I'm having an issue with some seedlings and wondering if my LED might be the problem. At first I thought it was the nutes, ie over doing it, but it has happened again and this time they were still in starter cubes fed with dechlorinated tap water. I cant post photos at this time, but it looks like nutes burn with white spots. I first noticed browned tips on one NL seedlings when my DS200 was placed about 18 inches above the new sprouts. I backed the light off to about 36 after that but all but 2 out of 6 seedlings are showing the same sypmtoms. The first one is now pretty much done. Once I saw the others show signs I backed the light off another 12" or so. So I guess my question is this, has anyone seen burn from the DS series and what does it look like? I can relocate this to a separate thread, but wanted to put it out to our LED gurus first. I will try to get some photos up soon.
First off i`m the furthest thing there is from an LED guru. I`ve just completed my first indoor grow. I started off with 1 Advanced Diamond Series 300. Had 7 seedlings under it. When they started to get any size to them I realized the 1 LED wasn`t getting enough coverage. Had to dig real deep into my pockets and find the funds for another light. Ordered it,installed it and jumped back. These damn things are REALLY bright. after determining sex I ended up with 2 young ladies. Started off with the light 30"-32" above the ladies. After the second light was installed, gradually moved the lights down to 16"-18" above them. IMHO you gave your ladies nutes way too soon. My girls didn`t get any nutes until they had 4 or 5 sets of leaves, then only 1/4 strength. I harvested 5ozs from 1 and 6 ozs from #2 of dried and cured meds. I don`t think I will grow outside again. Especially after my investment in the LEDS. I did alot of research into the various companies and decided the Advanced LEDS were on the top of the heap. I definitely believe in LEDS.
