LEAVES DYING FROM OUTER TIPS INWARD

[SeaLevelGrower]

I have 3 plants that I bought that were already in flower. All plants were in 5 gallon containers with a very sandy compacted soil...I transplanted them into 10 gallon pots using Roots Organics soil. Unforntunately I dont know anything about where the plants were or what their feeding schedule was...by the looks all 3 plants are at different stages. The UK CHEESE is the eldest...approx 4 weeks into flower. HEAD CHEESE approx 3 weeks into flower. SUPER GRAPE APE approx 1 week into flower. I will never purchase plants again that are this far along, however they were VERY healthy looking when I brought them home from the dispensary. My problem now is that the leaves are dying starting from the tips moving inward until the leaf is curled up and crispy burnt brown. My temps were very high for the first week or two, but I switched the lights so that they are on during the night instead of during the hottest part of the day. The temps are ideal now. The UK CHEESE has great sized buds on it, but all of the leaves are dried up and crispy...even the buds are beginning to get crispy as well.

The pictures are the different stages in my leaves dying off, the final picture is hard to see anything because I took the pics with my phone.

Hopefully I have filled out the trouble shooting guide enough for someone to help me figure out whats going on!

Thanks in advance!

This picture says it all....

They look to me to be a little further along than just 4 weeks of flower, that last pic looks ready to harvest (just judging without seeing trichs close-up).
No matter what happens here in the coming days, it looks like you'll have a nice harvest.

The only thing that looks peculiar to me is the runoff pH, you said it's coming out at 5.4. That would mean your medium is that low or lower to bring your water down that low. Lockout will happen just as easily at the low end as the high.

My 2 cents at 1 a.m., hope this helps some.

I would agree with irydyum. It looks like your prepped for harvest. No fan leaves, and plant is pulling nutes from anywhere. Not necessarily a bad thing. It will expedite your harvest time. JMO.

I would agree with irydyum. It looks like your prepped for harvest. No fan leaves, and plant is pulling nutes from anywhere.

From the second pic, it looks like at one point either nute lock, ph issue, over fertilization, and over water on a short period of time (flush and clear). Was the picture spread in time over a week or so with the leaf shots and bud?

its okay, and it looks like it recouped - JMHO.

I guess I should have mentioned that I have had the plants 3 weeks now...so the one plant is ready to harvest...just watching the trichomes ripen up. However the other two plants still have 2-4 weeks in my opinion, again, Im not to sure of the actual age of these girls. With that in mind, do they still look okay?

Thanks...
