Looks like a claw

looks like a plant wilting form lack of water... the whole thing is doubling-over. the plants aren't overly lush, otherwise. if somethign is out of whack, it's not far. Water that girl more often. what are your irrigation habits? these are often wrong in new growers. i see you are in soil -- so make sure entire thing gets wet... a little runoff is okay and ensures of this, but is not 100% necessary and does leech out some nutes from soil, so less runoff is better for costs over time, but amount to pennies and well-worth the cost to err on this side of things. after that you wait for top 1" to dry and repeat. If the weight of pot is same at each point you irrigate, it'll require teh same volume - if concerned about planning and waste of fertlizer mixed (your time or cost)... This is the proper way to learn how much water you need per irrigation... in hindsight and consistently watering at same loss of weight from pot - water drunk+transpired or evaporated = weight loss. so you fully saturate... allow enough use of water before irrigating again... waiting for top 1" is best early on and for reduced risk of issues with substrate. Doing this will train the roots to drive deep for water instead of toward surface, which is the problem with not saturating entire volume of soil among other things (dry pockets can cause conentration and pH swings over time, e.g.). if you want to water/fertigate a bit more frequently later, that's fine... in a pot that stays wet for 4-5+ days, probably not wise. (small plant, big pot context, for example) if more frequent, be sure to drop concentration with that increased frequency. relative to local variables, the plant can only use so much per day or per week... increased frequenc just keeps it at a more optimal level for longer periods of time = lil faster growth.

I noticed the only thing your diary doesn't tell us is how much they're drinking every twenty four hours and for week two it might just be to much feed for that pheno so she's clawing. When you I over feed, depending on how much and what nutrient is in excess, is going to determine what symptoms your plants show. Regardless you're only using a two part system so it's simple. Lower them both. Maybe just back off on the feed a bit and see if that helps. Hope this helps.
