health Yellowing on top leaves starting...what's wrong?

B

ballgum

I have 6 plants total (habs, bhut, FT scorpion, BT scorpion). The only 2 that are starting to show yellowing on the tops are the scorpions! Do scorpions require any special needs for feeding? Because my other plants are all green, just the scorpion's are starting to yellow....

I know it's not overwatering. I only water when they are completely dry and showing signs they need water.

They are in straight promix HP and I feed using Dyna Gro.

My last feeding was with: 4ml bloom, 2ml grow, 3ml protek, and 2ml calmag.

I'm wondering if the yellowing is due to mag deficiency? I also only water with ph'ed water, so I know that's not the issue...

Any thoughts?

+1 on the calcium....you might also wanna add a sprinke of epson salt while your at it.

how can you tell its calcium deficient? the yellowing? or the bumps?

i went ahead and watered them a gallon each plant... i gave the yellowing plants each 10ml calmag and 4ml bloom...

the non-yellowing plants i gave 7ml calmag and 4ml bloom.
 
i agree, it looks like classic calcium deficiency. you might try blasting all your fertilizer info into something like the saltmix.xls spreadsheet or this website to see exactly where you are.
i run a DIY promix and water with the resh pepper formula at 2 EC without problems; i wouldnt sweat feeding them more.

btw you feed protekt? have you seen any improvement from adding silicates?
 
I had plants do that many times, 1 TBSP Epsom Salt on a gallon of water is your answer. just add the water till it comes out from the bottom and the soil stays moist. They get so green with that, Its high in nitrogen.
 
the yellow leaves will probably stay yellow. the new leaf growth will be green. i have 2 baby bhuts that went yellow. after i have them some salt and calcium, they stayed yellow but the new leaves were beautiful green.

I added the calmag earlier today and they are still yellow...So we'll see tomorrow.

Sometimes it is better absorbed through the leaves. It might help to mix up a foliar spray. Calcium moves slowly in plant tissue. It will also take at least a day to see a real difference.

Edit: With promix and with fabric containers you might need to water more often. The roots will still get plenty of O2 and they'll be less stressed. Complete drying out cycles probably make more sense with soil and much heavier mixes.

so it is the yellow leaves that are telling you guys its a calcium deficiency?? I'm still learning here... so I guess my question it, how do you know its a calcium deficiency instead of some other deficiency ?? like nitrogen or something else?

fyi... they still look the same today. :( I guess it takes a little time. I may make a folier spray out of the calmag and folier feed them tonight? If this ia good idea, then how much calmag should I dilute in the water? The bottle I have says 5ml/per gallon for soil water feeding
 
when a plant is calcium deficient, the margins tend grow at a slower rate than that of midrib or center portion of the leaf. thats why you tend to see distortion with calcium.

we can infer its not nitrogen because nitrogen is mobile and begins at the bottom of the plant and moves towards the top. we can infer it is not magnesium because mag also shows up on older leaves first, it also tends to show up in the leaf margins first as interveinal chlorosis.

this imo is the best flowchart for deficiency symptopms. keep in mind some of these symptoms can also be caused by PH etc.

i dont think anyone here is claiming its 100% calcium deficiency, or at least i am not. it just seems to strongly resemble it.

IMO you should take stock of what exactly you are giving the plants using that website i linked. your fertilizer bottles should have all the necessary information. use saltmix.xls or that website i linked.

The bumpy leaves shows a Calcium deficiency. It is much easier to get Calcium into plants using foliar sprays. You can either make your own with eggshells (Search the site, it involves charring and dissolving I haven't made my own yet so I'm not 100% on the recipe). I use Calcium Chloride at the moment because it's all I could find locally and bought it before I saw the recipe on this site. Once it's gone I'll be making my own to avoid the chloride part. If you buy the Calcium Chloride from a big box place like depot or Lowe's, don't mix as much in as it tells you to. I think it says 2tbs a gallon. It burned some of my plants pretty bad, so I use it at half strength. Some plants are still a little sensitive to it.

I would go get one of the Gallon pump sprayers and give them Calcium that way. Also feed Mag that way as well. Take the full gallon sprayer and dissolve 1tbs epsom salts in it along with one crushed up 325mg aspirin. Let it all dissolve and hit them with that every 2 weeks or so. You'll see definite results from that alone.

I'm still learning as well, but the biggest lesson I've learned is not to go nutrient crazy on them. Peppers don't take much, and don't like a lot. Go easy on them and they'll be happy.

calcium nitrate is another much more common source for calcium, i would be suprised if you could not find it locally. i make my own fertilizer so i bought 5lbs of yara at a local place for like 7 bucks

That is the best nutrient deficiency chart I've seen to date. Thanks for sharing QQ!!!

Damned skippy it is. That should be a sticky at the top of the grow forum. That along with several real life pictures of the different deficiencies in a nice clean sticky would be an amazing resource.
 
hmm...leaves are still bumpy. Maybe the calmag hasn't hit them yet? I fed using water (not folier).

Also, I noticed you said calcium deficient is the bumps...but what about the yellowing of newer leaves?? I've checked the flow chart, but still dont quit follow what could be causing it...It is still only the 2 scorpions that are yellow!!!

I was thinking of watering next watering using only ph'ed water with epsom salt...i havent used that in awhile? (although the calmag has mag in it)... What else could be wrong?
