Last throw of the dice

[Homegrownplease]

Germainated 7 seeds just under a month ago. Had no problems for the first two weeks. Plants looked healthy and big.
I’m using coco coir pre buffed and perlite. 3by3 tent 100 w light. I did add low nutes straight away as I thought I had to but found out later I wasn’t suppose to. But the plants looked good so I thought it was ok. I was not always watering to run off as well as I read you could over water and kill the roots. But then I found out I was suppose to cos u can get a salt build up and nutrient lock out if u don’t. ( So many different opinions and I done so much research that’s where I think I’ve gone wrong). So I was feeding 5ml A and B canna and call mag for first two weeks then started seeing the yellowing leaves start to apear .My PH was always around 6 but I did suspect my meter might of been crap. I bought a TDS meter and tested my PPM run off and it was over 1500 and my PH was low about 5. So I started flushing and got my PPM to about 500 but couldn’t get my PH to 6 it was as always saying 7 but I think my PH meter was crap. Also I started adding Epsom salts to my feeds and a Foiler spray as I thought it was mag deficiency. After flushing I carried on feeding every two days but the leaves still going yellow. Ive cut a lot of leaves off as well but new ones keep coming. Ive just upped my feed to 5ml per gallon hoping it might fix it that was yesterday. I’m goner send as many pics as I can. If there’s anyone with some good knowledge on what U think the problem is and what I can do to fix it I would really appreciate some help as it’s driving me mad. I’m thinking of just giving it up as I live in a flat and I haven’t got much space. I just want healthy plants to look after. Sorry for the long post I just want to get as much info in case someone can help. Thanx for reading

I also use coco to grow and I water to get 20-30% run off everytime. I am in my 2 week of flower and (knock on wood) lol no problems this far. I hope you get it figured out.

I know you're not supposed to be able to overwater coco but would those visible roots be a sign of roots looking for oxygen, maybe they are overwatered.

Good luck with that mate thanx for a reply I just want my leaves to stop going yellow driving me nutts and my bloody wife

Good point that didn’t even cross my mind what would u suggest I do just stop watering for a few days ?

 

[AlexGrowns]

Yeah if that's it, it should fix it. And do you have a little ventilation?

I’ve got a fan going if I can sort this problem out I’m goner get a carbon filter but I don’t want to invest any more time and money unless I can sort this out as it’s been two weeks going on. I do think I had a nutrient block out as I wasn’t always watering to run off but I’ve flushed them I also had them in smaller pots but moved them yesterday to gallon pots. But I think your right they could be over watered I’m just not sure what to do with them at the moment

I’m watering in coco 8litres everyday it seems to be loving it from what I’ve read u are supposed to have 90percent saturation at all times my guess would be a slight ph problem don’t give up on em they will bounce back good luck mate.

Good luck with your grow mate. I’ve ordered a new PH pen I’m goner give it two days then run ph 6 water through them and see what the run off is PPM and PH etc then decide what to do

I just wish someone could look at the pics and day do this this is the problem but I know it’s nit that easy as over watering nutrient deficiency lockout etc over feeding all have similar symptoms so it’s so hard to diagnose I should of started with a soil mix with nutrients cos I think I fuked it with getting my ph and nutes wrong good luck mate

If it's a learning experience why not at least take one and stop watering it for a few days or more, then you'll know for sure. I could be wrong. PH pen will def be a great tool in your belt and will eliminate that being a problem.

Good idea I’ll experiment with a few I did have a PH pen but I think it was crap and it actually broke yesterday I’ll stop watering a couple flush a couple and feed nutes as well nice one mate

so you've got 7 plants and they all have different signs.
lets start over and make things easier to follow.
1- Read this thread and copy past the questions and fill the information here.
2- Let's start with one plant and diagnose each separately.
3- your humidity should be at 60/70% and either your humidifier is to close to one of the plants or you have spider mites. That would be 2nd and 3rd pic you posted in your first post
