@chuckles, a soil grower here, if I were you on your second grow i'd try and keep it simple love. I'd add a little N (grow nute) and leave them be, 4 weeks in and they look like they're doing fine in my opinion there's no need to be adding stress or any possible recovery time as you could be as far as half way through flowering already (strain dependant), do as the lads said and remove any dead leaves you see, after you have a couple of grows under your belt you'll start seeing things that you would like to change and experiment with but for now I'd concentrate on the basics (environment, water-feed schedule and plant health) when you have these sorted and feel comfortable with the above the rest will fall into place and be worry free, after all if you manage the basics in soil you will end up with a great end product, I honestly believe growing in soil is so easy for the quality you get at the end especially if your using organic nutes, it's hard to rival the flavour and quality of the end product with very little work needing to be done to achieve easy results. rambling on now i'm a bit too stoned to have to be thinking aloud but the message should have come across as kiss (keep it simple stupid) and all will be good
