lowering overall yield in veg

yeah but if you cut them back with dirty scissors you can get root infections and root management is not easy thing to do once one has an infection you have to pul it out right away.

I am finishing up my first grow and I burned my girl with too much liquid cool bloom. From the time I noticed the initial nute burn I had given the same amount again in a separate feeding three days later( this is the very reason I believe people say water feed water feed etc.)The bud size from that point did not fatten up like it should have and as I sit a few days or so from harvest they have not gained much size since. It still has nice buds and trichome production is great but just not huge like they should have been. Take it from a newb who did it. Don't overfeed your plants. Here is a pic of them at day 55 of flower for reference ( wonder woman by nirvana)

The only way to know for sure is to take 2 clones from the same mother.

Stress one out and keep the other healthy then weigh out the final product and see.
