Hey everyone, I'm running a single plant in a 3.5 gal bucket with 450w viparspectra led light. Nothing is really wrong with my plant except that it's starting week 4 of flower, and the the ppms are down in the 600's.. it's a sativa plant, and it seems to be doing great it's about 5.5ft tall with the bucket and I keep the ph right around 5.9-6.1. I use botanicare I use bloom and hydro guard I have calmag+ but don't use it because it doesn't have deficiencies. But like I said I had the ppms at 631 yesterday when I left, today it was 675 I diluted as much as I could but I watered yesterday and wasn't much room left in the res. Ph dropped to 5.8 brought it to 6.1 my ppms should be over 1000 at this point should they not? It's also not drinking tons of water. Maybe a gallon every 3-4 days. Roots look white. Anyone got a clue?
