LSD Auto LED grow

Here we go... week 2! Everything went pretty smoothly during germination and week 1. I'm starting to think about nutrients, as i do plan to start feeding, VERY lightly, sometime this coming week. I figure my soil should probably be okay for 3-4 weeks but i'm going to be feeding only 2 of the 3 plants starting in week 2. I'll start feeding the 3rd plant in week 3. I want to see if there's any difference or problems that arise. Day 8: - Temp: 74-80F - RH: 68-71% - no water, reduced exhaust fan speed to 10% at night due to colder outdoor temperature. Day 9: - Temp: 72F-79F - RH: 62-69% - lightly watered with de-chlorinated tap water Day 10: I've now desgnated the plants as "L-1", "L-2" and "L-3", based on their germination and seedling stage growth, with "L-1" being the most vigorous. - Temp: 72-76F - RH: 65-68% - Lightly watered "L-2" and "L-3" with a very weak nutrient mixture using Remo Nutrients' "Micro", "Grow", "Velokelp" and "MagNifiCal". Remo's feeding chart recommends 6ml/gal for week 2. I used .5ml/.5gal... 1/6th the recommended dose. - "L-1" was watered with just dechlorinated tap water. - Both adjusted to pH6.5 Day 11: - Temp: 69-76F - RH: 62-68% - No water - added sticky traps for fungus gnats, which have afflicted one of my girlfriend's orchids in our house. We've quarantined the orchid and will be giving our houseplants a few doses of BTI. Crossing my fingers that they don't cause me any issues in the tent! Day 12: - no signs of fungus gnats in tent - Temp: 69-77F - RH: 62-68% - No water Day 13: - no signs of fungus gnats in tent - turned humidifier off - ambient RH is about 60% - Temp: 69-77F - noticing leaf edges curling. Possibly due to high RH and/or over-watering. - Calibrated pH meter. Was off by +0.3 pH. - Watered lightly with pH adjusted tap water @ 6.4pH Day 14: - No water - Replaced the 24" Sunblaster T5HO fixture with a 24" Sunblaster LED, which now makes two of them. I plan on switching the 6400K T5 bulb with a 2700K bulb in the T5HO fixture. Once flowering starts, I'll pull out the two 6400K LED fixtures and put in the 2700K T5 fixtures (I still need to pick up one more T5 fixture so that i have two, which i'll be placing at either end of my 2x4 tent as supplemental lighting). - Distance to canopy (24w Sunblaster LED): 12" - Distance to canopy (HLG Elite 360): 24" - Elite 360 Light Intensity: 35%
