Hi guys, I really need some help with this.

First, There are a lot of rust spots which looks like it's too late to really do anything about but i'm open to suggestions. I thought it was calcium deficiency at first but now it seems more likely I nute burned the s**t out of them.

My second issue is that I have 2 different strains going (1 white widow, 3 ice) and it appears the white widow is going to finish up much quicker. Should I stop all nutrients now? How soon should I start flushing them?

I appreciate any help... It's obvious I let this garden get completely out of hand but I'm hoping to still salvage it the best I can

The last photo is of the white widow (no rust spots) which looks pretty close to being ready

Thanks!

Bump for you. Sorry, I can't really answer your questions very well as I'm not a hydro grower.

Cut out the seaplex, you won't need that anymore.

Also, you can cut back on the Cal-Mag plus, 8ml per gallon is about .8ec of Cal-Mag... kind of a lot, so I don't know if you had a calcium shortage as much as a pH fluctuation at some point because you definitely had enough calcium in there between the CNS 17 and the Cal-Mag Plus.

You can push the sweet maybe 1 or 2 more times before you'll probably want to cut back on that a little too.

Also, you're pushing a hell of a lot of phosphorus with the 20ml of the 1-5-4 ripe with 3.5 ml of the 0-10-6 hydroplex. At this point (maybe 10 days to harvest) you definitely don't need to be pushing the Hydroplex anymore.

The CNS 17 Ripe and the Sweet should be all you need from here on out.

Flushing in the Ebb/Flow should be easy and quick. You can probably flush them down in 2 days pretty well. I'd follow the instructions on the Ripe and the Sweet bottle labels until I was about 5 days from harvest. Then I'd start flushing and watch those trichomes.

Looking good dude.

Thanks Snow Crash! I changed out the reservoir only going with the Sweet and CNS 17 Ripe. I appreciate your time and detailed response.
