First Grow - LSD DWC

This was a good week. The girls made progress with correcting my nutrient burn error. The nutrient burn isn't any worse. As a newbie, it's my understanding that it won't heal and go away. However, all new growth looks good to me. My Mars TSL2000 lights came in and I'm very impressed thus far. They put out significantly higher PAR than the old light and cover a much, much wider area with it. I bought two to cover my 4'x4' tent, but since I only have three plants in there now, the one light easily covers it. It doesn't get very hot either. I couldn't be happier with them thus far. In the next couple days, I think I'll try topping the plants. I may top all three or maybe just the one that didn't show any signs of nutrient burn to be on the safer side, not sure yet. I'm also considering trying to clone these tops that I trim off. I know it's not ideal, but I've read of it being done successfully. After all, what do I have to lose other than a small dab of Clonex? If that experiment actually works, my next decision will be should I go ahead and veg them with these other plants that are 3 weeks further along since I don't have a good space for more full size plants? Since these are photoperiod and I have plenty of room I don't see that it will hurt to have some extra plants in there even if I flower them early and don't get much out of them, but that's a decision for well down the road if it comes to that. I'm pretty happy with how my first grow is going. I'm learning and that's the most important part after all.
