    Nitrogen toxicity?

    So he knows how to adjust the PH by knowing the base PH of his water tap/RO + the nutes he uses (and how acidic they're), makes sense but how can he exactly know the value of the resulting PH when you mix multiple nutes with the base water? Without a meter how can he know the base PH of the...

    Nitrogen toxicity?

    So right now, since i can't buy dem water, i'll stick with my tapwater, which is 270/300ppm (Probably i'll decant leaving water in a container for 24h) While my mix with nutes is about 870ppm. I use this pattern : Feed Feed Water,Feed Feed Water, and so on... Every Feed is 870ppm more or less...

    Nitrogen toxicity?

    I think i'll just cut CalMag out and that's it, the base ph of the soil as stated by BioBizz is 6,5 so i'll keep my trust on that... But dude so you say it's pointless to measure ph after each mix and adjust it? I'm not followin you, cause if that's true a lot of growers are doing all wrong...

    Nitrogen toxicity?

    My tap water is 300ppm, i just mix it with demineralized water to lower EC but most importantly because i'm scared of chlorine that's in every tap water of every house... I don't know if that's good for the plants,but keep in mind that i live near mountains, my water comes from the main source...

    Nitrogen toxicity?

    Damn i'll not use that then. Just for now i'll use only tap water or 50/50 tap and demineralized without adding calmag fix,i'll buy another one when i got the chance.... So can i use 50/50 without adding calmag fix or i need it anyway?

    Nitrogen toxicity?

    Dude i can assure you it's not overwatering, i can tell that because just before watering day the fan leaves are light and droopy,then a couple of hours after watering they stand back up again so maybe i should add more water. Also because right now i'm giving them just 2L each plant every 2...

    Nitrogen toxicity?

    No the ph should be fine i check it every feed to be near 6,5. For the watering/feeds i add 50% demineralized water mixed with 50% tap water + CalMag solution for that 50% demineralized water.... This CalMag if i'm correct it has a lot of nitrogen (4-0-0) along with som other micronutrients as...

    Powdery Mildew?

    Ey guys, i recently saw some white tiny points on my leaves.... My plants are currently at the third week of flowering and i'm pretty scared it could be PM. Since i wasn't sure of what to do i applied a solution for PM by sprayin the leaves; i should repeat the process 10 days after that...

    Ey, so this is my first grow, and here i have 2 girls switched to flowering 13 days ago, after they've been in veg for 5 weeks. As you can see it's pretty bushy under the screen,with fan leaves and new shoots coming out. I've already pruned a bit today and yesterday at the base of the...

    Best humidity level using LED?

    I'm using a LED so that's why i'm wondering this, i guess if i go with 28C in the grow room with 60/65% of humidity it should be fine, what do you say? Right now i have the humidity set at 45/50% because i'm too scared for mold problems, since most sites says that anything over 60% of humidity...

    Best humidity level using LED?

    I was asking this because from what i know, and now i get a little bit scientific aka trippin balls... The best photosynthesis of the plant is achieved when the leaves reach a LST (Leaf Surface Temperature) of 27/29 degrees,that's when you have normal CO2 parameters in your grow room (400/700...

    Best humidity level using LED?

    Ey rollitup, so i've been wondering if during flowering the humidity levels with a LED should be the same as with a HPS... 40-50% Do i need to have higher humidity like 60% just because i'm using a LED? Or there's really no difference and i'm just trippin balls?
