Are Secondary Nutrients Important?

[tekneeqs]

Three different types of nutrients described: Primary, Secondary and Trace nutrients.

Why are secondary nutrients (calcium and umm.. 2 other) NOT found on any of my fertlizers? They are NU-GRO 20-20-20 and MIRACLE GROW ULTRA BLOOM 15-30-15. They contain all the trace/micro-nutrients (eg. Bore, Zinc). Why is this and how important are the missing secondary nutrients?

Calcium is really important but it's often plenty present in tap water, so depending on the hardness of your water, a nutrient that contains it might be overkill.
I think Silicon is another that you are going to want if you have soft water.
I add Silica Blast for both of those.

BTW I'm a bit offended by your new avatar, if you care to hear my opinion.

well you could grow without secondary nutrients
like wild ganja
but the plant will become a stronger and more healthy plant with them and give out better buds in the end
so i guess its up to you ,you could spend a few quid and have better buds or you could not bother and have nowhere near the same quality buds
in the end you get what you pay for if ya know what i mean
cheers all :)

How does my avatar offend u? It's a picture of a silicon-based doll that's fully clothed, chilling on her water bed with a spliff in her left hand (of course you can't see this in the picture lol).

If you can't figure it out it's not worth explaining. Never mind.
