Restart run

22/02 start of week 4 The 3 girls are growing pretty well,2 are about 15cm tall now and the short one is like 12cm,the small bulky one I topped at day 10 and again yesterday day 21,I wonder if it’s because I topped her so early that she is so bulky,first 10day’s she looked like her sisters who were topped on day 17, they seem to keep growing bigger internodes I pinched these girls stems yesterday and today they were almost completely hard again,does anyone else uses this technique btw? Let me kno 24/2 all 3 girls got a feed with ec 1.7 ph 5.5 Run off was equal on all 3 plants ec 2.1 ph 5.7 Ec went up a bit high butt not a point that I’m worried because ph seems to stay stable 25/2 topped the 2 biggest girls for the second time,all are looking pretty happy 28/2 accidentally broke 1 of 2 main stems whilst trying to tie them down but maybe I pushed it a little to far this time 😅
