New growth pale/yellow, getting worse. Coco/perlite

Coco without an autofeed is a bitch. Can't wait to get a bigger veg area and put it on auto feed. It took a long time for me to figure out how hand watered coco plants act.

The main issue is that when they get locked out, they look like they are overwatered because they refuse nutrients and suck up water faster. Soil plants usually show burn instead of doing this.

I don't think these guys are trying to steer you wrong. I suggest letting the cups dry out and checking the new growth, if the new growth is back green, its because of the issue I stated above.

coco seems to difficult as it has no nutrients and growers usually get the feeding wrong. coco traps water and nutrients. I would think you have to go easy on those ferts, but then I've never used coco. it just seems logical is all. Compare it to DWC which has a lot of water, the dilution is going to be high if you don't use 800-1000 ppm. In coco, I'm guessing you don't use so much, but that's just a guess.

In my experience, coco does not need a lot of nutrients, it stays in the coco and is hard to flush out. Unless you are on an autofeed from the bottom (the plant learns how its fed and adjusts accordingly), the plants will lock up quick.

Edit: Try to get away from nutrients that are really salty and leave build up. Go for a concentrated synthetic nutrient (I use Heavy 16) that doesn't build residue so easy. Advanced nutrients will lock up coco plants fast, its why they made new formulas for coco.

I do water to Runoff every time, plenty of it. Don't need to water daily though it is optimal. As long as it don't dry out I can feed twice a week no problem.

You started this thread asking for advice because your plants have a problem and you've been given some good advice by Boatguy but you choose to ignore it because you know better. Apparently what you're doing isn't working pal. Why ask for help and ignore it when given?

It's no wonder your having problems......you're treating it like soil.
Feed every day to substantial run off. EVERY DAY.
Never plain water.....ever.
Never let it dry out.

I feed every other day, but my plants are sitting in trays at the moment, can't really drain to waste. If I feed them every day in trays I run into issues the OP has because they are sitting in a tray of water.

I feel your frustration, its really annoying when you try to help some one and they think their problem will be fixed if they win an argument with you, the guy trying to help. They project the problem onto you and make you the enemy. I think its called "strawman" tactics, but I could be wrong. Its a self preservation technique the mind does. Its easier than admitting a flaw or taking a hit to the ego.

Boatguy says that because you're over doing it on the nutrients. You have some leaf tips that are yellow/brown and dying, which is typical of over fertilizing when the leaves are also kind of a dark green color.
Are you sure that Hydroguard is necessary?

Yes think so too. I'm going to try just 25% strength to see how they respond next feed.

No it's prob not and when I'm done with the bottle I'm going sterile using hth shock pool.

I'm not ignoring anything, nor trying to defend my ego lol. Im trying to say that me not watering everyday is not the problem, so we can move on with other ideas.

I do not know what the problem is but leaning on poor drainage atm. If it is poor drainage I would really drown them if I do it daily? I'm not gonna just jump on the first advice without making sure it will not make things worse.

Mine are hempy, they are always in a bit of water.

Don't project urself on me please. The irony in that comment blows me away. Do u ever think/do that? Cause it makes absolutely no sense at all. Its about moving on not "strawman tactics"? But u do u

Is this for real? Finally some info I've never heard. If it checks out and they don't get worse this is the plan.

New growth is very stiff and thick. Older with normal colour are more papery.
 
I was pointing out human behavior, so yes, I do those same behaviors. It probably came across as harsh or against you personally.

A man judges his value on the responsibilities he handles, men without them ruin themselves. When some one tells us we have been handling our responsibilities wrong, we get defensive. Its nothing against you, its a natural reflex.

We are so used to running into people that need help, but refuse to admit wrongs, that we think everyone is like that. Its getting as common as a flushing debate. My previous claim makes perfect sense or you wouldn't say that I also do it.

Your medium is oversaturated or locked out. Try draining to waste or getting rid of the runoff so it doesn't sit in it and soak back up the salts. It will probably get rid of both issues doing this. Coco can hold a lot of water but it can still get over watered.

Best of luck to you. I talk from my experiences, it may not apply to your situation, but its a good start.

When talking responsibility and expectation yes, what u say will easily occur. But in a growing forum, stating myself as a noob that screws up alot, looking for new knowledge - not so much.
Ofc I will react to someone writing such belittling assumptions, cause its ridiculous. So I made my own based on urs.
If u read my comments do I come across like that? Only because I didn't agree that watering daily is necessary? Were simply trying to say there is more than one way, u CAN water less frequently without problems occuring - and move on as I knew the problem lies elsewhere.

Think ur right. Everytime I fed them I did pour it so fast it went to the rim and medium. Started floating for a second or two. Bet this made it more compact and is causing poor drainage. Also a factor, didn't bother filling perlite in bottom like I do on my big hempys. Yes 50% nute strength might be a little too much on those small plants.

Plan is to let them dry up a bit and lower nutes on next feed. I'll tilt the cups to empty the reservoir for now as suggested. Maybe add more holes if that doesn't cut it. If they get worse, I will flush them with lower nutes

Another question if u don't mind. Can any of these symptoms be caused by light to close? I know normally it don't look like this but can it?

It started couple days ago and is looking worse everyday. Clones with roots, topped.

Fed them with 50% a+b and 25% calmag and 100% hydroguard. Lots and lots of Runoff. PH 5.8.
30/70 coco perlite.

Thoughts? What is causing this?

This is exactly what my girls looked like when I had my lights cranked too high. It's hard to say for sure, since light/heat stress and fert issues look really similar sometimes. Good luck!

I'll give them some more time before I change the height cause they seem a little better today. I'll keep this in mind though.
