Is this a Hermie? Also, yellowing leaves... and gnats...

I have been flowering since 4/1 and have noticed some leaves yellowing. Doesnt look like burn, just a gradual yellowing. I thought it was not enough light so I LSTd to get light going down through out and still having the problem. I then bumped up the N with some veg nutes and its still going on, but with some burn... I backed off on all nutes for a few days now. I am using an organic buds and bloom fertilizer that is 7-15-7 and is made of castings and other things from a local shop. Thinking it may be over watering, I dropped the watering down and still losing the green.... I am using 8 23w 2700k CFLs and temps range from 75-82.

I also noticed some strange bulbs on my plant. not sure if theyre just pistils or a sign of hermie. I am not sure what the "footballs" look like but I included a pic.

I also have fungus gnats that hitchhiked inside on some basil seedlings. but I ordered some pyrethin spray for them.

This is my first grow so any help is appreciated.

Leaves starting to yellow during flowering is not always a bad hing. The plant is coming towards the end of it's life and with less nitrogen required at this stage it's natural. Typically they will begin to drop off by their own accord. Give thematic helping hand but don't pull them off with force. Some pictures may help us get a better idea of the yellowing if you feel this is not the case.

The gnats on the other hand lay their eggs in the soil. A good way of getting rid of them is to pour an inch of White sand in the top of your pots. This will suffocate the larvae. A saucer of cider in the bottom of your unit will attract and drown all of the adults.

I use a 2-8-3.5 feed during flowering. You shouldn't be dozing them up with N at this stage

Thanks, I have heard different things about leaves yellowing. Its lights off right now but in a few hours I will post a picture. I have a 40 lb bag of play sand and I think I will put some of that on it. I also have fly strips and theyre helping.

Ive also looked at some other pics and my pistils may just be pistils after all but if someone will take a look at the pic I posted previously.

here are a couple more pics of the leaf color I am talking about. as well as the hopefully pure female organ. I think there is some burn here that wasnt there before I started adding more nutes to see if that would correct it.

Those look like female parts to me.

Also, can you post a pic of the whole plant so we can see where and how much yellowing is going on?

Also, you shouldn't spray poisons on your plant during the flowering phase. Fungus gnats can be controlled by methods other than pyrethrins and they aren't too big of a threat to your plant unless you have a LOT of them or small seedlings/clones. Do what hiroshima said for the gnats, and also you can get some of the yellow sticky card traps. The gnats are attracted to the bright yellow so you'll trap a lot of adults that way, hopefully before they can lay their eggs.

And I don't know if play sand is the same as the White sand that hiroshima was talking about. You may not want to put play sand in your plants. It might not kill the gnat larvae like the White sand and it might do something bad to your pH. It might not hurt it at all, I don't know, but you might want to wait on some confirmation from someone who knows better before you do it.

a few more pics. I am concerned more now about the little rust colored spots. I went to pick up some proper nutes for flower as I dont really trust my mix, but the local shop was all out of tiger bloom.

after reading through my BUDS for less book, the yellowing seems to be natural.

could be lock out. but def looks like a cal-mag def. Your bloom foods may not have had enough if any calcium or magnesium in it, but if your not even a month into flowering, and there is an abundant amout of yellowing and spotting. You could've used your bloom food too early. or you could have lockout. I think you need a flush. Im no expert. just my opinion

Thanks for the tip. I will look more into cal mag def. I used fox farms for veg. going to pick up their tiger bloom asap.

I try to flush a little at least once a week. I am afraid it could be lock out but really dont know. And really nervous about repotting at this stage. I leave for a month in just under a month and losing a week to shock is something I would like to avoid.

i have the same exact looking thing on my sativas.
that lil sack with two red pistils about 4 weeks in i think your good its not a hermie.

doing a little more research looks like it may be lockout because of my hard water. will now be filtering water through a brita filter from now on. making a new tea for nutes til I can get some tiger bloom. added a teaspoon of my dry mix and about half a teaspoon of grow big to try and bump up my cal/mag(per half gallon). will try and flush tonight, then give a dose of nutes tomorrow.

What is the pH of your soil and water? Calcium and Magnesium both start to lock out at pH 6.4 and lower. If you've been watering with low pH water, your soil probably has a buildup of acid salts and needs a good flush to clear it out. You need to use 3 gallons of water per 1 gallon of soil you use to flush properly. So if you have a 3 gallon pot, you need to run 9 gallons of water through it.

Hard water tends to have a high pH, but when you add ferts it lowers it a lot, which is why you need to make sure you measure it and adjust accordingly.

Even if you're giving it Cal/Mag, it won't be able to absorb any if the pH is off too much.

I did a little flush. My water ph was kind of high. around 7. a little lower when I use my brita. I use 8 in pots so I am not sure how much water to use. I probably used just double the water. the sand gets kicked around and I have to pour very slowly so its a hassle. I am including some more pics of tips burning and one of a leaf with yellowing and burning. I am getting my tiger bloom in soon, should that help with my deficiency?

Yes the Tiger Bloom has Calcium & Magnesium in it which will help once your plants are at the right pH to absorb it. From what I read online about the Grow Big it does not have any Calcium or Magnesium in it so it won't help with those two particular nutrients. With 8 inch pots I would use like 2-3 gallons to flush, I know it is a pain for me as well but your plants will be much better off.

Once your pH is 6.5 - 6.8 or so, and you add the Tiger Bloom it will fix the Cal/Mag deficiency. However, you will continue to see damage even after you fix the problem for a little while, and you are going to get some leaves dying, so don't freak out. As long as your new growth is not affected you don't need to worry.

I was holding off on the flush, but started seeing some more spots. Did the flush last night. used about 2 gallons. hopefully this helps. I did notice some gnat fly larvae floating up through the sand. Should I put some more in? Or I also have some organic pyrethrin I can mix with the watering.

I don't know about mixing pyrethrins with your water, I've always only used it as a foliar spray, but not during flowering. It's good that the flush washed out so many larvae though, so you can remove them. I would look for them every time you water to see if more float up and can be removed. The more you can kill without using poisons, the better.

You can also put a peeled potato slice on the top of the soil, and the larvae will crawl up to feed on it. Just pick it up and look under it every once in a while, and remove any larvae that you see. This might not work if you have the sand on them already, but you could give it a try.

thanks man. I did a light mix of pyrethrin and water, just enough to soak in about an inch. I put more sand on it and the adults numbers have dropped. ill try the potato thing as well.
