I purchased a pack of 3 seeds, and one of them didn't germinate. I must admit this is discouraging, and I believe reputable seed banks should address this by providing guarantees to us growers. I'm not wealthy, and when a seed doesn't germinate, it feels like I'm wasting money.
Regarding the fertilizers, they come in powder form, but I didn't see the option to measure in grams, so I used milliliters instead. The iron supplements I use are effective; I even found it strange not to have Plant Prod around here. It's a very affordable Canadian fertilizer that delivers good results. Many brands don't want you to know about this fertilizer. Look it up and let me know what you think.
Same thing happened to me man... me Hulkberry Auto is MICRo but that's cuz I LST it, didn't even Top my plant.. it just got pissed from me bending her over once. Idk what it is with the Hulkberry but mine is super small too.
