Indoor Anyone Know What Lime Burns Look Like?

I posted a while back about OF soil that was very acidic. I tried adding Lime to the soil. I started with 2 Tbsp/5 Gal and tested it and it wasn't enough. My runoff was still about 4.9. I started at 4.3 so at least I was making progress. So I added some more to my batch of soil and planted an AKR. It has at least 1 Tbsp Lime/Gal. This plant looked like it was going to be one of my best. I tested the runoff at week 4 and it was 5.6. I was obviously surprised the PH wasn't higher. So I took the top inch or so of soil off, mixed it with more soil, added 2 more Tbsp of dolmitic lime and put the soil back. I figured this was better than just spreading the lime right on top. This was on day 35. The next day it looked like someone had taken brown paint and splattered it on some of the bigger sets of fan leaves. I flushed a few gallons of spring water through just to make sure it was mixed in as best it could be. I was hoping it wouldn't get too bad but it's getting it's butt kicked pretty bad the past week. Here are some pics above. I was curious if anyone knows what lime burn looks like. It happened immediately after I added the extra lime to the top of the plant so it made me curious. Otherwise what do you think? Calcium def? Suggestions? The good news is the PH is testing much better now.

What age are the girls in the pictures?To much lime can hurt a plant.It looks like your girls are almost ready to chop and are turning yellow naturally.

Whoops! The plants in the pictures are not the ones with the problems. I had the right pics up but I must have deleted them by accident. I was going to also ask if these plants looked ready to cut so I had both sets of pics up. I decided they were close enough. These plants are 77 days old. I am placing them in the dark this morning and will chop on Monday. Ok, I will go post the right pictures. This is what happens when you post in the middle of the night after a cocktail.

Here are the correct pictures. Sorry. My post must not have made any sense with the wrong pictures up.

Have you checked your PH? Is the whole plant that bad,if so its beyond help.Could be nute burn,lockout of phos and potasium.I would flush them and make sure ph is correct.Hold back on nutes and give only ph water for a while.

The PH was 5.6 before I added the extra lime. Since then the runoff PH is 6.5. And no the whole plant isn't bad. I'm sure it will survive but I was hoping someone would know if the lime was the cause. I was thinking maybe that much lime in the soil could cause a problem from too much calcium or magnesium. If you have too much of one nutrient you can lock out another right? I've also been using 1 Tbsp Molasses with most of the feedings also.

Did you use dolomite or hydrated lime? Dolomite is slow acting and I wouldn't expect you would see any effects from it that fast. Hydrated, on the other hand, could cause issues if applied at that high a rate.

I don't know if you can give them to much mollassis but I think every feeding is a little to much.Molassis contains calcium and magniesium witch should bring ph up,but excess could cause problems.

I used powder dolmitic lime. Do you think this looks like calcium deficiency or something else?

Cal/mag deficiencies usually show as round brown spots on the leaves. I'm thinking it was more likely a total nute lockout caused by your pH being so low. Keep an eye on them now that you've got your pH back up and see if it continues or stops now.
