Nute burn with 3 weeks to go - to flush or not to flush?

Ok guys so it looks like I have nute burn on what was my most healthy plant, the pic shows the discoloured leaves and the dark spots scattered around with this happening on most of the top 1/3 of leaves.

The problem is I am 6 weeks into flowering with 3 weeks to go, this lady in question (Chrystal) 3 weeks ago had been getting yellow leaves on the bottom 1/4 and a grower I know said the plant was eating itself and needed more nutes. At the moment I am feeding her - 4ml BioGrow, 4ml (going up to 5ml next watering) BioBloom, 2ml TopMax (going up to 4ml next watering) and 1ml of Overdrive (going up to 1.5-2ml next watering).

If I flush her I am not going to be able to feed her this strength for a while I have been told as it will be like starting from seedling again in terms of using 1/4 - 1/2 strength nutes to begin with? All of the figures above are recommended on the BioBizz grow guide so I'm not overdoing it?!
I am worried that flushing her will mean she is without the vital nutes she needs in flowering at this critical stage and will effect the overall quality of the bud so can you guys point me in the right direction in terms of what to do..

i would flush

i would flush when theres 2 weeks to go

I also noticed that she hasn't been drinking as much when she is watered, before it was every 3 days and now its up to a week! I have only just built my ladies up ready to take full bloom nutes and was planning on flushing half way through week 9 (BioBizz grow guide suggest flushing half way through their last week) which means I still have 2.5 weeks to give them full bloom nutes.. This is a tricky one?!

just flush them and go back to your normal schedule, whoever told you that you had to begin again was mistaken, the plant is already established and has developed fully, you wont harm her. imagine gettin drunk and then the following weekend you only drink water, on the weekend after that you dont need drink half pints of lager because your body is fully developed and used to it.

Only thing is when flushing her I will have to wait up to a week before I can start feeding again.. Hopefully worth it as carrying on feeding her will only mean she isn't taking up her nutrients.

wait.. why do you have to wait up to a week? just feed her again once shes dry and thirsty..

It will be roughly a week before the soil has gone dry and is ready to be watered?

Also is there an amount of water to flush her with or is it just until it runs clear from the pot?

Flush with at least 2-4 times your normal amount of water..

Sorry just amazed your soil takes so long to dry.. my happy frog only mix takes forever and even thats only like 4 days 0.0

I normally give them 3 litres which is enough for them to drain so flushed them with about 9 litres. Every 3 days they would need watering (I write everything on a calender) but recently have been taking 5 days hence why I said it would take up to a week until their next feed.

Hopefully flushing them has opened up the roots again so they will be drinking faster?

Also will the spots on the leaves disappear now she has been flushed?

when you flush, flush with at least 3X the size of your pot in water (I.E. if your using a 5 gallon pot, flush with 15 gallons of water) and then let her go until shes dry again. after, you can rewater with 1/4 strength fertilizer and see how she does. dont go any higer in concentration until shes showing much improvment. generally no, the spots that are already there are there, cause their dead. if the leafs over 50% damaged, clip it off. i very rarely have any issues wit any sort of nute burn, but what i do usually is after i flush, i clip off all damaged leaves and let her put new ones out. doesnt hurt a thing unless you remove more that 1/4 of the plants veg or more.

When I had burn, I flushed and waited 5-6 days before resuming feeding. The leaves that show burn don't repair themselves, but after the flush I waited almost a week just to be sure there was no more sign of burns on unaffected leaves. Then I lessened the ampount I was giving them of ferts
