Sometimes wind burn dries out the leaves, but doubtful that's the case. My plants can almost take a tornado without flinching.
Overwatering, and you'll suffocate the roots, and usually comes with sagging 'puffy' leaves, eventual yellowing, then greyish blotches on the leaves as they die. Eventual root rot is almost the final nail in the coffin.
Underwatering, and the leaves generally brown-up and die fairly quickly. But they do sag like yours a tad if left unwatered. Did you break anything or let the roots dry-out when transplanting? <doh>
On your nexst watering day I'd flush with a dose of 7.0 ph water. See if it helps. 7.0 is close enough to being within ph range, and perhaps the buffers will struggle to keep the ph artificially low. However, ph will dive over time anyway, as the ph buffers fade. The buffers kick the ph up to compensate for the 4.5 ph of peat moss. Topsoils, mulches, composts have less buffers, which keeps the ph too low for cannabis.
Which is why I'd also get to the soil store and look for something more suitable for cannabis, and transplant asap. Make sure there's buffers, perlite, and that it's an indoor potting mix. Makes your job easier. (mine too, come to think of it. :thumbsup:)
It might get to the point of having to trim dying stuff off to allow that energy to go the potential healthy growth, but do not do it yet. Let's see if another week or so of patience and TLC helps. ;)
