will get well. Notice the one plant on the left. That’s a Northern Lights auto. It’s still lush and green with no visual problems. The two that have yellowed are Green Crack. In the picture all are less than 4 weeks old.

I was afraid my compost would have too much nitrogen already. I can tell you this, the FFHF soil is doing much better after feeding than my compost soil. The plants smaller but the buds are filling in a lot better.

In the future, what do I do about potassium deficiency?

topdress a bloom mix about 2 weeks into flower. Dr. earth makes one that looks pretty awesome and it's not expensive at all. can get it on amazon prime for like 15$ or something i think. 1/4c for a medium size plant, mixed with compost and topdressed. should carry you through flower no problem.

Could you give me a run down on amendments you added to the FF Soil?
Here you go. Thanks for asking
I have since made a new batch including high P quano and fish bone meal but haven’t used it. My original is working fine, like I’ve said in another post I am now top dressing with fish bone meal and or the all purpose fertilizer that is in the picture and everything seems to be working fine thanks for asking

I’m curious. In your pic, I see some yellowing of leaves on the plants in the very back. I have that same thing going on with one of my plants. Do you have any idea why they’re doing that?
That is a plant That was about 3 inches tall when someone gave it to me it was pretty much dead I couldn’t tell you what’s wrong with it it might’ve had root rot the soil smelt funky but I did get over an ounce out of that little plant.

Update! In two days Feb. 24-18 my plants will be at 4 weeks from seedling. Even though the compost plant had a lot of yellowing when it hit the flowering stage it started out running the Happy Frog plants. It’s got some good bud in many places than just the cola. Happy Frog is budding but more airy and popcorning. The compost plant has the yellowed leaves. I’m very pleased and will use my compost, maybe mixing in a little Happy Frog on my next grow. Keep in mind, these are Green Crack auto flower plants. I will update when I harvest. That should be in two weeks or so. Happy growing!
PS: I’m using a Virparspectra Par450 led light running on all three spectrums, 24 hours a day and have only used Advanced Nutrients. .

The plant in compost finished faster. It looks like about 2 oz’s off of that one. Happy Frog in fabric pot, same strain, is running slightly behind but looks like it’ll be another 2 oz’s. This marks the end of my deal and I think I’ll mix happy Frog with my compost. As long as I can yield 2 ozs per plant over 11/12 weeks each time, I’m happy. Happy growing!
Here’s the cola from the compost Green Crack auto.
