Guava Auto - 2x2 - 150W

infamousdro This week I've been experimenting and trying to dial in the DLI/PPFD by changing light levels and raising or lowering the light. I've been following a general chart for Autoflowers and optimum DLI and basing my numbers off of that. I've been wondering if the leaf color looks good or could be a darker green. I plan on bumping therm up to 1/2 tsp per gallon of each from the Bloom Trio. My VPD is pretty dialed in for the most part, sitting at .8 or so for most of the day. I have a cheap warm mist humidifer which helps keep the temps elevated as well as the humidity. I can't wait for the explosive growth.

infamousdro I pH'd my runoff for the first time on 4/11 and found that it was coming out extremely high for what I was inputting 6.4in/7.8 out. I panicked a bit and did two gallon flush with pH'd water with the appropriate amount of Nutrients, but could not get my runoff to come significantly down so I left the plants for two days since they look very healthy. I left my plant for two days from the 11th-12th and came back on the 13th to see a bunch of new growth, particularly in the new nodes. I used LST to gently bend the main stem to the side and tuck the big fan leaves blocking light from the lower growth. I also increased the lighting intensity by switching my dimmer up to 50% power, but after a few hours I noticed some slight bleaching on the tips of the new growth that was now exposed. I raised the light enough to bring the DLI back down to 28. For watering, I've been mixing 1 gallon at a time right before feeding and running that through the 5 gal pot, which seems to give me the appropriate amount of runoff. I water about every 3 days, but base it mostly off the dryness of the top layer of soil. Early on I saw some fungus gnats or something similar so I made a note to let the topsoil dry out in between waterings.

infamousdro Watered 1 Gal of GH Bloom Trio 1tsp of each for "Bloom Transition" on the chart(followed at 1/2 strength). I've been pulling down the main stem every few days to keep the canopy even and promote side branch growth. Today I added another coated wire to pull it down a bit more. Plant looks very healthy and is definitely starting to grow a lot faster. I saw the first few pistils a few days ago on some nodes, and now they are starting to show in a few places over the plant. Some branches are starting to stagger, some are still perpendicular. I defoliated two small leaves under the canopy that were laying in the dirt and making it more difficult to water. From here I'm going to continue with the 1tsp/each of Bloom Trio until budsites start forming, and just continue to train branches and tucked leaves while it stretches upwards. My PPFD is measuring around 500, plus or minus a few around the canopy. DLI of about 38. XS1500 is dimmed to 60%. I stopped caring about the pH of my runoff since my soil is a CoCo mix and that seems to be the consensus. PPM of nutrients going in was about 750, I measured about 1100 in my runoff which seems okay to me. 4/26 Watered about 2 gallons through the pot with 1tsp each of Bloom Trio. Defoliated some lower fan leaves and continuing to train her outward to fill the tent.

infamousdro She has officially entered her stretching phase. I count 20+ bud sites at about canopy level and am continuing to train the tall branches outwards. It has been an explosion of growth and I have the beginnings of a time-lapse to prove it. I water with at least 2 gallons every feed now to make sure she gets a good washout of any accumulating nutrients. Last time I measured runoff pH it was still in the 7.6 range. I feed from 6-6.3 pH to counter. I see a few leaves here and there that look like a slight growth deformation, or some kind of pest, but I have been unable to idenifty anything specific. Been doing my best with my ceramic heat bulb and humidifier to keep the tent dialed in at 85F and 65% or so humidity. PPFD is in 600 range with DLI around 45 across most of the canopy. Still running 20/4 light schedule.
