Interveinal browning and upward curling

Here is what I am working with:

Smart pots, canna coco, canna coco a and b.

The strains are Blue Dream and Jilly Bean. The plants looked fantastic last night. There was absolutely nothing wrong with them.They where perky happy girls. I transplanted them into 5 gallons, nuted them at 1.2 EC (@ 500) after bring the cal mag up to .4 EC, with a 5.8 p.h. Then I put them into 24 hours of darkness and checked on them when the 12/12 started and this is what they looked like; drastic interveinal browning and upward curling of the mid and upper leaves and droop. I already removed the fan leaves that were over 50% brown. The Blue dream have just slightly developed symptoms of browning or cellular collapse but are quite droopy. The Jilly Bean is 20-25% damaged but still perky. Did nuting them and immediately putting them in darkness possibly cause this. Thank you so much for any help!

Have you transplanted recently? do you spray anything on them ever?

I had a situation just like this and it got better, I went at it hard. I think the root of it is deficiencies. If the nutrients have not gone past 500ppm that is a problem. You should get a decent runoff 10-20 %everytime and always use Cal-Mag. My gut tells me that me that you are Phosphorous deficient. NEVER use plain water, at least have 100ppm of A, 100ppm of B, 100ppm of cal mag it keeps the ec from rapidly swinging. Make a 300 ppm as I described and get the ph to hold at 5.8 in the resivoir for a couple hours before you flush. Coco is naturally at 6.1 ph so a flush brings the root zone back to where it needs to be(5.8). at the point where you still have enough solution to hit each one with a final pint raise ppms back to 500 and and Get a qt spray bottle and add 1/4 tsp of cal-mag and 100 ppm of the fertilizer with highest P and K. use a wetting agent(if possible) and distilled water or RO water. 1.5 hours before lights on spray em well, wait a half hour and do it again. They need to be dry before lights on. Get rid of any dead leaves prior to spraying . it is typical for a droop after a flush so foliar feeding lets the coco dry for a couple days. Next feeding go to 750. Get some liquid Karma in the mix and an enzyme to help the damage to the roots. in 5-7 days you should be a lot better off. The possibility of a fungal or bacterial infestation has increased because of the presence of dead leaves. You should treat them as if they did, I use greencure on the leaves and h2o2 on the roots(look up dilution ratio) each of these steps should be done with a day in between. That should be a well rounded treatment. Get to 900ppms, and hold it there. I use more products and if you want to know anything else hit me up. Good luck get me those pictures tomorrow and new ones 2days after. Good luck.
