Sativa Flo pale and crispy

[Megawattfarmer]

Once again I come to bow down to the Grow GODS and pray for guidance.

My runted and stunted seedlings are now 24 days into flower.

Strains: 3 and a half DP Original Flo's (dropped one, broke it and am growing it in two halves) 2 Bagseeds.

Temps: 75-65 degrees

PH: 6.5'ish

Soil: hyponex and generic soil with 25-30% pearlite

Nutes: Earth Juice Grow, Bloom, Catalyst, Microblast, and Maxicrop for K. Pots are a little oversized so I'm only watering once every 3-4 days and giving mild-regular doses of nutes about every other watering. Got the Maxicrop because I was suspecting a K deficiency and only dosed once about two weeks ago along with 1 tbsp/gal of Grow. Last nuting was 1 tsp catalyst, 1 tsp microblast, 1/2 tbsp grow, 1/2 tbsp bloom. Used to be 1 tbsp grow and 1 tsp bloom, but I'm trying to transition to the bloom nutes and am planning on going to 1 tsp grow and 1 tbsp of bloom.

light: 400W HPS

I have been trying to listen to the plants, but not hearing anything lately. I can't tell if they have too much nutes or are def. in something. The only thing not in the nute program is Calcium. Anyway, the Flo's have started looking pale green on the bottom leaves so I opted for more ferts. The day after the last feeding the Sativa flo which was the most pale-green to yellow wasn't too happy. The smaller bottom leaves were very yellow and fell off with the slightest touch.

I haven't grown a Flo that was so sativa dominant before or any Sativa for that matter. It has droopy leaves, but I think that's normal? I water and feed all the plants the same, but the Sativa seems to be the least healthy. Here are some pics.

Is this nute burn on the Sativa? The pale color doesn't show up very well on the pic. I can't get a good pic until I can pull them out of the cabinet.

Oh, I almost forgot. The pale leaves on the flo's also have red leaf petioles, which makes me wonder if it may be phosphorus def. I'll try to get some better pics....

 

[Megawattfarmer]

Here's a pic of one of the bottom leaves. P deficiency?

Anybody?

 

[hogwild]

sativas are naturally less robust indoors than indicas, sativas really love the outdoors and side by side to an indica it can look sickly sometimes indoors.. That being said you might want to try watering with slightly lower ph water, maybe 6.2 would be a good starting point, and try to see if the plant responds positively, also try one tsp epsom/ gallon.

 

[Megawattfarmer]

Thanks hogwild, I will try lowering the ph a little.

I'm noticing more yellowing of the leaves on the other plants too. I'm pretty sure they need more bloom formula. I don't think that I'm overfeeding - wish I was better at this...

 

[Megawattfarmer]

Anybody??? I don't wanna beg, but I will. The yellowing seems to be worse. Here is one of the bagseeds I'm growing.








Thanks for any help guys. These girls are starting to get pretty frosty, so I don't want to mess them up any more than they are.

 

[Megawattfarmer]

Anybody out there? Please let me know what you think. Thanks.

it kinda looks like nitrogen burn, because its working its way up the plants from the bottom. I would only use bloom ferts from now on and possibly only water for a while and don't pick the yellowing leaves off because that will only make the burn spread faster.

 

[Megawattfarmer]

Hey Dank1,

Thanks for stopping by. It doesn't seem like too much N to me because the plants aren't very dark green overall. Also won't a mobile element deficiency work it's way up from the bottom?


Edit: Here's a pic that shows overall light colored plant.



I guess I'm leaning toward not enough magnesium? I might try the epsom salt with plain water next time...

Doesn't look like mag to me at all. My guess (from reading the infirmary, not experience) is you have a N def, a little P def, and mabye even a little Cal def. The ph you have listed is that your solution ph or did you test the runoff? I would double check the runoff ph, then plan my strategy accordingly. More than one def to me stinks of ph issues.

If the runoff ph is fine, I would run 2-3 gals of plain water through the pots on next watering, and then give full strength bloom ferts for 2 feedings in a row. After that I would go back to the recommended schedule. If your runoff ph is out of whack though, you will have to get that under control before you do anything else.

I'm kinda dumbfounded then from the first pics it looked like it was working its way up but if its not, thats is a whole different thing, you may just want to go to straight water for a while and see if it works itself out.

It doesn't look too bad to me, to be honest. Though I would say that the brown tips/fringes of the leaves suggest a slight imbalance somewhere.

I found that the lowest leaves started yellowing within ten days of applying bloom nutes - to all my plants, not just the Flos. If the buds are developing fine, which they look like they are, then I think it's generally healthy for the bottom leaves to yellow up - they're giving up their stored food to the bud development. There's proportionally way less N in bloom formulas than in veg.

I'm always surprised to see plants here shown 'at harvest', with dark green shade leaves - that should never happen. I don't expect to have any shade leaves left at all on most of my strains when I pull them, though I let them drop off rather than pull them off.



BTW, red/purple stems/petioles are entirely normal for Flo - not a deficiency at all. Check my gallery for the evidence...

 

[Guest]

Oh, now you just showin off EM, hehe

It's definitely affecting the lower leaves more.

- Wiimote
Thanks. I haven't checked the runoff for quite a while. I read on here somewhere that if you check the input pH every time, you don't need to worry about the soil pH. I'll def check tho. If it is a bunch of deficiencies, I agree it sounds like some sort of lockout (over-watering, pH, living wrong , etc... )

It's your awesome looking Flo's that made me realize that mine could be much healthier! I just checked some pics from my first Flo grow and saw the red petioles. I know each grow is different, but here's a pic of the first grow at the same stage of flowering (no noticeable yellowing) and one of how they finished.






I did have blood and bone meal in the soil mix on the first grow and only have a small amount this time. I am trying to decide what will be least harmful to the plants at this point. I am thinking about letting them get good and dry before the next watering and just using plain water since I've given them nutes the last two waterings (very mild on the last). The problem is I only will water every 4 days maybe 5 this time. So if I only feed every other watering, that's every 8-10 days. Is that enough?

 

[Elevator Man]

Wow, that's bushy Flo! I've never been able to get mine to do that! I'm jealous man...

But I see what you mean about the difference - maybe it is the blood and bone meal that's lacking. I know DJ rcommends those kind of nutes over bottled. But I've been using Canna this time in fresh soil with no supplements other than Canna additives, and they've looked perfect for the first time ever. My purple one suffered in previous grows due to incorrect nutes, and the shade leaves would dry and curl up, and then fall off, leaving the buds way underdeveloped. Way worse than yours though - really sick.

I would think plain water for a couple of sessions would hopefully fix it - I've kept mine at pH 6.5 throughout the grow and they all seem to like that...

I got a couple Sativas 28 days flowering and they have started dropping their bottom leaves, and small leaves on buds drooping. I'm in hydro, but I added a little cal mag, and they perked up a bit. None of my Indicas were affected.
