@libre how are you doing ? please keep us updated with some insights about your last season Purple Haze x Malawi harvest!

congrats on your harvest @Kiefcake i know the firsts indoor grows with tropical sativas are never easy .... but you learn a lot!
Some growing variables can be adjusted to improve the outcome, the plant looks like was grown with incorrect ph as you correctly pointed out, it was also overfeeded and probably flowered under too high temps. Even when growing tropical sativas, you get best quality flowering under slightly fresh temps. Quality drops if they are flowered with temps close to 30ºC or higher, particularly indoors where these sativas feel more constricted, especially even more when flowered from seed in a small tent.

The new clone looks super healthy and elegant i'm sure it's going to get better and better with more runs.

Hi Emeraldo thanks for choosing Purple Haze x Malawi and ACE genetics, much appreciated!
Those seedlings need a transplant! All the best for this outdoor season.

Appreciate it!

Yeah, for sure you learn a lot! The hybrids in the same soil mix handle a much wider range of conditions.

I agree, I was thinking the same thing looking at how healthy it is this time, I think I'm getting my soil mix nailed down a bit better. I just finished 1st year of organic soil, and it's starting to pay off big time. The golden tiger that's a few weeks from finishing is the best run of it so far, it still has all the leaves, and strongest terp profile yet.

As far as the PHM temps, it was flowering through the coldest months, and I had trouble keeping the room warm enough, I could barely break 70F somedays as the high, and it was routinely getting down in the 50s, so the soil stayed wet for too long of periods which I believe contributed to the issues. Part of which was a massive fungus gnat infestation that resulted, and the ensuing treatments / soil drenches wasn't kind to any of the plants, and completely ineffective in treating the issue. It wasn't until the warm temps returned in April that the soil could begin to dry enough.
Now come August, my temps will get to about 95 with the little AC unit running in the room, but I started winding my timer back a few days ago, and over the next month or so will bring to coming on at night time.

I very much appreciate your feedback, which is a huge bonus on top of the great genetics.

The smell of this plant is quite peculiar, can't wait to see how much it improves with better living conditions.

The more I think about it and jog my memory, there were definitely some days of temps being too high. I put a heater in the room trying to bring temp up, especially at night, but I live in a subtropical area (cant wait for legalization so I can flower these sativas outdoors) and our weather is pretty crazy, so I'd come home from work and the heater had been on all day, and the day temps outside would get to 70, and inside the room the temps would get outrageous when that happened, so after a few times of that happening i quit using the heater.

Before this next winter I need to get a digital Heater. Or better yet a new window unit with heat built in

Thanks Dubi. Yes, the Purple Haze x Malawi seedlings grew so vigorously, and they got big quickly. Now I've up-potted all four into larger pots with more room for the roots. They are beautiful plants! Will post more later. Cheers all!

Also PHxM, recently up-potted. Cheers all

Here are my 4 PHxM, now 7 weeks old. They all show yellowing on the older, lower leaves. Since all of the plants have some yellowing, I figure there must be something missing in my soil mix. From the look of the yellowed leaves, I thought it might be a K deficiency. A potassium deficiency would make sense to me because most the K sources in my soil mix are mineral based (kalium-magnesium, autumn fertiliser, and rock dust) and may need more than the 4 months since February to break down. Am using kelp meal and, for immediate availability, seaweed extract to provide K and counteract the deficiency.

The 1st photo is of the whole group, the second is of the plant that suffers the most. On that second photo, please note the half-burnt-off leaf in the center at the bottom. What do you all think the problem is? If it is a K deficiency, what is the best way to correct this now? Is seaweed extract a good way to go? If not, what else could it be and what can I do? Is this something that will go away as the plant matures?

Am concerned that this yellowing might continue despite my efforts. The new growth is not yellowing. Has anyone had this issue with PHxM? My Malawi and Super Malawi Haze don't seem to have this problem.

Any help on this would be very much appreciated. Thanks

Hi Esmeraldo!
Until someone with more expertise chimes in, here are my two cents:

After being root-bound, or stunted for any reason, my plants tend to take forever before they kick off again.

Particularly if the soil mix is a bit on the hot side. And I typically overwater them after transplant, too.

My gut reaction to your plants are that they are still in recovery mode.

Could over/underwatering be a contributing factor? Is the water source clean, and the pH good?

Wishing your plants a strong and healthy recovery, soon!!

 

[Emeraldo]

Hi Onboard, thanks for your input. The plants were never root bound, nor overwatered, nor is the soil on the hot side. The soil is a low-N "haze light" soil mix, with very little N, specifically mixed for Ace' s PHxM.

Underwatering might have been a factor. Since the weather heated up am giving them lots of pure clean mineral water every three days, pH'd to around 6.7. Soil pH is 6.3.

I think they are already recovering. Today I looked closely and saw the yellowing is actually improving, turning green again, after mixing seaweed extract for K with their water last week and spraying them with epsom salt solution via foliar feed for magnesium.

Cheers

Excellent, that's great!

Hi Emeraldo despite your pots have a decent size, they are only half full of soil, therefore not fully utilized.
Take in consideration that in good conditions the root system is equally big than the size of the outer part of the plant, so the roots of your plants must be touching (or will do soon) the end of their pots.

Plants hardly recover the yellowing of older leaves, you must look at the new growth to evaluate if they like their soil. Underwatering with plants under sun also produces yellowing.

 

[Emeraldo]

Thank you @dubi. I've made some stupid mistakes here. I have a limited amount of soil and have too many plants. Some of the plants have only half full pots, maybe one gallon. Those with 2 gallons are doing better with better water retention.

Temperatures have been exceeding 30C for several days, and in the heat of the afternoon the stone floor is way too hot for the roots in this situation. Yesterday I had several plants wilt and needed immediate watering!

I am adding soil to the less full pots to give more water retention. Just topping up, not re-potting to put soil underneath the roots. Am concerned it may be too early to transplant again after only ten days.

I am moving the plants today to a different balcony where they will have shade during the hottest part of the day and the stone floor will be cooler. Will transplant again soon, in the meantime looking for other ways to help them survive the heat.

Also am watering much more. Thanks again for your helpful comment!

Cheers

P.S. here a photo of PHxM (back row) with Malawi. Malawi being very robust, did not show the same symptoms from heat, under watering, and even K def. PHxM seems happier today, we'll see! All in all it is good to see the green new growth on top.

You should try nematodes next time, best way to get rid of those fuckers. I had been battling for months those in my mother plants with spinosad, sand on top of pots, diatomaceous earth, lost Golden Tiger 3 and Oaxaca x Panama mothers. Nematodes finally did the job, after a week or so, all gone.

I actually came across some nematode balls on ebay, right around the time it Cleared itself up, so I never got around to ordering them, but its good to hear about their effectiveness.

Could anyone please give me a general flowering time for the feminized version of PH x M? Particularly for indoor growing? Ive been growing south american sativas from ace so far but I think im going to run some thai and african crosses later this year for the fun of it

Hi mate,

Didn't see your question answered so I'll do it.
Had grown 2 Purple Haze x Malawis last year. Plant with more Malawi influence was ready at 15.5 weeks and Hazier one took 17.5 weeks (add additional 4-5 weeks from switching to 11/13 till real start of flowering). During initial stretch they easily gain 300-400% of height and that's for mainlined plants

I start flowering at 11/13 and gradually diminish it to 9.5/14.5. My plants were started from seed. Clones should be some couple of weeks faster...

Hope it helps a bit.
Cheers,

Thanks for the feedback my man. Ive already decided against growing this strain indoors but I look forward to an outdoor grow in a few years. She sounds stellar!

All 4 PHxM have been topped and am waiting to see signs of sex. They've responded to the warm weather (steady circa 30C) by bursting upward, and I topped them lest they get too big and tall. With that kind of vigorous growth, I may need to top again. They seem to have left the stress of heat, under watering, and/or K-def. behind. New growth is lush green and healthy. Will up-pot females from 2 gallons of soil to 7 gallons for flowering, males to stay in a full 3+ gallons. Here photos from yesterday, the second photo shows the leaf symptoms have now been left behind, on the lower leaves only! As mentioned in the other thread, my 3 Super Malawi Haze have now matured and interestingly the SMH showed very little of those symptoms from which, now, happily, the 4 PMxH have recovered. It's fun to grow ACE strains, so very vigorous and robust! Cheers

 

[Mitsuharu]

Why not tie the big one down!? It has long internodes so...

Edit:
Oh, you topped them all, ok, sorry.

 

[Emeraldo]

Hi there PHxM fans, my three beautiful female ACE regulars (Purple Haze x Malawi, Malawi, and Super Malawi Haze) have now been up-potted to their final destinations! Here I'll post a group photo and below a close-up of the Purple Haze x Malawi only (close-ups the others will be posted in their respective threads, of course!). I am hoping for a male PHxM as well since I am still not sure the female will finish well in my climate at 47N (the greenhouse will provide shelter and heat come November, but who knows?)... At the very least, with some PHxM pollen I might get a cross with some of her traits, hehe, hope grows eternally.
