Grow #1 - 75watt LED CMOG bagseed

All photos from very end of week 4, I'm going to try to keep this schedule to see progress more easily. Previous week photos are from 4 days ago rather than 7. I noticed burnt tips on the cutting, I think from nutrient burn (versus K+ deficiency). I cut back the dosage. I realized I've been winging it in terms of nute schedule. I began adding just 0.5ml of Micro and Grow this week as I realized some of the micronutrients like Mg, Ca and Zn aren't in the Bloom. I did a couple days of water-only after I suspected the burn. Two colas are 4-5 inches from the QB at this point. I tied them down very loosely to the tent poles so that they lean slightly away. I think the low wattage of the QB allows me to go a lot closer than the recc'd 12-16inches. I don't see any burnt pistils or leaves on those two. I also increased airflow between the colas. I usually had the fan pointed towards the tent walls to avoid wind burn. I think my stems would have been thicker if I had more movement from the beginning. I have an oscillating clip fan arriving soon that will replace the floor fan. I continue to run the inline fan (w/ carbon filter) at the top of the tent 24/7 to draw out heat. The tent is open most of the time during the day too, with a fan in the room.
