Bottom leaves continue to yellow

[hazelsgarden]

Growing blue dream strain which germinate on 12-26 and around the 3rd week ive noticed the lower leaves keep turning completely yellow and the rest isn't a deep green that I feel they should be. Soil ph around 6.5 and for the hell of it i even tested my water and to my surprise everything was normal there too. I've been fertilizing with 1 tsp per gallon FF grow big every other watering. I'm thinking it's a nitrogen deficiency since I've read that blue dream is a heavy feeder. So maybe I need to increase to, 2 tsp per gallon? Only other thing is maybe I started fertilizing too soon? I started once i noticed 5 or 6 sets of true leaves. Appreciate any advice

I'd up that fert. to a tablespoon possibly more

Foxfarms says normal feeding with Grow Big is 2-3 tsp per gallon, every other watering.

I’m just double checking here as grow big should have plenty of N for your plant.

There are two fox farm products used for veg, Grow Big and Big Bloom. Big Bloom is a mild low nutrient organic “tea” that is very mild. It’s great stuff, but isn’t enough to feed your plants,

So, I’m just making sure that it’s grow big that your using? I really wish fox farm would rename the trio, it confuses people all the time.. (big bloom is NOT a bloom nutrient) Tiger Bloom is the flower nutrient, big bloom is used throughout the entire grow..

Yeah it's grow big 6-4-4 that ive been using

6-4-4- should keepem nice and green. This does look like an N deficiency to me, I'm not sure why though, you seem to be on the right track...

Any chance you have PPM pen to read PPM's of your feed? What soil are you using (I'm guessing Ocean Forest?). Many of my young plants take a week or two to become acclimated to the soil and can be a little finicky to start. I'm thinking its probably hot soil causing some issues for such a young plant.

No I don't. Should I invest in one? It is the lowest amount it recommends to feed, but I figured I'd start with that and then gradually move up. Just wanted to have a little more confirmation before I start feeding it more nitrogen

Nahh, you can live without a PPM pen.. I'm thinking your in great shape man. I do the same thing you do, feed easily and gradually increase... It's a smart way to go as its always better to underfeed than to overfeed. (IMO)

Think your plants look great and will take off soon...If you want a PPM pen, it doesnt hurt and its nice to know whats in the water and your nutrient solutions. You can get a cheap one $15 or so that wont be super accurate, but it will let you know if your off in the wrong direction.
