2.3.2024: More of the same. "Plants" are getting bushier. 2 Nodes with the 3rd coming through. Look healthy. Top soil is dry but a few millimeters below is still moist. Once the 3rd node fully develops i'm considering topping but we'll see. Definitely can tell the Crystal Meth has a different structure then the Emerald Fire OG. I'll add pics at some point today
2.4.2024: Watered 32oz at 6.3ph. No run off.
2.5.2024: No water today. Plant is still super moist. Temp hovers around 77-79 and RH has been struggling to stay at or above 60%, even with the humidifier on and the inline fan speed at 2. I've increased the humidity output with the goal of getting it to the 60%-65% range. Leaves are getting bigger and everything is nice and green but i'm surprised at the lack of vertical growth. Its only day 17 from seed so we've got time. Just raised the light to 14 inches from soil and increase power to 50%.
2.6.2024: Moving along nicely. Plant is a little stubby. Nodes are tightly spaced when compared to the Emerald Fire OG. Perhaps thats just the difference in genetics? Raised the light again to 16 inches from soil with the hope of inducing some vertical growth.
2.7.2024: No change to current state. Struggling for lower shoot development due to fan leaves blocking light access. I couldn't help myself so i clipped the single leaves on the bottom of the plant. Probably a big mistake but it'll be a learning lesson if it comes back to bite me. Not much change in vertical growth so i'm thinking about raising the light an inch or two to see if that will help them stretch. Watered 64oz of 6.3ph. Small bit of run off, ph also at 6.3.
2.8.2024: Day 20 from seed. At the moment, the very small haircut i gave the plant didn't seem to have any adverse affect. Lamp at 14 inches from top of the plant, still at 50% power(75watts). Fan leaves are nice and full but rather stubby without much outward growth so I can't really LST or even leaf tuck. There are 3 sets of shoots that i'm struggling to give ample light. Not sure when/if to increase power and/or change height.
2.9.2024: Day 21 from seed. End of week 3. Plant looks healthy but leaves aren't as flexible when compaired to prior days. Wouldn't say crispy or brittle, just a little firmer to the touch. No nutes given yet as the FFOF still has amendments the plant is using. First sign of sex showing too.
I really appreciate your grow diary!! I'm on first grow and alos using the xs1500pro and everything was great but I also notcied the white tips around week 4/5. I've searched high and low for other users with this light. Right now I have it at top of the tent on 100% so about 30 inches away from tallest plant. I did have it about 18 inches on 80% but definitely had some light stress going on. I would like to run a couple few plants at different stages so that is why I'm testing the light where it is. I've noticed several users of this light reporting white or yellow tips on top growth. I'm also running 20/4
@Heretic, i'm shooting from the hip here but i'd guess somewhere in the 375-450 range. At the time of this response, i'm at 12 inches from top of the plant at 50% power or 75 watts. if you check the light's specs, 50% power at 12 inches should be somewhere in the 400 ppfd range.
