Day 21 Update

Not too much to report really but I wanted to check in and show you guys how things are looking. The Tahoe OG's all got really burned and I'm not really sure why. They do happen to be the ones under the LED but I don't really think that's it. The burning happened after I did the first feeding...but I only fed at 110 PPM's. Maybe they are really sensitive to food??

Well...at any rate, all of their roots are doing great. Nice and healthy white so I'll just keep nursing them along for a little while..not too worried.

Lights have been on 24 hours a day since the start...it is kind of required with my ambient basement temps being at 48 degrees. To my surprise, I have not had to heat my rez. The water is coming out at 50 degrees F and within a few of hours it's at 69. Not using the chiller yet but I will have to sooner than expected.

15 minutes of extra light won't make any difference. Some plants just take a lot longer than others. Sativas take the longest, and the blue dream is the most sativa or your strains, so it should take the longest all else being equal.

Effectively is my first time with a sativa dom. , BD is 70/30 I used to grow mostly indica strains.. i believed flowering was longer but starting at the same time. She will need more than 10 weeks to harvest, mid august i think. Thank you.

I cropped most of lower branches and leaves, or I had a real jungle. I read 12/12 should give mostly a single big cola, but all plants developed significant branches. The tallest, a blueberry headband is about... 12" already with 4 lower branches I'm not able to cut .. other 2 same strain are much smaller, not more than 6", same pot, same light, same watering, cant understand why.
The growroom is in an under roof attic. Theoretically they will be ready between 20 july and 10 august, I am afraid it will be too hot. Here in summer temps will be about 28/32 celsius during daytime... light are on from midnight to 12, leds dont heat too much, but im worrying about daytime temps. Cant buy any cooler... im unemployed now.. more vents would work for it?
