Leafs showing burning

Hi there, I guess the biggest question is what have you changed recently since you have noticed this? Looking at your list of nutrients I would say that it seems to be a lot for this stage in the game. If you look at my diary my critical purple autos have grown aggressively and I have only fed them low dose veg nutes and now coupled with some lower dose bloom nutes. Obviously at this point I have upped my nutes as I am closing on week 7 here. I would ramp back the nutes and maybe try a straight PH 7.0 balanced flush on your next watering to make sure you aren’t too acidic and clean some of that crap out of there. The other thing is that when you are feeding you NEED at least 20% run off so that the nutes don’t build up in the medium. Also, when you do reintroduce nutes on your watering after that maybe try about half what you are giving them and slowly increase. The other question I have is why are you giving cal mag? Is there a reason for it or are you just doing it because you think you should? Don’t just give them whatever it says on the bottle. That’s what you need to work your way up to. Don’t complicate it with many things if it’s not required! I’m not even at full strength for going on week 8 and I’ve had zero issues what so ever. I hope this helps, and good luck with her.
