Organic Double Grape Autoflower

First 7 gallon grow. Hoping to implement lessons learned from last grow, primarily: -Water with PH'd water once above soil -Don't underwater -Keep Temperatures warm enough overnight. Humidity dome used Added ring of rope for use with LST ties. Sharing grow tent with a flowering, stunted plant (I will prioritise this new grow) March 31 - Overnight temp dipped to 67F. Will need to adjust heater range. March 31 - Sprayed soil to ensure moisture APRIL 3 - DAY 1 - GERMINATED April 3 - Day 1 (Germinated in approx 4 days) April 3 - Will keep humidity dome on until sprout has opened slightly further Will assess light burn as lights are 26" from pot. April 3 - Sprayed soil with 6.3 PH water at Noon. April 3 - 5.15PM Sprayed soil, both cotyledons have unwrapped, and are now repositioning to light. April 3 - 5.40PM Worried lights are too strong. I have 2 TS600 (100w each) 26" above seedling. Cotyledons seem yellow, will monitor April 3 - 5.50PM Raised lights to 27" above seedling. April 3 -11.59PM Noticed yellowing of true leaves. Sprayed before lights off. Will only have 1 light from now on perhaps April 4 - 6.20AM Overnight temp 70F, misted soil, stem is now straight after darkness. Will monitor dis-colouration. Height approx 1 cm April 4 - 10.30 PPFD is 145 with 1 light, 350 with 2 lights. April 4 - 2PM Height already at approximately 3cm. Stem straightened April 4 - Using NEXSEL I converted LUX reading to full spectrum light and PPFD is likely closer to 172, not 145, Should still be okay as it's under 200. April 5 - 8.00AM Height at 4cm, not much growth since yesterday. Misted soil at 8.30AM April 5 - 2.00PM Soil is still moist from fallen condesation within humidity dome 2 days ago. Unsure if this is sufficient water for growing root system as growth seems to have halted. April 5 - 10.15PM No significant vertical growth, perhaps leaves elongated - misted lightly to avoid overwater but provide extra humidity to true leaves. April 6 - 7AM Soil moist, height unchanged, true leaves are widening to 1" diameter. April 6 - Replaced Air Filter dust cover April 6 - RH 60-75%. Temp 74-79F. I will water tomorrow, April 6 - 4.50PM Praying leaves, height seems unchanged. Soil starting to dry up. April 6 - 5.30PM Height 4.5cm April 7 - FIRST Water at 7.30AM Used turkey baster 2x with wide diameter to encourage root growth. April 7 - 5PM Approaching 6cm, growth has resumed. April 8 - 5.50AM Overnight temp of 68F (Potentially lower). Will assess growth rate. April 8 - 3.20PM Second set of True leaves developing, leaves widening. April 8 - 4.20PM Watered at circumference of pot approximately 100ml April 8 - 10PM Height approaching 6cm - leaf width 2" April 9 - 8.45AM Watered slightly more than yesterday. April 9 - 1.00PM Rotated pot 90 degrees. Moved slightly closer to light - Hoping to get mid 70F consistently this way. Will measure lux. April 9 - 5.45PM Perking up, added few drops of 6.3PH water at stem. Fan was oscilating nicely, swaying stem and strengthening in turn.
