All looks good, I think its last two weeks for plants, bi started to flush them, and I also put more light for last two weeks maybe more, we will se soon. Trichomes already looks milky.
DWC is slow to take off. If you look at my coco, she has started her own DWC and ever since she started drinking from the plate she has exploded this week. I'd chill on the LST. DWC does much better when more or left to it's natural state, it just looks like your going to heavy with the LST on the DWC. Have a look at other DWC,s they blow coco out of the water, pun intended lol. She'll start to explode soon, as it's DWC you should have some sort of root stimulator nute, it's more or less vital with DWC. It's all about getting that bucket heavy with roots, root growth is Like a mirror to top side growth if you get me, same way if you plant in a small pot roots that have as much space to grow, (meaning top won't grow as big, that's why ppl transplant), but all the space in the world is no good if you aren't taking full advantage. Looking at your roots on week 6, there really should be a lot more pal. It's not bad, and most importantly, they look very healthy, if you were to take your coco roots out now there would be way more growth. As it has a structure to grow through when doing DWC that isn't there so you have to add a root stim to compensate. That's my understanding, you are still in the very early stages and this can be fixed. I'd pull every Lst You have on it and start letting it grow up. Get a root stim 10-20$ for a decent one. Biocanna or Advanced Nutrients are very good. Well they have been for me. Good luck. As for if yoi are using to many nutes that doesn't matter, I am using a total of 14 different bottles, once you keep the PPM in DWC for early stages 1-4weeks 500-800 5-7 800-900 8 to flush 900-1400 that number is very high, but keep pushing your plants and watch for early signs and adjust, just be sure not to use too much of the same nute to reach that PPM number. If you are increasing always making a mix of each nute and as you know micro is key, so I'd give 1/3 extra on that doing DWC so you avoid nute lock out and increase nute uptake. Hope this helps. Good luck.
@Fast_Buds, doing my best, photos could be better quality, but I'm not professional photographer, and don't have eq. But, most enjoyable is how plants develop in real life. Thanks 420buds fo everything. :)
