Proper use of silica?

Is it safe to feed silica through harvest. Does it affect taste or flowers at all? I know its fed and used throughout veg, to build up plant. However I wonder after veg, should it be lowered in bloom or cut off alltogether?

last time at week 3 of flower for me

Interesting. What is your reasoning for stopping so early in flower, if I may ask?

i use gh armour si, silica..i know it sais to add it first then ad your nutes, but i use it as a ph up..i ad my nutes, then if ph is low i ad the silica in very small doses just to get the ph wright..i use it all the way till harvest with no ill efects..
does anyone else use it as a ph up rather than an aditive?

Interesting to know you have no ill effects from silica all the way to harvest. I never need it as a PH up. No matter when I add it PH stays between 6.0 and 6.5, which is ok for soil.

Silica is great for the end of flowering, and the entire plants life. It helps the plants fight bud rot, heat stress, water stress and a few others.

Hydro-gardens has some of the best potassium silicate I have ever used. 1 ml per gallon gives me around 90 ppm, majority of it being silicates. Try getting that with ProTekt or ArmorSi. Did I mention that it's only 20 dollars a gallon, instead of 40 for the watered down hydroponic shop stuff.

Read this article on silica. Should answer all your questions

yes it's safe from start to finish.I prefer feeding si on the very low side tho. 0.2ml/gal armor si. they recommand 1.25ml/gal. Lol. marketing bulshit.

silica is a micro , anything above 5 ppm is waste.

Simple answer: use in weeks 1-6 of flower (RATE 2ML per liter) this product fight disease but most of all it makes the plant strong and helps in cellular development

Why want run thru harvest? When want least of anything

Plants don't use glass for anything. Silica is just a craze.

I swear things are growing bigger and faster with silica than not. My recipe has been 1ml of botanicaire silica blast per liter or 4ml per gallon of water....every watering.

Ive heard that you should mix silica in a separate bucket then add the diluted mix to your nutes.
Also heard if you add silica straight in to your mix it will lockout your calcium.forming floaties of your calcium in the mix reaking havoc on sprayer or drip lines

i hope thats not true.. i add it to my mix last just to rais ph, it works as good as ph up in that case.. ive never seen calcium deficiencys or any problems using it as a ph up..but on the bottle it does say to mix it with water first, then ad your nutes.. if i use it as directed i end up using lots of ph down, just a few drops raise ph..

I mainly use protekt as ph up but its legit in other ways as well. Especially when its hot!

I think silica can be overused as it can make healthy leaves brittle. Personally, I use a light dose and pretty much stop after about the halfway point in flower.

I've seen it used directly in to mix with out diluting first and it forms like a whiteish floaties.was told it binds to the Ca and locks it out

What are you experiencing using protekt, when it gets hot?

Silica improves drought tolerance which may be what he means.

Ahh. I was wondering. I started using it in my garden last week, and we've got a heat wave going on right now. My broccoli has gone all wilty from the heat. I was curious if there was something specific he'd experienced.
