Any advice?

Hi everyone. This is my first grow and was very impromptu. I sprouted some seeds that were over a year old, saved from several different strains. Just lucked out that they all sprouted and all ended up female. No idea what strains they are. I have 5 plants that all look different and are different sizes. As this is just fun for me, I kind of learned as I went. I have a 7×6×6.5 area. It seems not to be super popular but I'm using LED. Right now I have 5000 watts( I know that doesn't tell much but I don't have a lux meter). Started w 1 light and as they grew, I got more lights. I am just starting flowering week 4 and have used this site for much advice from all u fine enthusiasts. Have had no yellowing or health problems at all throughout the entire process. Have defoliated twice because of heat and bud coverage. Just looking for any advice or anything I can learn. Thanks!!!

Carry on looking good. I would say that's making some good use of the search function.

Those lights have the strangest spectrum

Leds are very popular by the way. Its getting better and better. There are some hate towards blurples but its mostly because the cheap knockoff fixtures were not able to deliver what they promised.

You are overfeeding a bit imo. The tips are brown and plant is very green. A little less nutrients would be better.

What is the true wattage of those lights? What do they draw from the wall i mean.

3 of them pull 200 and one pulls 392. During veg 1 of them got a bit of the claw so I stopped giving them nitrogen all together. Since switching to flower I've dug in .25 inch of jamaican bat guano, 0-5-0, into the soil and give them a general feeding of tiger bloom every other feeding. I honestly tied them down because I thought the tips were browning because they were too close to the light as this is a development over the last 2 weeks. If it was due to the light would I see bleaching as opposed to browning tips? I've read that light damage takes a while to show up and I have seen no bleaching. Thank u so much for both of your replies!

So 1000w of true draw. How high from the tips?

By the way, i don’t see light burn and light burn doesn’t manifest itself with brown tips, thats over fertilization. Maybe drop the tiger bloom to once every week or 2 weeks. Really they look well fed.

Had them @8 inches but now I have them about 16. Will absolutely drop the tiger bloom down. Did some cropping after week 1of flower and all 8 rooted nicely. Going to try some LST with those. I tried topping one of these but I just tied the rest of them down by the tops because I'm honestly just trying to learn how they grow... fast and tall... very fast and tall.
