Need advice with late flowering

I started my first hydro grow in early June. I have 2 weeks of flowering left and I ran into a problem.

This has definitely been a learning experience, and I know I made a few mistakes:

First mistake: I vegged the plants too long. I have pretty much no room left in my grow tent, and I've had to tie the branches down so they don't hit the light. Because of this, not much light isn't getting to the tied down portions.

Second mistake: I'm growing different strains in the same system (ebb and flow). To top it off, I'm growing 1 sativa (purple haze) and 4 indicas (3 white widows and 1 kandy kush). Next round of growing I will stick with 1 strain.

My problem is that the white widows (they look sexy!) are going to be done before the kush and the haze. The widows have nice buds and are very crystally, but the kush and haze are not nearly as far along. I'll need to flush with straight water for the last week for the widows. But I'll have to let the kush and haze flower longer.

After I harvest the widows in 2 weeks, I'll still need to keep the kush and the haze flowering. Will it be ok to add nutrients for another week or 2 then follow that up with another week of just water? Should I continue to use water for the final weeks of flowering the kush and haze? The haze and kush are on 1 trough while the white widows are all in the same (separate) trough, so pulling them out won't screw with the roots of the other 2 plants.

If I'm kinda screwed at this point, then fine, I'll know better next time, but I would like to salvage what I can if possible.

Thanks!

Your widow will be done before a kush? are you sure? Best advice i can think of would be decide which kind you like the best and work one flush for it and just deal wth the others less flushed. My opinion isnt popular but i dont even see much reason to flush anyway A proper dry will make it taste great no matter what.

You can just lower the EC a bit. A lot of commercial hydro guys dont "flush". Example, HR just runs low EC (1.2-1.4?) the whole way through. A proper dry/cure should make more difference than the flush.

I think a lot of people learn that lesson their first couple of grows. Having a lot of strains is cool, but unless you can deal with canopy management, it's a real pain. Consider vertical lighting!

Cool. Thanks.

So basically I should kick the nutrient levels down and just skip the flush all together?

Yep. Positive. The Kush is dominating the rest of plants in size. I topped it twice and it has 4 huge tops, but they aren't budding like the WWs are. The Kush has white hairs, but not any noticeable crystals yet, whereas the WWs are loaded with crystals.

I did read somewhere that Kandy Kush does take longer to flower compared to other strains....too bad I didn't read that sooner.
