Dying plants, please help.

I only have four plants in my grow, two bubblegum and two blue dream. Everything was fine and growing great until we moved to our new place on Oct 4th. Here is the setup: 4x447 grow tent, 600w HPS, carbon filter/fan combo, and extra fans. Fox farm soil, fox farm liquid grow and bloom. Stopped using tap water about 2 weeks ago and now only water with fresh water from the local aquifer.

As you can see from the pics my two blue dreams are crisping up. All the leaves protruding from the buds have turned brown and are crispy to the touch. They have been flowering for 44 days, and at the rate of decline, these babies will be dead within the week.

I could use some advice of what could have gone wrong here. The two Bubblegums are growing great still, no problems. There are no bugs as I can tell, I usually have hawk eyes for bugs and know how to treat them. I assume no amount of help will fix these plants at this point (unless a flowering plant can produce new leaves?), but I need to know what I can do differently for my next grow. Also, if the plants die next week, could I harvest early? Would early harvested bud have much THC?

When I first noticed these symptoms I thought that the plants got burnt...one day I had the light on 100% (its usually on 75%), and 3 feet away from plant canopy. The temperature inside the tent soared into the mid 90's for a day, and I thought that this caused the leaves to burn. Im no expert tho.

These pics are from 4 days ago, the problem has spread to 95% of the blue dreams leaves since then. It starts as small brown spots on the leaves then the whole thing goes crispy.

(I thought it could also be a salt or fertilizer build up in the soil. I realized that I was only watering each with a 2 liter and hardly any water would drip out the bottom.) Sorry to be long winded about this, but I thought I should give as many details as I can. The bubblegum's are doing well under the same conditions.

Wayyyy over something. Fertilizer, water, light or all, or a couple. Probably food. Buds look good. Test the ppm of runoff. If its way hot then flush them in the tub. You need runoff, salts cling to salts too. Wax in, wax out. Always runoff or you get a salt pileup.

is this your first time growing this breed? you have over-nute a little, but mostly? you are probably within 10 days of picking.. I have some breeds that look like this every-time at harvest time. its normal.. pick the dead leaves off, you should be in all water by now anyways? Leave the leaves that still have some green as the fruit is still pulling from these leaves. Relax and get a nice pair of trimming shears ready :+) Do NOT flush until the soil dries out, the last thing you want to do is rot your roots now.

Yea you need a nice long flush. It doesn't matter if the soil is already wet, because if you don't flush soon your plants could just up and die.

I'd run a good 1.5 gallons of water per gallon of soil. I usually do it in increments. Run a few gallons, let it drain, run a few more, let it drain.

Your plants will be kind of soggy and most likely in shock for the next week or two from the nute lock, but it should be fine. The end yield will be affected but it's better than no yield off a dead plant! Good luck bro

Also valid, but usually I get yellowing of the leaves from the bottom of the plant up towards the end of flower, never red spots on my leaves that fry the leaves from the inside out.

That's why I'm thinkin nute lock, but it's perfect timing to flush before flower anyways. But I'd let the girls flower an extra week to make up for the nute lock shock period

I tried to blow up the pics, cant see too close, I see nute problems but person has wet soil now. I was going to take some pics of two of mine since they are in the last week, they have almost no leaves left at all, just shiny buds and a couple leaves left, and like OP, I have wet dirt that I passed over watering today as when they get this close, they will not use as much water and I have rotted the roots before, thus I warned of this for OP to let dry before any flushing. I honestly see us both saying the same thing. I like the shout out to grower that he might have a " shock " that will delay his maturity date being pushed back a week or two.

True, the plants don't use as much water during flower, AND the added water could raise rH in the room causing mold problems if left unchecked.

SixMoreDucks you need to just use your best judgement on when to do your flushing honestly and just pay extra close attention to your plants for the next two weeks or so
 
Thank you so much for the advice. This is my first time growing blue dream, or any kind of sativa dominant strain.

Sorry about the low quality pics, I will take better ones tonight. I agree with a flush too, I will also prepare for that tonight.
 
Ok I flushed all my plants tonight. Also snapped some better pics.

After these pics I took some time to trim off dead leaves. I kept as many as I could, but honestly it's about 95% that browned and died.

The buds themselves are glistening, but will the bud have any quality to it? They have been flowering for 45 days.

For future reference, how often should I flush so this doesn't happen?

Next time, if it were me, I would go for 15-20% runoff each time you water. If you think you might be wasting nutes, you could water with just plain ph'd water in between feedings, and go for 20-25% runoff with the plain water, and less runoff when you feed.

I wouldn't chop For at LEAST another week, but I personally would wait two. One week for the shock, and one week because you said it had about another week till you were gunna harvest anyways.

And as for how to stop nute lock, I personally never flush. But every time I water, I give it a nice soak with fresh water first (about a gallon water per 5 gallon pot), THEN water with my nutrient solution. I believe it's called leaching. But basically it's like a mini flush before every watering with nutes.

And also make sure your watering with nutes every OTHER watering if your running full strength nutes. Your girls will tell you if they are hungry with a little discoloration on the leaves. Your better to under feed a little than to over feed, as you found out.

But you should be in good shape to harvest in a week or two! Let me know how the smoke comes out!
 
I checked the two girls tonight and trimmed more. They look like they are fully in the process of dying, possibly dead by morning. 99% leaves have dried.

The leaves around the flowers are drying up right into those nugs, starting to discolor them a little. I'M THINKING that I should harvest tomorrow before the buds degrade.

mr-moniker, I would love to wait a week or two but it really looks like they r about dead. Sad about it, but I do have more blue dream clones growing to replace them.

Like moniker said chop them. I'd personally try flushing first. they might still end up tasting like garbage. you might need to hash it.
 
I had two plants of mine looking the exact same way these are looking. They were yellowing/ browning and very dry/ crispy to the touch. I didn't look at it as over feeding in my opinion and that's all this is (my opinion) in no way am I saying ppl are wrong I'm just telling ya what went down in my case. I use canna coco a and b along with the canna supplements line, and I ph and check ppms all were fine. I decided to add cal mag plus to the regiment as browning and crispy leaves are also a sign of calcium def I also had purpling stems n leaves somewhat. After a week of adding the cal mag plus. No more leaves turned brown or yellow and all crispy feeling was gone and was back to a decent cool to the touch feel. Nice n healthy. And I didn't do any extra flushes. To be honest. Just the pre harvest
