Well best amd probably only way is to have an ec meter. Ppm's are converted numbers from ec thats measured and differing from manufacturer the ec is multiplied by 500,600 or 700 to get the PPM's

Hello community! I broke 2 branches this week. The first one happened by accident when I was draining the runoff, and the other when I was bending it.
And today I came across a video where the author explains that silica can cause brittleness of branches. Does anyone have experience with silica and have you experienced anything like this? I add potassium silicate with each watering, at a concentration of 15ppm

Nutirents for hard water
Question regarding the correct fertilizer amount. Advanced Nutrients. If my water already has a high EC of 0.75 I use less base fertilizer (Bloom A+B). But do I also reduce the amount of additives like Voodoo Juice and Sensizym, etc? Is there anyone here with experience with AN?

TDS education needed please x
Hi gang. Have a query around TDS. My girls have had their second nute feed today (using alternating method) of GH products at 50% conc. The TDS of the mix (PH 6.3) was 500 and fed enough to gain around 10% runoff. This tested at 702. Acceptable or not? More nutes next time? Thx x

What's the proper way to measure ph?
When checking ph levels, is it supposed to be done before or after you put the nutrients in the water? Or both? I'm using Dasani bottled water and it has a ph of around 6.8. After I add .8ml of both Humboldt's Secret parts A&B, the ph drops all the way down to like 3.6-3.8. Help!

How do you know a plant needs PK ?
Last time I gave them 7ml of Pk 5-8 (7L pots) and I burned them. Probably the water already had too many nutrients (mineral water + osmosis water). How do you know if they need this extra Pk or not ? Is there any sign ? Thx !

Water Hardness Gives little room for nutes, replacing it with distilled = way more nutes?
My tap water is at 700EC (very hard), and I add nutes normally until around 1000EC, which gives little room for nutes, if I replace with distilled water, can I go up to 1000EC with it ? (gonna be a LOT more nutes).

Slow bud grow
Why is my bud size growing very slowly by the end of week 8/10 and I don't see very many trichomes? Should I add fertilizer or reduce the amount of water? Should I defoliate again?

Why does coco nutes often only have one A B blend, instead of 2 seperate Veg and Bloom blends?
I personally use Plagron nutes in coco, hence I use the same A+B bottles for veg and flower. When looking at nutes for soil they have the 2 different bottles for veg vs bloom. So my question here is why does it seem like some coco lines(plagron, canna) only have 1 over both?
