Droopy and yellow. New nutes or new light?

[pickledLSD]

The plants are almost 2 weeks into flower and so far have been extremely healthy and perky except for some slight yellowing on the very bottom set of fan leaves. The ventilation is good and the temp never gets out of the 80s but it did rise about 5-6 degrees with the new light. I'm using my own soil mixture of some FFOF soil and some Jiffy soil with added perlite. The other night I added some PBP bloom, Liquid Karma, and Cal/Mag plus along with switching from flourescents to a 250w HPS. I added small amounts of each since this was the first time I've tried these nutes. The run-off PH was 6.4 after the watering and the plants were completely dry before I watered. The very next day they were droopy, had yellowed a little more, and the branches turned purple. I'm not sure if it's a deficiency, burn, or something to do with the light/heat change. Any help would be greatly appreciated. Thanks in advance.

Looks like run of the mill flower-stage yellowing to me......Could be a temporary shock from the light switch, though, but to be honest, I doubt it.

It's natural for leaves to yellow & drop in flowering, but not if it's massive quantities of leaves quickly. If that were the case, it would likely be a major nute problem. Just keep an eye on in, don't over-nute it, etc, etc.

I don't think there's anything wrong with it, though, just looks like normal yellowing to me.

Ok, thanks for the help. So there's no reason behind the branches turning purple and the whole plant going droopy overnight? These plants are almost 2 weeks into flowering now and looked very perky and healthy until I made these changes.

BTW: This isn't my first grow or anything. Here are a few plants I've grown so far. Up until now I've switched to a 70w HPS for flowering and always used Fox Farm nutes. Decided to go 250w HPS and Botanicare nutes this time.

Branches on my plants have turned purple from time to time, too. It's not a sign of disease or anything, it's just another color of the plant. Mine were always healthy, never had any problems, even when stems & branches turned purple. Believe me, when I pulled my first couple of grows back on OG, I asked about my branches turning purple more than once, and always got the same response---"It's fine, just part of the plant's make-up, don't worry."
If you really want to get confused, have a plant start out green, turn rust red, then purple, then blue, then fade back to green within 2 months of vegging time----No one could EVER figure that out But it was just the plant, she liked "changing her spots", I suppose.

 

[Nikijad4210]

As far as drooping is concerned, in all honesty, it really could be "light & temp" shock from the switch. Some plants are actually sensitive to that.
It's also possible that there might have been a bit of overkill with the nutes, but I haven't used the ones you mentioned, so I'm not going to speculate further, I just don't know.


Whatever you do, though, just remember to always not to take the first opinion as the golden standard---The more folks who help out, the better. My opinion's just one of many.

Alright. I really appreciate your help. I guess I'm going to move the light up a little bit and water with plain water next time just to see what happens. Then I'll ease the new ferts back in and see what I can do with the droopiness/yellowing. I'll accept the fact that yellowing/purpling happens but I do want to try to get these leaves perky again.
I can't imagine having a plant turn colors 4 times in veg. I would have freaked out.

Lol, I sure as hell freaked out over it, I thought I was killing it somehow. Now, though, I wish it'd hermied on me, just to produce even a single seed to re-grow. I'd love to have grown that one again. Smoke wasn't too great, but boy, hindsight's 20/20---She was damn purdy....

Any other opinions? I transplanted the day after the drooping started (which was a day before I started this thread). Tonight when the lights came on the drooping looked a little worse.I flushed tonight with plain water until the run-off PH was 6.6. I moved the lights up as well and managed to lower the temps to the mid 80s. Next watering I'll add small amounts of Pure Blend Pro Bloom, Liquid Karma, CalMag Plus, and Sweet. I guess I'll see what she does from here.

Here are some pics from tonight. Found a damaged spot on one of the leaves. Bud production doesn't seem to have been affected.

Isnt Cal resposible for red/purple stems??? Nitrogen can give purple stems also but you wouldnt have yellowing with N. So If I had to guess I'd say Cal defficiency with maybe a little bit overwatering which explains the droopy part..Just a guess though.

How often do you water??
RO water or tap??
What is the strength of nutrient?? PPM or EC??

 

[Gangabiss]

Sophisto, what do you mean you wouldn't have yellowing with N?? That is the classic sign of a nitrogen deficiency...

In my opinion you are overwatering and have too little nutes. Back off on the water until the soil starts to pull away from the sides of the container next time.

Maybe add a little bit of veg ferts also to keep the yellowing in check.

I water once every 4-5 days and trust me-the plants are completely dry and very light when I water. I try to flush about once every third watering, could that be part of it? I fed using tap water with 1/2 tsp of Cal-Mag Plus, 1 tsp PBP Bloom, 1 tsp Liquid Karma per gallon.I'm going to order a PPM/EC meter this weekend, it's about time I guess. Spots on the leaves are making me think I need to adjust my feeding mixture. She has perked up a little since I flushed her the other day.

I've never used any of these botanicare nutes. Any suggestions on a mixture of PBP Bloom, PBP Grow, Cal-Mag Plus, Liquid Karma, and Sweet? She's been showing a deficiency for quite a while now, but not the spots and the droopiness. I guess the best thing to do would be to wait for my meter.

Here's a pic when the only problem was yellowing. About a week before I tried the new nutes/light and started this thread.

Numbers are in parts per million; 1 teaspoon = 5ml ; ml per gallon (3.8L) of water

3 things you should be aiming for.

>at least 30 ppm phosphorus

>a ratio of potassium to calcium to magnesium of 4:2:1; if you got 100 potassium then you would want about 50 calcium and 25 magnesium; if your using dolomite lime you would not need so much cal mag in your water

>100 ppm nitrogen (low dose) to keep the leaves from falling off in flower


I was not sure which pbp bloom formula you are using with the cal mag plus...the hydro formula or soil formula? I will show you what your using both ways.

1 teaspoon pbp bloom hydro + 1/2 teaspoon cal mag plus

n 48
p 12
k 58
ca 36
mg 16

or...

1 teaspoon pbp bloom for soil +1/2 teaspoon cal mag plus
n 34
p 25
k 58
ca 36
mg 16

Either way your nitrogen is too low. That may be the reason for the yellowing bottom leaves.

Here is the answers...

11.36 ml per gallon pbp bloom hydro + 3.86 ml cal mag plus
n 100
p 27
k 131
ca 65
mg 29

or...

16.67 ml per gallon pbp bloom for soil + 5.8 ml cal mag plus
n 100
p 82
k 193
ca 97
mg 43

You can see with both examples we got 100 ppm n, at least around 30 p, and our k ca mg ratio of 4:2:1 is used.

Final comments:

Adjust the fert water ph after mixing to about 6.

When watering, 20% of what you apply should pour out the bottom drain holes.

CLF=constant liquid feed...feed with everywatering

That was the most detailed and specific answer I've ever received on the internet. You have no idea how much I appreciate that Blackvelvet. It should be a while before she's dry enough to water but when I try this I'll definately come back with an update. Maybe I'll have a meter by then and I can test my water too.

Here's how she looks tonight. Seems to be getting better every day. The yellowing is getting worse though so you're obviously right-she needs some N.

It should be a while before she's dry enough to water but when I try this I'll definately come back with an update.

There is a horticultural expression..."Wet is wet." So if your plants need a drench of new ferts, fungicide, etc...go ahead and do what is needed. If the plant is in need, go ahead and apply it because it does not matter. You did not make it any wetter.

 

[pickledLSD]

So I could feed her tonight then? You've been extremely helpful Blackvelvet. You may have saved my plant.

"You must spread some Reputation around before giving it to Blackvelvet again."

 

[pickledLSD]

My hat is off to you Blackvelvet. You saved my little lady. This thing took a 180 degree turn after I fed her per your suggested mix. Here she is tonight.
