There we go! They are looking much happier and healthier now. Are you gonna take any clones of them before you flower so you will have a new batch to work with after you harvest these girls?
I love your nutrient choice, smart smart man going with the beneficials, you can give them credit for your nice recovery, way to go, Mycorrhizal fungi can take months to give you the full benefit, I would even out the canopy by taking the tops off and cloning them, so you have some moms for the next run, and you can also pick the best smoke and keep that mom and ditch the rest in favour of another strain.
Main thing no is to top and train, look around on 420 there are lots of how to threads on the subject.
Think about flowering nutrients as well, they should be lower in Nitrogen, but I am sure the line of nutes you have now has a flowering solution for you.
Also if you do not have an extraction fan get one you will need to prepare for some serious heat issues with your LED setup.
Things seem to be coming along nicely. Keep up the good work!
If you have a 6 ft. max ceiling, I would say start the flowering cycle when the largest one is around 2~2.5 ft. tall. That way, even if it doubles in size, you won't have your colas touching the lights.
Does that 6 ft. ceiling take into consideration the hanging light? If not, you may want to flower sooner than later, especially if you're not training the ladies down and out.
Do you plan on doing any topping or other cutting techniques? If so, that action will generate clone material. I never cut specifically to take clones.... I cut for other reasons and use the cuttings as clones.
I usually wait till I can take a clone with a minimum 2 nodes, I find I get better results that way, not any faster rooting but they do explode with growth compared to smaller clones after they root.
I usually cut growth off the 2nd node site, cover that area with rooting goo and plant it below the soil level. The cleaned node set is supposed to be another very active rooting area. That's the idea at least.
I can sure see how 2 or 3 leaf sets could help out once the roots get going. I may start taking longer clones.
If you top at 5 nodes just wait for 8, and do like you said, I recently topped some deep Chunkolate the one stem was 3/8" across, likely the biggest clone I took on purpose LOL.
This one was deep chunk dominant with massive fan leaves, I saved a fan leaf that wouldn't even fit in a 8" x 11" book had to scrunch the leaflets together and the whole plant was still only 18" tall, I am super impressed with Cannacopia's genetics so far
