Ok they said soil I was wrong but no nutes either.
This is just overly simplified advise to the point it's basically wrong,... Mainly they are saying that putting seedlings into a very rich soil will be too muc for them, and that much is true,... But they should mention that the milder the soil is, the more nutrient poor it is and if it's like most dedicated seedling mixes (or coco) it's not going to have near enough nutrients to boost your girls along. They may survive, even look OK , but will be smaller, much smaller than they could have been potentially. That's what I mean about having your early growth veg' game in good shape. It's not as easy as it sounds mate, all you can do is chose your info sources wisely and try your best when growing, experience is everything!
For HF, I'd start feeding weakly in the first week, to get stuff in there and starting to break down... That's the catch with organics, that delay... With synthetic's, the nutes are in chemical forms that plant can take in directly; with organics, some need to be broken down and converted into those forms.. Only specific chemical forms are able to be taken into the plant....
Have a read on chelation, and humic-fulvic acids in these two articles located in the
Reference section....
I advise you to get a kelp product, a Silica product and some humic-fulvic, these will make a significant difference not matter what type of nutes you use...
What are your T's in that tent, high and low during a 24 hour period? Cold is a serious problem for auto's, especially dark hours... slow temps = slow nutrient break down and uptake, plus slow plant metabolism,.. all these combine to retard growth and as mentioned with auto's, always the clock is tic-tic-ticking away...
