can i go back to nuts after using shooting powder and flushing

So i this this is my 1st grow and i am running with the full House & Garden nuts. I followed the 6 week flower chart not thinking that the strain i am growing takes atleast 8 to 9 wks. anyways iv been flushing with R/o water for the past week and 1/2. Im now realizing they arn't fully mature and need at least 3 mor weeks. So my question: Is it ok to go back to nutes (H&G aqua flakes A-B, and Bud XL) even if i used the shooting powder already?

Any pointers would be awsome , Thanks

here is some pictures

what week do u want to go back too. what r u growin in. i have alot of tips with that line. one is on week 5 i do one more wattering with the top booster than the chart says too. huge difference. let me know what your systems like and ill share more.

Im using a DWC system , like a rubbermade 30 g container with 5"air stones. i did go back to week 5 of the non agressive growth but without the top booster.

what i do if my buds dont look like there on schedule and your on an 8 week flower cycle is continue the last week till their ready. 2 day flush when ready then dark period for 24 hours. so theres really no difference. just the amount of shooting powder. id say grow them out.

so continue with the 2 bags of 1/25 g shooting powder with the same nuts as week 8?

when week 8 is done and your not satisfied do another week 8. im sure u keep up on all your magic greening right. your plants look great if your on week 6 then they have only been in flower 5 weeks. your good bro. how do u like your DWC system. ive got a great soilless way thats pretty dam awsome.

i like the set up but it had one flaw. i had an issue with my sativas overwelming my indica strains dealing with growth . so i wasnt able to move the plants around at all because the 6 net pots all shared the lid.

im going to look into a different design on my next run for sure

so i went back to week 6 of the house and garden 6wk flower chart yesterday. i checked on my girls this morning and some if not all the leafs are looking a bit burnt. does this have to do with the shock of going from nuts to a wk of flush then back to nuts?
anyways ill post up pictures of the girls later today.
anypointers out there?

the only Nut I NERFED when repeating week 6 was only half the amount of shooting powder to decrease the chance of nutrient burn
