I can't elaborate on your nutrients; I don't have any experience with them. However, as noted, perhaps your ratios were off? I would sit down and get this sorted out before going too far, and being you're in coco, I would be at a minimum checking your pH (5.8 ideally) and if you can monitor your EC / PPM, that would be even better.
You mentioned you just transplanted them a week ago and I can see you're into LST as well...you have to realize the plant is stressed from both at this point, so you have to be a little patient with her until she acclimates. With that being said, when you transplanted did you wash / rinse any newly added coco and did you buffer it out prior to using it? This alone can cause issues if you haven't done both.
Just a few pointers from my own experience. Don't let your coco dry out...your plants will experience burn from doing this. This is why matching your plant to the pot in this type of grow is important. It's not necessary to have a giant pot. In fact in your size tent I wouldn't go over a 2 gallon pot and that is probably too big. A smaller pot will allow you to feed more and you'll find that 'over watering' as many like to call it, will not be your issue. Also, don't water with straight / empty water...ever. If you feel the need to give them a break from nutrients or if you feel like you must do a 'flush', do it with a reduced feed %, like 25%, but don't use just water...this will goof your plants up as well.
So, if it were me, I would get a handle on your feed. Once you know this variable, make yourself a 50% feed solution and fully saturate your plant, to the point of copious runoff, drain the runoff and leave her be. If you had too many nutrients in the medium, you'll flush them out with this method and in the process you're re-setting your medium with a reasonable feed value and the proper pH value. Then feed according to how much she's 'eating'. To start you may be able to get by with feeding only once a day or two, especially if you just transplanted into bigger pots. As your plant begins to fill that pot with roots, and as the plant grows, it will begin to use more feed and you'll be able to get to the point of multiple feedings per day, every day, which is the true advantage of coco to begin with. Ah and one last observation, be careful with the 35º C maximum temp...that's a smidge warm. If you can't do much about it, for sure keep your RH up. Hope some of this helps...good luck.
