Day 35
Temp 83 RH 57
Wow!! Are we really on day 35!! I am pleased to report that I was able to recover from almost certain disaster. The grow, like the entire tent, started to crash right around day 18 or so. That was when I stopped posting. (Oh and about that, sorry, but I needed to stay away from the grow as much as I could. This was to reisit the urge to fiddle with things overmuch. Not posting about it helped a lot.) The leaves started going brown and getting crispy. If the grow crashed completely, it would be the second one!! Yow! Should not have been happening from over feed, over or under watering, the usual suspects. I believe it is one of or a combination of the LED panels I was using, they are too strong and I had them too close or there is something wrong with them. A new tent I purchased "outgassed" poisonous fumes, most likely phtalate from the film inside. China not having the best quality control. Could also be mold as I found some on the wall in a corner. Or whatever!!
So over the past few weeks I tried to find out what was going on and if I could remedy it. First I tried to seal the tent from the other suspect one. I had, had the two combined with 6 inch duct for venting and heating, I severed that connection and sealed them both as best I could and let everything be for a week. Things did not get much worse but no improvement. After that I took out the LED panels and replced with CFL, 8, 23 watt 5.5k after a week they started to look better so I added another 10 CFL a mix of 5.5k and 2.7k. I am pleased to report that things look pretty good now, they look like they are about two weeks behind in size but the four autos have started to flower already!
During this whole time I watered with RO pH'd to 6.2 with 9.8ML of CaMg+/gal and was careful to not over or under water.
If I get off work on time I'll try to get some good pictures tonight!
