New Grower New grower here, a few issues

[Stonedlikeme]

So...I have some babies that are about 4 weeks old. I'm growing in a hydro setup using canna nutes. I have been playing cautious so i've been watering manually, and perhaps too infrequently. First grow..I just put them on a 4 hr timer today.

Anywho...I have had some paling, and some yellow spots on the leaves. I don't believe it is due to too many nutes as I was being cautious, but I'm a total noob and would love some feedback. When I first started noticing this about a week ago I started feeding more, and it seems to me that the babies are generally improving, but I do still see yellow, and some new spots here and there. They definitely are continuing to explode in growth. My ph has been 5.8-6.2. I've just kind of been following the canna nute guide, more or less. i eased them in and i have them at full strength for veg I phase right now. Switching to veg II tomorrow.

I have attached two pictures, one from the 26th, and one from the 28th. To me it seems to be progressing, but, like i said...Noob..

I'm not sure if the attachments will be resized to the point that it's not possible to clearly make out what i'm talking about. If so, I can send a link via PM.

FYI, the strain is biodiesel mass from advanced. If you've had it, how was the smoke?

Cheers =D

update

Since no one has replied yet I took another pic of the worst leaf of the bunch. maybe that will help someone point me in the right direction.

Most of the plants have a leaf or two that has some spotting, but this one in particular continues to get worse. Any advice is greatly appreciated.

Hey there. Sorry no one has picked up on this yet. First off I will say that overall, you're doing rather well. So think about that. To me they look a little hungry. Not certain on the spots, but they aren't terrible and we'll suss it out either way. :check:

Second, I am no Hydro guy, but I know a few things.

What light are you using?
What are your temps and humidity?

You say you're watering manually. So is there no water in the reservoir with an airstone?

:smokebuds:

EDIT: Or is that flood and drain? Looks like it after looking again. If so, then I am not certain of that schedule. I'll get someone in here.

Don't be afraid to pull a couple of those girls out.... With my limited hydro experience (1 run) I would say feed those girls, you have to provide everything they need in hydro vs soil.
As far as pulling a few of them, I had a similar setup where I had six girls using the same res, I ended up pulling 3 of them that weren't acting right. Not every bean is created equal
With all that said I think your girls look real good bud, feed them and you will be rewarded :smokebuds:

Yup, I was gonna say that too. It'll be crowded in there anyways when they take off.

What's your water PPM do you know the quality of your water? Canna nutes are made for hard water, donno if you knew that or not - they don't work as well in soft water and need to have CalMag supplemented to them. In Hydro, you start feeding as soon you have a sprout. Usually 15-25% STR recommended max dosage, or if there's a "clone dosage" half of that.

That's looking like mid-stage Cal-Mag and can get worse by bloom, I've never run a flood to drain system but I've run RDWC, Hempy and I got half way through a NFT grow.. My experience is limited, but I do know a bit.

Hola,

Thanks for the feedback so far everyone, It's nice to hear that they aren't doing horribly from others =D As for the questions asked thus far, they're currently under a 400 MH light. I spose i'll be switching to the HPS soon? I don't know a lot about the quality of the water, but it has a baseline ppm of 190 and a ph of like 9.8. With the nute solution (full strength veg 1 canna) the ppm is about 850 right now.

As for the crowding, I know it's a bit crowded in there, but I hate to pull one =( Would it be a bad idea to just let them grow out? Should I try scrog or some such?

I started 12 beans, not expecting 12 beans to pop and break ground. That's something in advance seed's favor, i spose. They are feminised and all recently started showing sex (all keepers). The temp is ranging from 73-80, typically averaging 75. The humidity, I haven't really been monitoring that. I don't have any money to invest in supplementing that right now, but that may be a problem.

So far I gather that it seems to be an mg def and I should give them some cal mag?

I will be running with advanced nutes on my next run, as I hear good things.


EDIT: This is a flood and drain system, but i have no airstone currently. Someone said I may be having problems because I didnt mix thoroughly enough between adding each type of nute to the water. I mixed thoroughly at the end, but maybe i should've mixed more in between. Thoughts?

id agree with wg. looks like they need more.cal/mag to get those leaves back to a darker shade of green. my first 3 grows.were in.dwc buckets.and I never really fully understood what was going on until.I grew in a medium. when I grew dwc, I would add cal/mag with every feeding, id also invest in some hydrozyme. enzymes break down.all the dead stuff and keeps those roots nice and healthy. also, invest in a ppmeter if you don't already amd use it, a lot until you don't need it anymore... it's good to know exactly how many parts per.million of nutes are in that feeding so you can guage how strong. your.feedings are. hydro is not.very.forgiving if you overfeed so knowing how strong as opposed to how much you're giving your plants. I used to be anal and would measure ppms after I added each thing to my water, just to see how each nute or suppliment changed the strength ofthe feed. same with ph. after a while it gets like clockwork and you can adjust your feedings quickly based on what and how much they need at that time.

hope this helps, even just a little. good luck with it amd stick with it. there's always.somene here who will try to help you

Hallo again folks,

Got some calmag plus (botanicare) today. I was hoping to get some advice on how much to mix up to resolve the deficiency? (keep in mind this is a hydro setup) My water's base ppm is about 190.

I've attached an updated pic of the worst leaf, and a new overall picture. They are still progressing nicely. Maybe I should just chop off the worst leaves?

If your water is so hard, to be honest, you won't need that botanicare cal/mag *just yet*.. sorry for recommending it. The base ppm is 190 that's pretty hard and means there's plenty of cal/mag in the water for vegetative growth but you may need it in bloom . Let's focus on the pH for now and get it fixed.. don't let it fluctuate to 6.3.. get it down to 5.6-5.8 and keep it there... pay attention to the new growth, is this problem spreading? What's your reservoir temps? Any brown slimy stuff in your res?

Calcium doesn't get absorbed too well @ 6.3... Magnesium does, but not Calcium.. dial the pH down to 5.6-5.8 and check it out.
