I’ve had a lot of help from posts, yet I seem to run into ta number of differing opinions on when to add nutrients. Here is where I stand now:
I have three seeds that sprouted, out of five, and now are ~3" to ~4" high, each with cotyledons and the beginnings of the first set of real leaves. They are six days from germination and in Jiffy Pellets, using just water.
The strain is Strawberry Kush from the ILGM seed shop.
While the three sprouted and grew to that height in roughly two days, they are now happily hanging out under a 24W, 2’ 6400K Spectrum Jump Start T5. I haven’t really done anythiing except ensure that their soil remains most and that they have the light available.
The nutrients I have on deck are Nutricare Pure Blend Pro: Grow, CalMag+ and Liquid Karma. The nutrient packaging suggests no PBP for the first two weeks, but does say to add a mild solution of CalMag+ and Liquid Karma to the water.
In grow guids, both here and other sites, I’ve seen opinions where there should be nothing in the first two weeks except water and light, and I’ve also seen where it is suggested that a mild nutrient additive is recommended. There doesn’t seem to be any consensus, but these plants are still just little ladies, still working on sprouting their first set of leaves.
I want to do what is best for their successful growth into young plants, so I thought I would pose the question here.
I am not sure what type of nutrients, if any, are derived from the Jiffy Pellet, and I am not sure how much nutrients are stored in the cotyledons.
I don’t want to be overly zealous on starting the nutes, but I also don’t want to starve them, or limit their development either.
Also, is the single 24W T5 good enough for right now? I have a Platinum LED 600 ready to hang, but I sisn’t want to go from T5 to LED too soon, either.
All suggestions welcome. Thanks in advance for any advice.
