Veg Room Plants are Sick need help please

I thought I had a calcium/magnesium deficiency due to using RO water and not adding Cal/Mag and possible over feeding plants in Fox Farm Soil. I have had two waterings since with only RO water and Cal/Mag supplement at 1ML per gallon as instructed. Plants are not getting any better after a week.

How long should it take for a nutrient imbalance to be resolved?

Do I have another problem?

IMO I would change the pot with one that is bigger than the one I see under the plant, Transplant her and don't give any nutes for a few days 4 she should bounce back okay.
I believe that fox farm is hot already so be careful not to add to many, Is that a clear pot to? Use black it works the best, and also check for salt build up. Those leaves curling up seem like you may have some over fert problems, change pot with more soil and give her a few days see how it fares.

What else are you feeding them besides Cal/Mag? What's your nitrogen source?

Thanks for the input and help!!. In my grow room, I have 3 different varieties vegging. The pictures I sent where for my (2) Liberty Haze plants. I just repotted them into 5 gallon containers (black) 4 days ago with fox farm ocean forest and have been giving them RO water plus Cali Magic at a rate of 1 tsp per gallon. My plan is to just give them RO Water + Cal Magic until I see some improvement as the Fox Farm Soil should have enough nutes until they recover. The other (2) varieties in the veg room are Chocolate and Critical Kush. These two varieties are doing much better and I have been doing the same nute schedule for all (3) varieties in the veg room. For some reason the Liberty haze did not like it.

Going all the way back to the beginning: For this group of plants in Veg, I decided to start giving them nutes 2 weeks into the Veg cycle. I was feeding them IONIC Grow (see attached file for label) at a rate between 400 - 500 ppm's. I also didn't realize that RO Water needed Calcium and MAG supplements....so I think I overfed them which amplified the calcium and mag deficiencies...

So if I am on the right track, my plan was to only feed them RO Water + Cal Magic until they recover. My question is how long will it take until I see if this is working. The fan leaves that were sick before are getting worse and it's hard to tell if the new growth is affected.

Well if it's just Nitrogen it can show signs of coming back in 3 days, but if it's the Cal/Mag it can take 7 to 10 days.

Are you checking your runoff? And if so that will be the best indicator if you are defficient, or over on nutes. What is your ph. Im thinking if its older, lower growth you are N deficient. Maybe even locked from a bad PH. Take a ph/tds reading next watering and that will help you the most.

I needed to water today so I took the opportunity to give them a good flush. This time I didnt add any cal magic and just flushed with RO water. PPM's were over 2000 so this confirms an overfeeding. I continued to flush until PPM's were under 1000. I trimmed all the really bad leaves and put them back in the grow room - hoping for a full recovery

I have learned a good grow lesson - less is better when it comes to nutes and I wont make that mistake again. I truly appreciate all the feedback from you guys - this site rocks!

Cheers and good luck. I find running straight water 1 out of 3 waterings works best for me.

Grow Room Update - all of my babies are looking much better now - thanks for all the help in resolving this issue!! Will be moving the Liberty Haze into the fower roon in about a week. need to repot first to 7 gallon pots. The Critical Kush need a couple more weeks of Veg and the Chocolates are still babies. New Pictures attached...just for fun I included my flower room pics where the Chocolate Kush are 5 weeks into flower.

I Love #7 pots! Looking good man. They will get big in that pot. My Jupiters go bananas in #7

Yah me too - All of my plants in Flower now get the 7 Gal Treatment = I think I need to start staking them they are getting so big...
