Topped Right after preflower

So I've read quite a few threads talking about whether or not topping during flower or preflower is beneficial or not. Well I decided to test this theory. I have a cloned Hybrid Blue Magoo crossed with an home made strain called Home Depot. Vegged for 2 months and has been flowering for under 1 month. So I decided to top a quarter of the main branches to see if it would make any difference.... And as you can see the ones I topped have 2 main budding spots at the top verses the single ones. There's even one that I pitched off the top but left about half un-pitched and there is 3 bud sights at the top. I'm really excited to see how she turns out. She's a giant taking up the whole grow area in a 3ft by 3ft by 6 ft tent. Also to solve another question as to which fertilizer to use. I honestly jungle between a mixture of probably 15 to 20 mixtures of FF Dynagrow and maxigro Schultz advanced formula RAW !!! As long as my PPMs are close to what each stage of growth calls for your good. Find what your plant can take and give it that. Also in DWC ROOTS WILL TURN BROWNISH IF YOU USE DARK NUTES
