Coco/Perlite Plants Not Growing

[ChenBentz]

I'm having some very serious issues with transitioning to Coco/Perlite.

I have set a drip system with a reservoir and I use Dutch Pro nutrients and try to his 800-1000 PPM w/hard water.

I try to water once a day, sometimes every two days and adjust the pH every time. I leave the nutrients until all the water is gone and I have to refill it.

Some plants have run-off trays and some don't. Doesn't seem to make a difference, as the water just stays inside the pots like soil. I can't tell why.

Lights are 600w at proper distance.

Temperature is kept at ~28C with good air-circulation.

The plants don't seem to die quite as easily and they NEVER wilt like they did in soil, but they just won't grow.

I have several clones that are simply dying. I'm not sure if I'm watering them too much or too little but they shouldn't be dying - I know that for sure.

If anyone could help, I would really appreciate it.

I'm considering uprooting all the plants and putting them back into soil where it's safe.

Thanks.

150 ppm. 400 Max with vegging. Don't use 900 1000 ppm till 3rd week flowering photo period. Not from 12/12.

clones in back 5 days old. Took 10 days rooted. Under 150cfl. Coco + perlite. Feed 150-200. Next week bumped to 400ppm.
These are now. Unknown bag seeds. Made one a mother she's over 3ft tall. And other 2 seeds nearly done flowering.




Veg Ph needs to be higher.6.5 6.7 etc......


5.8 once flowering. Feed morning.ph water 1hr before lights out repeat. Flush every 7 days. Pump juice next day. Every 3 weeks. Flush and dry for 5 days. *Then pump 1.8ec. Or 1000ppm. Repeat. "At 6th week. *5th week flowering add pk.13/14 etc

well you might be giving them too much water. coco will retain water. like a sponge. also make sure they getting cal/mag. i have too with tap.. i find they do better if your dry out and extra day

I hand water once a day. Drip U would need for for hydro. Wouldn't do it for coco that's why urs are yellowish flushing it out before it even drinks food

.Hey dude, take out your drippers. Drippers are ok in coco but not at the point your at.
Water them by hand until you have a bit of run off each. Lower your nutrients to a much lower level. likely your locking out at those strengths and because they are always damp the roots will be going to shit.
Take out the drippers, let them dry out considerably and then hand water until you are transplanted to bigger pots.
In coco they do like to dry out in between so always better to shut of your drippers at certain times. When coco dries it pulls in more oxygen to the roots. You will find coco far more forgiving than soil but it still doesn't want to be constantly soaking wet. If you have to use drippers adding h2o2 in small amounts to you solution a while before topping up your res will help prevent root rot.

Can that be used in coco?

Ive not used it, but if it can be added to soil it should be ok to mix in with coco, the problem would be how long before what you add runs out. I suppose it could be added on top so when you water you are feeding it. Personally I prefer to not add anything to coco like that but if you are sure you have a cal or mag issue and don't have any other option then its better than nothing.

Id bite the bullet I wouldn't wanna add anything to coco either lol

Can you not get some cal/mag from Australia? I would of thought theres plenty of legit uses for it where you are, seems your water has everything filtered out so it wouldn't look dodgy importing some.

Me and my partner are dying to buy seeds online. But one guy got arrested and charged for seeds.online. my grow shop guy said wait till Christmas and order from uk. To much mail. So we waiting till then. But all is good we got bag seeds growing good.

Well good luck, if you do end up ordering from UK pick n mix seeds are reliable and fast delivery. You can buy singles or if you buy 5s or 10s they come in the original seedbanks packaging. I have seen a few customs programs on OZ and NZ they really don't like seeds! But mail order at xmas seems like a good idea.
