Is anyone else flowering under LEC315W? I needed an energy efficient light source, low heat production, and broad light spectrum. Found all of that in these phenominal lights. Pricey however as i hace $1200 in 3 badboys. Worth it i think. Ive never grown before, but my girls seem on Par from everything ive researched. Day 28 currently with a 4 week veg.

These are under a LEC 315 and seem to love it!! Also with the 3000k bulb.

Very nice! What strain? How tall are they? What size pots? How many days into flowering? Topped or fim'd? How many lights and plants? Co2? Sealed room? Sorry for all the ???'s just wanna compare stats a little.
 
Thats like 1,5 grams per watt..!! That's outstanding, you got a remarkable grow going here VividImage :)
 
These are Afghan and a bluedream in the back they are in 5 gal pots and are about 30" tall but haven't measured them. Growing in a tent you have to kind of keep your plants from getting too tall. They are almost done. 12 weeks in flowering. And close but no cigar. The trichomes are white but as of yet no ambers, I would like to see a few ambers before I chop!
 
Daily pics Day 46, Day 16. Pretty sure i have a potassium deficiency, gave them pk boost last 2 feedings. Still seems to be getting worse, although im sure some is wind and light burn too. Some yellowing is attributed to them finishing too. I think haha.

Overall your leaves are mostly green, which is great. Have you been checking the pH? Do you have something that will give them a full feeding of all the nutrients in the right ratios for Bloom (as opposed to just a PK booster)? It can't hurt to make sure they have the right ratio of everything, just in case there's a micronutrient that they're missing. It could also be a symptom of a little wind or light burn, like you said.

The buds look chunky already, and I think they're still going to put on a lot of weight!
 
When I retooled I decided to go with adjustable ballasts from 600 to 1200 W and supplemental LEDs make sure keeps the temperature down
 
They got fed correct ratio of nutes, bud xl, drip clean, and molasses. Then next feeding same ratios, but added in pk booster, kinda gave em full strength instead of half, next day or so started seeing symptoms in leaves of what seemed to be mag def. So next feeding added in a cal-mag, hasnt made a difference. Maybe mag is locked out due to excess pk? Not sure so since its day 47 going to flush with ph water 20 gal per plant, check leach for ph and ppm then when flushed check em in a couple days. Keep checkin the trics and pray for the best.
 
Flushing already? Just curious, how long do you plan to flush for? They look like they still have at least a few weeks left before they're ready to harvest since most of the pistils are still white and sticking out. I only say anything because it really hurts your yields and potency when you harvest early. Your buds look so good you don't want to prevent them from reaching their full potential!
 
Im just flushing to correct ph and ppm then after a couple days go half strength on nutes and doubke check ppm. I will do a 10 day flush when theyre ready in a couple weeks or so
