hey guys Ive been having this problem for a few weeks now, ive looked on many forums and even posted my own. ppl have given suggestions and solutions but none have worked and people seem to have lost interest in my post.

My plant leaves started to curl upward and dark patches appeared on those leaves. my temps and humidity have been perfect and ive had a good watering and feeding. the most recent attempt was to transplant to a larger pot and trim the dying leaves. ive done that, and now its been a few days since ive transplanted and trimmed the curl leaves. now more leaves have started to curl the the same as before with the same yellowing and dark patches. Here are some more pictures

With the info provided so far I am curious as to what your nute's are? NPK ratio? Looks to me like a phosphorus deficiency from looking at the leaves.
Curious what soil your using? Shouldn't have to add nutrients if your soil is complete. I would raise the PH just a tad in soil closer to 6.7 or 6.8.

NPK is pretty low but I thought my nutes would be making up for it ..... N-6 P-4 K-4. The soil is just multi purpose Pro-Mix

I don't understand why you have to add nutrients. How old are these ladies? I use soil and I have not yet had to add nutrients because my soil has all she needs. Just add water. Check out Sub Cool super soil recipe in the organic section.

As an example check out my blue cheese in week 5 from seed. She is sitting in only a cloth pot of Black Gold potting soil (the kind with the mater on the bag).
Look how luscious she is at 5 weeks all I did is put this seeding into a bag of black gold potting soil and ensured she has plenty of light access to water.

Okay here is what you do, you got to flush her, distilled water 7.0 ph room temp, and transplant her to good organic soil. Such as the one I recommend just look at the pic at five weeks compared to your 9 week. She will need to clam herself afterwards this is where you need to be patient and spend you next week learning how to mix super soil. Cause once she recovers from her sabbatical of force feeding her, then she will be ready for super soil, just add water and watch her grow...

What's your watering schedule like cuz she looks over watered as well as P&K def...what are you feeding her? Looking at pic 2 you seem to have a toxicity going on, (nute lock-up due to high salinity)..she looks wet but I'd flush w/ PHed nutes and let her set for 3 to 4 days and see how she does..and a flush is 3x the size of your pot...3gal pot = 9 gal flush and so on...good luck man

Watering about once a week maybe a bit longer. usually when the soil is dried 2'' down. she gets General Organics bio grow line once about every 3 weeks

I am not sure the exact numbers off my head, I guess I could find them. But I just know our lovely ladies as love it and thrive it in and it's just add light and water concept. Keeps it easy mistake free. Anywise the idea is not to have to supplement. I think your baby has gone through too much shock and awe and just needs to chill in some good soil and not feed anything for awhile.

This is my baby at nine weeks.. light soil water, no additives or preservatives.

spraying with anything? I had something like this going on and I believe the problem was the neem oil spray i was using on my plants (too strong). I have not used it for two weeks and everything is recovering except for the bugs. Anyways, if it doesn't help you maybe it will help someone else. Good luck.

I missed this, the plant is nine weeks old and your in the fifth week of flowering? Your light schedule says 18/6 them be veggin hours... 12/12 is for flowering and you need to get her healthy and well established before thinking of flowering by the way. I think you know this, just want to be clear.

Give her some rest in good basic organic soil, let that be her only source of food for now. So patience is the game, light and water should be your only concern right now.
