Nice job, they will be fine. If you are concerned, you could always top your pots up with more soil so that it buries a portion of the stems, thus providing a bit more support. Over time your plant will send out roots from the buried portion of stem. Try not to have your fan blowing directly on your seedlings at this age/size, far better to have the fan blowing against a wall at 45-60 upward degree angle, so that the air goes around in a circle - off one wall, off the roof, off the opposite wall then back down to your babies. This will create good air CIRCulation without buffeting your fragile seedlings. You could just leave them too, either way they will grow normally. Hope this helps.... Organoman.

Don’t just cut leaves for the sake of it. You should only be cutting a leave for a reason. Every leave brings energy to the plant and if you’re going to just cut leaves for no reason you’re gonna damage your plant, research it first properly

Seems like a light Potassium (K) and Phosphorous (P) deficiencies - yellowing from bottom to the top, chlorosis, and blotching on a flowering plant. Try increasing your "TerraBloom" to about 3.5-4.5ml/l (start with 3.5 and slowly increase to 4.5 if gets better). The PK consumption of the plant increases immensely during flowering!! Hope this helps! Good luck and happy growing :)

You want the Runoff pH to be as close as possible to the feed pH but it is normal to expect a small rise due to buildup in between feeds. Just like with EC. Your runoff pH is a bit high so go with lower pH in your feed solution for the next few feeds and if you are really worried you can lower the nutrient dosages but try not to decrease feed solution EC too much in one day. A good general rule of thumb is to not exceed a change of +/- 0.2-0.3 EC from feed to feed.
