Durban Poison Grow: Week 8 of flowering buds not fattening and dicolored leaves

[Bobcat]

No light schedule interuption but in the first two weeks I had heat issues.

[Sheesh]

I'm seeing signs of reveg too. Some of the leaves look smooth without the serrated edges. Was there a light schedule interruption?

[Burny]

Grown under 300 watt light with epistar leds.

[Flexy123]

You use one of these Chinese "300W" plurple lights, with possibly 60 (or 100) LEDs, like the Marshydro "300W" LED lights and countless others? (They're all the same really, based on these Epistar LEDs)
Then it's LIKELY that it's your light, and in particular if you grow a number of plants. (How many are you growing?)

Disregard ANY of these claims about wattages of the lights, because they call them "300W lights" 300W merely because they have 60 LEDs which can take a max. of 5W each, but in reality they are driven much, much lower. Besides, how much power the light takes is entirely irrelevant anyway since different types of lights can have different efficiencies.

I used to grow with these lights but NEVER flowered with them, they are simply to weak. The problem is not the light output per se (this, in theory, might be ok) but the poor spread of these lights (light might be "ok" if you have ONE plant right underneath one light, but not enough to cover a wider area) and their inability to penetrate far down through the canape. It's "ok" vegging lights and for seedlings and vegetables, but I doubt this will grow large buds whatsoever. So look into your lights, cannabis needs a lot as I am sure you know.

Have you had light issues during flower? That first pick looks like there is some reveg . 8th week of flower the only light green on the plant should be on the colas and only on the growth closest to the flowers. Even tho I believe that you are growing what I think is pheno B the roundness of some of the leaves make me think that you had some light schedule issues and your plant revegged.

Looks to me that ur doing a good job but are in for a 12 or 14 week grow just my 2 cents and let me tell u that u do not want to harvest early

[POKEDSMOT]

Yellowing of tips at this is normal 1/16-1/8 of an inch. Brown or rust spots on the leaves main bodies does raise alarm. Could be high nitrogen, low potassium, incorrect ph or a manganes problem. Durban usually packs density on during the last few weeks of Flower. Need some natural light pics but to me it looks like phenome type B genetics. What breeder did you get your seeds from? Type B genetics carry skunk#1 as added in the 70's to stabilize it for the European climate. Type A is the more desirable genetics and extremely hard to obtain.

[Bobcat]

Well honestly I learned something because I have always given my girls nutes with every feeding. Once I saw the tips change I went and bought a PH tester as well as PH up or down. I have been using Nebulas philosophy on watering and only watering when soil is dry up to my first knuckle. I took a few pics and have attached them. Tell me what you think...

[Mr Pot]

I've seen people watering with different frequencies because of the VPD discrepancies, but I think that's the first time I've seen someone water once a week. Do you measure pH? I've followed Nebula's GH Chart (that's a lower dose than GH Chart itself) and never had any major problem. Are you watering with plain pH'ed water in between waterings? Are you getting runoff?

If you're getting runoff and controlling the pH, watering once in a week or every 5 days shouldn't be a problem. I'm running three ladies and a few clones in coco + perlite and I have a RH around 65% here in veg, my frequencies are every 2 or 3 days. Of course this depends on how much water you're giving them and the VPD (temperature & RH optimal indicator) inside your tent but this frequency of a week did worried me. Anyway, I can be wrong but I would try to increase that frequency and give less water every time in order to get a runoff (if you're not).

The VPD chart is attached for you to see what I'm talking about (if you haven't already heard this).
Also I've noticed in my last run how leaves turned yellow and sometimes dead near harvest time, dunno if it's this what's happening to your ladies and if it's not I would go for overfeeding instead of a more "normal problem" like the one I had.

[stevenics]

Water, wAter, feed 50% of what you were feeding, Water, water, feed 50%. And continue like that until at least 50%c of the crystals are cloudy before you start your flush. When I first start feeding my plants in veg I start at 10% recommended dose and work up to 50 % , the only time I give more than 50% is if they show signs of nutrient deficiency

[Bobcat]

Ok and thank you. Should I start flushing them now or just keep giving them nutrients but less than I was before?

[stevenics]

I just looked at pics of your canopy again, and I don't see anywhere that needs any kind of defoliation. Unless there's fan leaves that cannot be seen in this picture, I would not cut anything at this point. PS, these buds look great!

[stevenics]

Don't do any major trimming right now, if u have large fan leaves blocking parts of your canopy you can remove SOME of those, but no major Defoliation at this stage in the poisons lifecycle.

Bobcat , them sativa buds ain't gonna look like indica bud. Thats some strong ass, bud Bobcat an DP is on my next grow list. Somebody will tell you more about it in a minute. New pictures would sure help cause I can't see em good.

[Bobcat]

Thanks a lot guys. I'll try to take better pics tonight and post them. I will say this, whatever the problem was it hasn't spread it's only on the leaves that were already affected. I do have another question though. Should I have so much leaf around my tiny buds? Or is it still early and buds should get bigger?
