Well, we have a couple Arjan's Haze #3 that we've been growing from feminized seed, and Franco suggested keeping everyone posted here, so I'd like to show how they have been coming along so far.

They've been growing underneath 4x18 watt Grow-lux fluorescents, 6500 lumens total, and are beginning to be introduced to the 600 watt HPS. They are four weeks old now.
The missing leaf tip on the one is due to a mischievous, pot-head kittie.





Here they both are, two weeks old (with a White Satin on the right):





Here is the first phenotype, every three days after that, ending with a side shot from today:









And the same thing with the second phenotype:









And, just for the hell of it, the last group shot of them with their fellow White Satin and Critically Smashed sisters:





Thanks for checking, and thanks to GHS for the genetics!

looking good Sirius.
Is that coco there growing in ?

petal

p.s. is that the ladies relaxing in a jaccuzi ?

[Sirius]

Hey, thanks for the reply!

Yep, its coco. Using Atami Coco A&B for the nutrients, and just started using their Atazyme as well, so hopefully that will create a boost in growth.

Its a jacuzi bath, they get put in there for watering since its a lot easier.

was looking like they were ready to get all wet.

I've got a single femed Arjun Haze #3 ,about 3 weeks old, but not under as much light & in soil, she looks healthy , not as developed as yours.

hope you keep posting your grow

Very cool thread Sirius, well done man! The AH3 likes coco!
Respect, and keep us posted, we wanna see it budding!

Well, this update is more of a seeking some diagnostics as it is just another peek at the plants. A few days ago some burnt edges started showing up, as well as some loss of color. We had some magnesium deficiencies early on in the grow, that was quickly corrected with some bionova magnesium. It seemed like it was showing up again, so we gave it a boost of magnesium again, but this time, I attempted to keep the right ratio of calcium to go with the magnesium (got a bottle of bionova calcium as well). Well, there was a typo on the bottle, which said it contained 1% of CaO instead of 15%, which was discovered later on their website. Suffice to say, they received a couple more mL/L of the stuff than they should have. This is when the burnt edges really became apparent.

Well, then I realized that, considering how much calcium some bottled water I was looking at was said to have, I figured the tap water must have a good bit too, so now they are being watered with 1mL/L of their Atami A&B, and about 50ppm of magnesium (the A&B only has 15ppm). They were flushed a couple days ago as well. Since, the problem doesn't seem to be getting worse, but the Arjan's Haze #3 definitely look much worse for wear than the other strains we are running. It really seems like a magnesium lockout due to them receiving too much calcium. I'm wondering if it could just be a general over-fertilization though? pH has remained at 5.8 all the time.

Anyways, here's some pictures of how they look right now. It might be harder to see in the pictures than when you're just looking at them, but they have a really lime green color about them, between the veins, closer to which it is a regular, darker green. The newer growth in the developing side-branches shows no signs of any problems. Its our first indoor grow, so its just in the order of learning how to dial in nutrients, I guess. What does everyone think?

They were looking happy, at first then arrrrghh. I think natures way is to repair. Good Luck with it.

Yeah dude, it was really disappointing to find this happening and then to realize it was due to a mislabel on the calcium bottle, especially when there was already a slight Mg deficiency and I was just trying to apply what I was just learning about keeping Mg and Ca in some sort of ratio... Ahh well, they haven't gotten worse, and after the watering last night, we'll be able to see soon if the lime green starts going back to normal...

Phenotype #1 looks a lot more healthy now, and #2 looks a little worse off by comparison, although its starting to perk up too. I really think this is because #1 is bigger and a little more vigorous, and have managed to recover faster because its got more photosynthesis happening. This theory seems supported by the fact that the more indica-leaning White Satin and Critically Smashed didn't show nearly as much stress from it all, and they've got those huge, thick leaves...

[franco.gh]

they'll get back, no problem. Implement a good flushing program. It always helps.

[Sirius]

We flushed ten liters of water through each pot a couple days ago to help clear everything out. Trying to find the right balance of magnesium and calcium to help get some color back into the leaves.

Franco, does it look like problems with calcium or magnesium, heat stress, or a combination of both (the deficiency making the edges weaker, opening up more potential for burning)? We found out that the temperatures underneath the HPS were getting a lot hotter after we would put the plants in there when it looked like the temperature had become stable and low enough. We made an adjustment in their location so they have more from the air conditioner flowing on them, and its down to about 25C about a foot underneath the cool-tube, so hopefully now, between that, and getting the nutrients back on track after that mislabel mishap, we'll see them get back on track. I'm just wondering, though, if our assumptions about what happened would look to be accurate - let me know!

Oh, and one more thing. I know I've seen you mention the EC of your nutrients at different times for this strain, in the video I think, but I was wondering if you might know a little bit about what the optimal ppm of N P K Mg S Ca might be? If not, its cool, but it would really help me find the right balance, since I don't have an EC meter and profiled my nutrients. I just received some Apollo Mist seeds as well, and having a better idea of what to feed more sativa-type plants would be great, since I can't risk anything with those rare beans. Any help is greatly appreciated, man!
