Hmmm, I think you'll like the Chem's I just harvested... smooth, potent, dank aroma that fills the your lungs and lingers in the room. Wait a minute... Uhhh, actually I'll take those Alien Dawgs... :giggle
Very nice... Looks perfect to start bloom. :thinking I thought generally a drop in pH and rise in PPM's indicate that the plants are drinking more water and leaving nutes behind...
Here's a quick quote from the following link:The plants started sucking up the nutrients yesterday. I can tell this when I don't have to bring the PH down, but have to begin raising the PH.
When plants are growing in good light and warm conditions, the normal trend is for the pH to rise and we have to add a pH lower (acid solution). In cool, dark, short day conditions, it can be normal for the pH level to fall and we have to raise the pH with pH raise (alkali solution). As a rule, as plants feed, their root waste (sometimes in the form of ethylene gas) is basic and raises pH. In media based systems, microbes eat most of this up so pH is fairly stable. In water culture, root exudates raise pH, making the addition of phosphoric acid a regular occurrence.
I agree that pH Up raises your PPM's, but I was simply referring to the rise or fall in PPM's of the res during the week, not at res change...Actually the only reason my ppm goes up is 'cause I add PH Up and PH Down to keep it between 5.7-6.1. I prefer 5.8 as my perfect PH. This is the the PPM goes up.
I now understand what you mean and I agree. Initially if the pH rise is significant, that would typically indicate the mix is too strong... later on when the plants are larger with established root mass, the stronger nutrient profile, may just be dialed-in resulting in a relatively stable pH. I say relatively stable, because a slight pH drift between res changes can help nutrient uptake.Every time I have grown, as soon as the plants begin sucking up the nutes, the PH has began to rise on me. As soon as I get the higher dosage of nutes, the PH stabilizes. This is for 4 grows now that this has been true. I am sure you know more than I do about this Shady, but I just follow the way my plants have been in the past and try to keep them happy by this.
Because this has been true for 4 grows now, I wait for the PH to rise and then look at changing out my nutes for a higher PPM batch. I could be totally wrong in doing this, but my plants don't seem to mind?:free-character-smil
Excellent work! Beautiful shots... :sign0005: And I know what you mean... I feel as though I'm wasting my time without another light... I'll never be a full timer as big as Jack, but I'll take your lights when you upgrade... :giggleI am very happy with these results under 600's in hydro, but I look at JackMayOffer's RDWC System and know I am working just as hard, but restricted by medium and power. I gotta get a new place. I have my eyes open!!!
Very nice pictures! I'm not sure which I like more... :tongueout I guess the trailer since I'm getting married soon. Very interesting layout of the ducts and hood orientation. How hot was the first hood compared to the last one?
