Underwater? Deficiency? Other? Vegging plant yellowing around vein

[Ns1]

Hi guys, banana x og clones, planted in 65% FF soil, 35% perlite, going to add some lime soon, sitting under 3 43watt daylight cfl's

About 1 week after receiving them


This first plant there's definately something going on here






And this second one is...overwatered?






Any feedback would be great. Thanks guys!

Anyone? =*( Her condition is rapidly deteriorating

yes i think there both over watered but you better get an experts advice, though if it were me id think they look overwater. Do you think you over watered? Hang in there someone will give some advice soon hopefully. They dont need much water too earlier,
mostly flowering..depends on what strain but most are normally fine. just wet them enough to soak the roots...thats all. Its better to under water than over water..like..they dont mind too much being thirsty,but always make sure the soils light-damn not too dam.Thats me though..someone else should hav some info!!

Good Luck!!

Don't know if I'm too late or not but first thing I'd do is flush the shit out of them. pH the water to 6.0 and pour - drizzle really - about twice or three times the amount of water through them as the pot size - i.e. 2 gal pots = 4 gals water. Then let em go for a few days to lose some of the water content. Then start slowly back with the nutrients, ec 0.5 1st watering, ec 0.75 second, and so on up to about ec 1.25. Hold that for a few waterings and see what's up. Likely you've got a salt build up, or pH caused a deficiency. Not sure though. If it is, the flush should get you back on track most likely.

If you don't have an ec meter and can afford one, get it. I swore I'd never get one because I was sure the little "drops in the specimen bottle" kit I was using was good enough. Not so! My pH was close to 8.0 and not the 6.0 I thought.

What size pots?
What kind of water you using?
What nutrients are you giving?
How much nutes you giving?
How often you watering?
How much water are you giving?
What's the pH of the water?

More info needed if you want quick help. It takes time to get a response as you can see, so tell it all so one response can help more. I'm not an expert but there are some here and I might be able to help too.

I grow in coco, so the plant doesn't get anything I don't put into the water and coco can't be over watered. Lots easier than soil, in my opinion. If you're using coco, you're one step ahead and will be easier to fix.

Let us know.

What size pots?
-4", sorry don't know other than that
What kind of water you using?
- bottled arrowhead water
What nutrients are you giving?
-1/4th strength foxfarm growbig
How much nutes you giving?
-see above
How often you watering?
-once every 2-3 days
How much water are you giving?
-2 waterings spaced 1 hour apart, not enough to have it drip out of the drain holes
What's the pH of the water?
-according to teh net, around 6.

Sigh; the unfortunate thing is if these die then I won't have the resources to start again for a few months. Oh well, if that happens I'll just come back next time bigger and badder.

Ok, pot size is ok for this stage of growth but your going to need to repot before too long AFTER you get this prob fixed. Water source should be ok but don't know for sure what's in that brand of water. Probably alright though. Your probably ok on nutrient strength, I normally grow from seed though and when growing from seed, we normally go easy on the nutes till we have enough root growth to handle the load.

You need to get yourself a pH/ec meter if you're really serious about growing. Hanna makes a great one and a lot of growers, including me have use this brand. Any time you add nutrients to your water it will change the pH and plants are finicky about their pH. Ideal would be probably 5.8-6.2. If your mixing your nutes ahead of time, water/nute pH changes over time and normally rises. At higher pH numbers that plant can't absorb some of the nutrients you're giving.

Watering frequency may be ok, don't know. Ideally, I think in soil you want to keep the soil moist but not too moist. Stick your finger down into the soil mix and after you pull it out, blow on it. If it's cool then you've got at least some moisture in there. I grow in coco so my plants always get enough o2 at root level, but with soil you can get into a situation where the soil gets so saturated with water that the roots can't breath and they rot.

If there's any way you can, I'd jerk them out of what you've got them in and put them in some coco. If they're going downhill quickly and you can't get your hands on some coco quickly, get another medium like rockwool, peat, styrofoam, or something like those that breathes and will allow your plant to start recovering. Get some coco on the way to you and use it to continue the grow. I use Canna coco and you can use it without flushing the salt out of it. Other brands of coco, from what I understand need to be flushed with Cal Mag several times (use warm or hot water to flush) to get the salt out of the coco. Once you have them in an inert medium like one of the ones I just mentioned, water using very weak nutes until the plants regain their footing.

Hope this helped, I'm by no means an expert grower and almost any grower around here has more experience than I do but I've had to cure plant ailments in my grow and these things are what saved mine.

Visit the infirmary and ask an expert. From the way your leaves look I would think a nitrogen problem. Weird pattern though, so I don't know. Get some closeups of the leaves and plants and post them along with your questions. Someone will be able to help. Doing the above though, by re potting into a breathable medium will buy you some time I think.

Anyone else here have any better suggestions for Ns1??? Needs some help QUICK!
