Deficiency and assimetric development

ChefdexV2
ChefdexV2started grow question a year ago
My girls seem to have a deficiency, strangely enough, the gal with the most signs of deficiency is doing the best in bud production. Any ideas on what is going on here and what is the cause of the deficiency? There is also some purple on the stem

Just going to jump back in here and disagree with my growmie who's telling you to use calmag every time you give your ladies water or nutes... please don't! Too much calmag can actually CAUSE a deficiency of other vital nutrients ... it should only be used once a week maximum and since they're in flower, I'm sure you're giving them either water or nutes more than once a week... https://weedmania420.com/growing/can-you-overfeed-calmag-signs-symptoms-and-solutions/

Firstoff, thank all you guys for commenting and helping me out. I do really appreciate it! I'll try to respond to all commenters at once: @gREEn7o0 I don't water in between feeds, I feed the gals every other day. That's it. I tried giving them regular water in between feeds but they start transpiring heavy when i do so. The RH in my grow space is quite high and that might be an issue. The outside of the top part of the soil dries out but the core stays moist. I try to take good care of the microbiome since I grow organic. Hence I also don't water to runoff, I water just enough so that there might be a little drip of water coming out of the bottom of my pot. But i take great care in not over-watering, again, because of the preservation of the microbiome. I do supplement with CalMag and speculated that the molasses blend i use had a too high Kalium concentration. Kalium saturation can lockout Calcium and magnesium, so I backed away from the molasses blend, which seemed to help with the rust spots a little. Now that I start to introduce the flowering nutrient line, the spots come back a little, so It might be a lockout. I am very cautious of over watering and I'm not too fond of rinsing the soil, since all my nutrients are organic and i don't want to rinse them out. @Ctrellis90 That is a primo piece of wisdom you bestowed there! I will try to fine-tune the nutrients to the individual pheno but that does seem a little hard man :p Still, I'll have to experiment a little... @CreepySteve The redness is a little in the pistolas on the top, but also on the leaf stems. I didn't find it stange looking but someone mentioned that it could be a bad sign. Eventhough i don't really know what it mean! My current nutrient setup has more P in it, so i hope that helps? I'll grab one of the girls and make some picutres under sunlight for next weeks journal, that may help? @Organoman I've seen this cultivar do great under 24/0... I get what you're saying, I would love to give them some rest, and save some energy bill money... But i need to keep the light running to stabilise my environment. I have added a P/K booster this week :) @GrowingGranny Thank you for your comment, first about the week, it inspired me to check on the webbrower version of my diarie and i found out none of the photo's i uploaded in week 4-5-6 actually saved😭 So now i'll update the diarie from my brower. Anyway, I'll try the macrodosing of CalMag once a week, instead of every feed. I'm afraid I can't flush out the soil... Since it's an organic grow I'll destroy the microbiome I've created. I've picked the BioCanna line because of it's bioavailability in the hopes i wouldn't have to water too much, since humidity is quite the issue in my small little growing space. Would you recommend feeding less? So maybe plain water once a week? @Wrongholn519 Thank you for the comment growmie! I like the idea of backing off a bit with the calmag from GrowingGranny, so i'm gonne run with that. Thank you for the help either way :) Again, thank you all for commenting and thinking with my, Bless you all!

So a few things I noticed and have questions about: You said you are feeding every other day? Are you watering in between feeds, or just pumping full of nutes. I think I saw somewhere that nute line is feed 1x a week? Is your soil drying out in between waterings/feeds? Next you said plant doing the best is having the worst issue which means its likely a deficiency of some sort. I'm wondering if it is some kind of lockout from salt build up from always feeding, or if it is a magnesium issue since you seem to be in early flower (they seem to have a high demand for cal and mag early flower under LED for me) and in one of the pics I noticed some rusty spotting on larger leaves which I'm assuming were fan leaves which means its mobile, but the rest of plant is yellowing as well, which makes me think calcium was in short supply too.. Sorry thinking out loud here.. I think you said mid 6s for ph which should be fine. Ts 1000, so that should be fine too, and it seems to be causing whole plant not just top, so likely not excess light/too close.. I'm leaning towards calcium and magnesium shortage. Are you watering to runoff every feed?

Welcome to the world of pheno hunting my friend. Unfortunately you can have ten twenty plants all the same strain, given all the same feed and growing conditions and still...they will grow differently. Each pheno is going to thrive best at different conditions and it's up to us as the grower to determine what those conditions are. That being said, I recommend some fine tweeking on your feed for each of your plants instead of giving them the same doses. Find what works best for each pheno. Now, even when all conditions are met, you can still end up with a wonky looking plant or a premo cultivar. It's all on the pheno and the grower. Hope this helps.

the leaves look fairly lush in the photo not under grow lights, so i don't think they are underfed in a major way... some spots -- if not accompanied by interveinal chlorosis could be Ca related... if accomanied by interveinal chlorosis, then Mg is a possibility. red petioles are common under led... if relegated to the top, it's easy to dismiss, but if everywhere, probably means you need more P. red in stems woul dneed more sulful. stems vs petioles (leaf 'stems') is an important disctinction. This can also just happen... so, if you do choose to boost P, don't be afriad to back off at first since of an issue. You can get used to your grow lights and what the leaves look like in photos under them, but others won't have that familiarity and even that isn't enough in some cases to properly diagnose a plant... your eyes do better in RL, but still may need to remove a leaf and look under normal lighting to get a better idea of what's going on anytime an issue pops up..

Exhaustion from too much light..........go to 18/6 and give them the sleep that they NEED. Adding a P/K booster to your fertilizer line up would also help them.

I would hit them with some CalMag. At this point in the grow your girls want calcium to build strong cell walls and encourage photosynthesis. Calmag also contains calcium nitrate which is readily available for your plants and help get them back on track. Use calmag at full strength every time you water, even when you add nutrients

This is a little tough to figure out here... (and btw, they are in flower now so change up the "type" of week in your diary from vegetative to flowering)... anyway, I can't find information on the NPK of the nutes you're giving her but it seems as though you've done the right thing - i.e., backing off on the nitrogen and increasing the phosphorus and potassium... and your pH is spot on... so I'm left with looking at how much water they're getting on average per day... and I'm thinking you may have got a lockout going on from built up nutes and salts in the soil - i.e., I don't think you're watering enough when you give her plain water. Now, if you are watering so that you get a runoff every time, then I'm wrong... but if you don't do that, I think you're going to have to flush the soil to get rid of those built up nutes and salts. That means 3x the pot volume (in your case, about 45L) of pH'd water run through each pot... in the last liter of water, add 1/2 strength nutes and then let them dry out completely before giving them another drink of plain water... After that, you can resume your nutes at full strength. You might also want to try to get a PK booster as this is what the plants are most needing during flower. And always practice a routine of water/feed/water/feed - and when just watering, make sure you get some runoff that you then throw away so they're not sitting in water all the time. Good luck..
