This is my first grow and unfortunately my lady suffered a big stress because I didnt realise early enough that she had a PH lockout. It was a 5.2 PH run-off 4 weeks into it and I realised after 1 week of browning leaves. As soon as I realised the PH lockout I flushed her, leaving her with a 6.5 PH run-off but she suffered a big stress. The thing is that I gave nutrients for the first time as soon as I flushed her and that might caused a problem? Some background info: Strain: Lowryder #2 20/4 light cycle 200W CFL 5 weeks old in a PC box using soil Counting 5 days after the flush now The top leaves are not looking good at all (having suffered the flush and everything) but the new leaves coming out and the bottom ones seem very healthy. Should I cut off the sick leaves? And what I am worried about is the top bud (the rest of the buds are fine), its almost completely brown and dried what should I do?
