Thx again for all the help.
Not to dismiss someone's advice, but I wouldn't "weaken down" seedling soil. Unless you are using a soil with chemical ferts added to it I doubt that any kind of seedling mix would burn your plants, honestly. I've put seedlings into Happy Frog, Ocean Forest, and even Vermifire (An extremely "hot" soil) and had them turn out fine every time. Some people like to add perlite for "drainage" but the physics of that are iffy (Actually doesn't improve drainage, or have any effect on it really, until it is >50% of the mixture). If you want to add something to your soil I would mix in some water crystals, my best plants were ones that i started in soil amended with water crystals, helps to avoid overwatering, helps prevent soil compaction since they swell every watering and when they dry they leave tiny air gaps, which in turn DOES help with drainage, and it will help keep the roots oxygenated.
My point exactly, Happy Frog is a seedling soil and lighter than their main soil. Go tru canna pro at 1.4 to 1.6ec with your seedlings or the full foxfarms soil then youll see why i advised him away from the stronger potting soil to the weaker seedling soil. Really its like you just took a stab at basic soil knowledge and then when i said keep on the safe side by making it a bit weaker i.e. less is more well you know the rest.
You're actually wrong. First, Ocean Forest and Happy Frog are both different soils by Fox Farms, and neither of them are a seedling mix, so I dunno what you mean by "Ocean forest happy frog is seedling soil" because that sentence is just factually incorrect. Ocean Forest is their full strength soil, Light Warrior is their seedling mix, and Happy Frog is a 50/50 mix of Ocean Forest and Light Warrior. And Vermifire is even HOTTER than Ocean Forest. I didn't "take a stab at basic soil knowledge", I actually know my soils very very well, and given your last statement I will have to assume that you do not.
Totally, plus the vitamin b protects against stress and the cytokines in it have benefits at all stages of plant development. I would actually suggest foliar feeding with both kelp and aspirin (And amending the soil with both when moving into larger container), the benefits are enormous. Personally I am a fan of Down to Earth Kelp Meal
Just for the record I never told him to use foxfarms soil, he doesn't even have access to them where he lives, I was just citing those as an example of soils that are much more nutrient dense than his current soil that I have successfully put seedlings in without burning them (I have pictures as proof if requested), you just have to be careful. But Happy Frog especially will NOT "nuke your seedlings"
Did you just suggest using a seedling soil for seedlings!!! Ffs pass me that asprin im getting a headache....
A kelp foliar spray protects the plant from stresses of all kinds, and would help they plant adjust to the soil, and I don't think he necessarily needs to ditch the soil he is using, his seedling isn't burned, it's growing fine, maybe not the hugest jump in 7 days ever, but certainly not abnormally slow while it is establishing roots. Kelp isn't just about nutrients, it is about plant hormones, b vitamins, and Cytokines/Auxins. Foliar spraying seedlings with kelp and aspirin (Salicylic acid is also beneficial to plants under stress) is almost always a good idea, no matter what medium they are in.
Funny, that's how I wind up after smoking them
I agree that he shouldn't use additional nutes (although I just feel he should avoid adding too much N-P-K, whereas I feel a light kelp/aspirin misting would be beneficial), I also agree that in future he should use the Culterra seedlings mix, I just disagree that he should cut it down further, I think it will be perfectly fine without this mystery "weakening" agent.
