8/10 Monday. 12:05AM FULL RETARD MODE ACTIVATED 8/10 MOnday - looking good needs water will ask Grok: For your Fast Buds autos (RF3s + Mendo Frost) at roughly week 5 in coco, target an incoming EC of about 1.2–1.6 mS/cm (roughly 600–800 ppm on the 500 scale). 8/11 4:30am 550 PPFD is solid for where those plants appear to be. Looking at the photo, you’ve got a clean, well-organized Spider Farmer tent with healthy-looking plants in fabric pots (plus the smaller one in the white pot). At 45 W per light (90 W total) and hitting ~550 µmol/m²/s, the efficiency is actually pretty good — modern diodes can deliver that intensity when the lights are relatively close and the footprint isn’t oversized. Quick context for that PPFD • Current stage (looks like mid-to-late veg on most of them): 450–650 is a strong sweet spot. You’re right in the middle. • You can push a bit higher (600–700+) if you want denser branching and tighter internodes, but 550 is already productive and lower-stress. • Once you flip to flower you’ll generally want to climb toward 700–900+ (depending on how the plants respond and whether you add CO₂). A few practical notes • Height & uniformity: At only 90 W total, the distance from the canopy is doing a lot of the work. If the outer edges or lower plants are noticeably dimmer, you may need a slight height adjustment or to rotate pots so everything stays even. • Heat: 76 °F and 48 % RH is comfortable. With only 90 W you’re not fighting heat. • Dimming headroom. The plants look happy — good color, no obvious light stress or stretch. You’re in a good place. If you want to share the exact model of the lights or the tent size, I can give more specific height/PPFD targets. 8/11 2:29PM these lights are so efficient and so good that I had to turn the electricity back each light is now down to about 40 W each so 80 instead of 90 Ish. I didn’t check the PPFD rating so I don’t know what the light measurements actually are, but I know keeping them at 40 each so a total of 80 W is very good. I raised the lights out there about 12 inches maybe a little bit more about 14 inches high off the top of the plant but doing good so far my EC was 1004 on whatever scale that is I’m using from 900 to 1.2 is what was recommended for EC. 8/ 10:48 AM I don’t really remember how to use those art supplies but my plants are starting to look nice and bonsai. One of them will be shaped like a snake. It’s gonna look really good and self supporting. The other ones are pretty good. These are gonna be a nice decorative grow. I should get a lot out of them too starting to flower fast buds always has the greatest staff. I mean there their plants are always the best. They respond so well to everything, especially all my mistakes they always recover. 8/13 12:47AM The two that are a touch pale are probably the ones you’re noticing. In coco that’s usually one of three things: Mild nitrogen hunger (common once they start really taking off) Cal-Mag demand ramping up (especially under LED) Or just the natural variation between the RF3 and the Mendo Frost phenotypes A light Cal-Mag bump or a small nitrogen nudge is the smart move. Don’t jump on it hard — just enough to bring the color back without pushing them into dark green and locking out other things. You’re already dialed in enough that a gentle correction should fix it quick. 👻👽 Your light setup is the real story though. Running two Mars Hydro TS1000s at ~40 W each instead of one at 80–90 W is a classic low-heat efficiency play. Same total photons, way better distribution, and almost zero heat load. That’s why you’re getting this kind of growth with almost no thermal stress. The plants are loving the gentle, even intensity. Dropping from 45 W to 40 W each was the right call — 45 was just enough to start pushing them. 👻👽
