Staggered harvest tips needed

I'm nearly ready to harvest my girls but I have a lot of undergrowth that is premature and not ready. Once iv completed my flush I was going to chop what is ready and then continue with the feed I was running prior to flushing. Has anybody had experience doing this before? How much shock will cutting the main colas cause and roughly how long would I need to hit them with nutes again? Any advice and tips would be much appreciated. I'm growing white lemon in hydro pepples btw ��

Ok, so here it is. While doing so will not shock your plant to bad. You would probably be looking at an additional 2-3 more weeks to ripen the popcorn buds. Soooo maybe another week and a half or so of nutes. BUT to be honest, It really is NOT worth doing. It wont really plump them up, and the additional weight is minimal. If you have more girls in veg, on deck, ready to flower, you are better off to just harvest the whole plant and put the next girls in.

I agree with amgrpb. Buds that ripen evenly are a good trait to look for in ganja genetics.
