Problem

I'm in the middle of week four flower with two Nemesis plants. 5 weeks of veg, toped for 4 and lsted. There is about 23-25 tops between the two. Around week 4 or 5 I started noticing the lower fan leaves yellowing and falling off slowly. I was giving it veg nutes half strength 8-0-0. They are still falling off.

At first I thought it was because they were just so fdamn bushy they just were not getting light. But its getting to the point were its moving up, but they are still very bushy and look perfect in every way except for this. I think about how much has fallen off and if it was all still there it would be crazy how thick it would be so I'm thinking this might be normal? Ph round 6.5. Sorry, no pics, posting from a stupid phone lol.

Thanks for any help

8-0-0 npk for veg, this is the problem. During veg they need a full npk ratio similar to this: 3-1-2. But you are in flower and now you need to switch to a bloom npk ratio: 2-3-1. Your plants are lacking basic nutrients that are needed for your plant to perform. Get your npk ratios on track and your plants will do the right thing for you. luck

Thanks for the input, its appricated. I thought maybe that had something to do with it two but I have been using a 7-14-9 shultz bloom fert since flowering began every other watering and recently got it up to full strength. Sorry, forgot to include that. I've also been using 2 tbsp of mollasses per gallon every watering since flowering began.

After doing some reading I've pretty much come to the conclusion that I was probably not giving strong enough doses of nutes in veg/ week 4 this sort of thing happens plus bloom nutes are low on n anyways.

One thing I've been wondering and not seen it discused anywhere, when you use a moisture meter do you wait until its in the red or sort of close to being in the red? I think I might be under watering too becuae I let it get almost red but I've been noticing the top layer is dry as hell when I water.

You may be underwatering, but doubtful. These plants like to work to quench themselves. If you are letting you soil dry between waterings you are doing the right thing. If your temps are good in the space then the soil (depending on how big your pots are) will be dry within 3-4 days after watering. You want to see some run off when you water, this lets you know that all the soil is getting wet. As an example: I use 3 gallon containers and water only once every 7-9 days and feed about every other watering, in my case less is more for the plants. Keep us posted and hope this helps.

I think the pots are 1 gallon. They are 10'' around the top. I usally water every couple of days, I don't think its under watering either.

I am still having a major yellowing issue and I still can't post freaking picture and that is very frustrating.

Picture 2 plants doing the exact same thing. Each is a foot tall and has been topped for 4, and lstd with about 10 tpos a piece.
All fan leaves have yellowed and fallren off. All other growth is green more or less and the tops growing under neath is very green. ( I figurerd I would harvest the top and then let the undergrowth tops grow out afterwards like some here have said they do)

The only thing I can think of is that the plant knows what its doing and is getting rid of those leaves to 1. Get more light underneath and 2. There are so many bud leaves that it dosnt need them anymore. But I'm still worried.

Since I have roughly 4-6 weeks left I plan on adding some more 8-0-0 to my next watering that will also include the bloom fert which apparently has not got much n. I will add this half strength unless someone has a better idea. I watered with plain water about 2 days ago.

Get some hammerhead pk 9-18 agreesive flower boost

Thanks, but I'm not having flowering issues. In fact flowering is going very well. Almost every top has developed into 4 inch colas and at least 4-8 of them I'm hoping will be foot long colas when its done. As long as I don't nute burn them really bad or let the n deficiency get out of hand I think its going to be an awesome first grow.

Have you checked your ph?

If your ph is within normal ranges for soil growing (6.5-7.0) then feeding them your 8-0-0 and the bloom booster should turn them around. Your 8-0-0 food is just nitrogen and then when you add the bloom to your mix you should have a full npk value to feed your plant.

I know we have already talked about watering, but, do you let them go 3-5 days between waterings?

Have you given your plants a flush since they started growing?

If not this may be a good time to rinse and clean the soil of old unused ferts that could be standing. If you decide to flush, use plain water and run at least 3 gallons through your pot/soil, and let sit for a couple of hours. Then water but this time add your nutrient mix at 1/2 dose.


I wish you could post pics because this would really help with a more precise diagnoses. Sure you can't get pics?? Camera phone????

Hope this helps. luck

If the plant still looks good then i would not worry so much but i would change my feed.During the veg cycle the plant still need a good n.p.k input like the other guys are saying i would change feed.You want to make sure that you have a nice feed going in to the plant so when it come's to flowering the shock of the change of nutrients won't result in burns.But a nice looking bushy plant is what every cannabis grower should be aiming for because this means that the internodes are nice and tight.Thus giveing you more buds when the internodes join forces.

I've been making sure the ph is 6.5 going in and the one time I checked the run off it was the same as going in. I've not flushed them but I think I will after the next watering which will be full of ferts lol. I water ever 3-5 days depending on what my meter says, I let it get in the red or right before and water

I do have pics on my phone and I have been using my phone to access the internt but when I try to post the section says disabled.

Thanks for all your help

Cool, sounds good. I was planning on getting some good ferts next grow, there is so much out there its hard to figure out what's good to use. I just got the walmart/lowes stuff my first grow so I could see what changes I make makes the biggest diffrence I guess.

Anybody got recomendations that you've noticed helped your plants out when it comes to ferts? I'm thinking about a veg/bloom combo or something that works well through out the grow

Yellowing, spotty leaves with a thin, paperlike texture that starts at the bottom and works its way up is textbook N deficiency. Adding fast acting N will save the undamaged leaves, but since you're this far into flowering it doesn't seem worth it. If you're concerned about N def for your next grow, try blood meal. It's slow acting and gives good results. Just sprinkle some on the top of the soil once you've transplanted to your final pots and the plants are in veg. The N will slowly be released over time and will keep your plants happy throughout the grow. Plus its easy to get at home depot or the like, and is super cheap.

As far as ferts go, ask any 10 growers and you'll get 10 different answers. I just say use high N ferts in veg, high P ferts in bloom, and you should be okay. Any decent brand (Advanced, Foxfarm, Canna, etc) should give good results...and it seems like you're doing okay with pretty cheap stuff.
