Wilting, wilted, toast

[billybobgrower]

Howdy folks,
Long time hydro grower but I'm damn near ready to throw in the towel.

Little history here! Moved to a new town where it is well water, nothing but problems for the first year until we put in a Reverse Osmosis filter. Plants picked up tremendously and I thought Woo Hoo! good old days again. Then I used a new product Carboblast and put in based on 80 litres instead of the 70l in my rez. Jelly roots, barely saved the plants. Second room, 10 Bubblegum growing like the weeds they are. From 4" clones to 12"x12" bushes in 3 weeks. More Woo Hoo! certainly happy days again. NOT!
Within 2 days 5 of the 10 wilted completely, from full happy plants to wilted and near death. It's like they are in dirt and haven't been watered in 2 months. I've never seen anything like it. Tossed the 5, did a water change, put in 5 new clones, and I'm thinking that's a mistake. The last 5 bubblegum are now showing signs of the same wilt.
Went to the grow store yesterday to chat with the boys, fusarium wilt was mentioned and they gave me something called Sub Culture by General Hydroponics. Hoping for a miracle I put it in. The last 5 BG's are worse this morning. A cutting I took off of one of the BG's was put in water last night and has perked up completely.

Should I - toast the last 5 BG's, plus the 5 new clones I put in?
Try to save the new clones, take them out of that system, clean the system with bleach, put them back in? If this is fusarium wilt........

I'm pissed, I have no smoke, and I don't know what to do. Not the best of pics as the lights were on but this may give you an idea. It was taken a day before I decided to toast the first 5.

Any chance we could get more history? What nutes at what strength? Lighting? PH? Every little bit of into helps......

are you sure they arent getting over watered? It looks the same. Have you tried H2O2 to try to get some more oxygen to the roots? I am of course going to assume pH and everything is within spec. How about water temperature? is there any algae? Root rot? How have ambient temps been? Did you get the 5 wilting clones from the same mother plant as the other 5 that are doing ok?

what type of system?

Sorry, I should have given more info.
It's a small room, 12' x 7'. Two 1000 super hps lights in the enclosed shades with the heat vented out of the room. Room gets to about 24 - 26C max now, before the shades, I was hitting 34C.

Before we moved, in the old house, I had a 250 sq ft room for my grow room. Ran 6 1000's, hps lights, using a bucket system and pulled off 10 - 12lb each and every time.

Moved and set up the two rooms, the other is about 8 x 7'. As I mentioned in the first post we've had nothing but problems since moving. The rooms are smaller so it's been harder to control the environment. The covered shades have helped considerably.

Ph is always 6.1, use RO water. I use the Quick Grow 3 part nutes at about 070 ppm. Use Hydrozyme and Plantroids. Weeks 1, 3 & 5 I spray a solution of Bud Bloom Plus. Week 5 I start using Bud Boom in the rez.

All 10 of the Bubblegum clones came from one plant which is currently in bud, that was part of the OD on Carboblast room. So sign of wilting on any of those plants.

From what I've read up on Fusarium wilt I should probably burn everything that is in my basement?

Oh ya, I use a trough system, 6" web buckets, lava rocks on the bottom, clone in rockwool on top with rocks spaced around, the feeder line is constant and at the bottom of the bucket. I've used this system for at least a dozen grows and not had this issue. All plumbing and poly is changed for new every second grow and cleaned thoroughly between.

man you got me. Hope you figure it out. I'm assuming your ppms are 700--I'm not familiar with quick grown but I have some plants that really jumped in size one week and wilted within about 36 hours. Turned out to be a copper deficiency i believe---looked like overfert but the plants got worse and worse the more i diluted the nutes....mine started at 900ppm (Botanicare) and as soon as I upped the nutes to 1200 the plant came right back. 700 sounds kind of low to me after that experience..

well 1st hydro ph should be 5,8 or lower during flower, and all that spraying you are doing is probably frying your plant foliage! if it is not a typo...you posted mute strength at 070...that is similar to "none" if you mean 700, that is ok, but real light. clones take the age of the mmother...Once they root you can nute.

You maybe should quit all the extra fancy stuff and use 3 part w/the addition of calmag plus to replenish minerals/beneficial elements taken away by ro process.

vgoodlcuk.
