HYDRO Need help... new grower "Hindu Kush" fert issues

[VapeGod330]

I'm having issues with ec/ppm I add what GH chart says to add and because the calimagic at 5ml a gal. My ec is at 2.3 I'm trying to hit 1 to 1.2 ec and because the magic my ec is at 2.3 and ppm is 1.6 I have the dreaded stripes because I was only adding what GH chart said to add 1.8ml a gallon. But I noticed on the bottle it says to add 5ml a gallon and when I add that and epson salt at 1 tsp a gallon my ec/ppm is crazy high. I tried not to bother anyone but could really use some advice I've had such bad go so far and would really appreciate any help. I've lost plants due to root rot etc. ty in advance. Oh using GH 10 part light feed week two using Mars Hydro FC-8000 not using co2 5x5 grow tent, mars humidifier at 60%, light 20 in. away at 18% 160 ppfd of the 180 ppfd I can use, 24 hrs a day, DLI 13.8 of 16 feel free to ask any questions you may have. again ty!

Biggest question, ever! Do you have any pictures you can post? I will be zero help to you because I do not hydro. But pictures are super fantastic in helping diagnose things like 'dreaded stripes.'

sorry was in grow room all set ty

[VapeGod330]

double post

Can you post a pic?

That light level is really low. Are they clones? Try an 18/6 light schedule with higher PPFD of at least 350, more if in veg. and not a seedling.

If you calmag stop using epsom.

Use half recommended by the manufacturer.

Are you growing in coco? How often are you feeding them?

What is the pH input?

[VapeGod330]

Pics up now I lowered the light to 18% after all this started because plant got sick so I changed to 24 hrs to raise DLI because how low it was on 18 hrs. I added epsom because way more calcium in calimagic than magnesium. I started in coco before dwc for seedlings and didn't know I had to buffer coco. So I had to clone them due to root rot etc. I didn't want to lose them and now I think I'm way behind on cal/mag now and one deficiency led to another and now have a lot going on. Oh ph is at 5.8

[Bluey]

Can't see any pics.

So you went from coco having problems into dwc root rot cloned them back into dwc?

We need some kind of award for that.

I can't really help you with a dwc grow, I'm a coco grower predominantly.

[VapeGod330]

Yeah I used coco for seedlings then moved to dwc after roots got started.

[VapeGod330]

I used burpee tray with coco pucks the self watering burpee kit.

[VapeGod330]

I went with coco because the drainage but didn't know I had to buffer and messed me all up. But yes all clones was 100% success but I'm not cloning twice I'll buy new seeds first.

[VapeGod330]

Hope you can see them now? Sorry new and figuring out site.

[Bluey]

You have a problem with too much N which is probably just too many nutes. You can probably cut calmag if you are using it.

Additionally make sure you are running an airstone and adjust pH down to 5.8 at least every 24hrs. Check the temp of the solution when you do that. You also need an anti fungal/algal mixed into your nute solution to reduce root & nute issues.

Air Temps around 25⁰C should be good. RH not so critical at this stage but 60 to 65 would be idealish.

[Bluey]

Make sure you are using hydro specific nutes. That's is essential. Don't use organic. Don't use nutes for coco.

[VapeGod330]

I got root rot so I had to clone them all it caused a lot of issues and deficiencies one led to the next cause I used coco for seedlings without buffering the coco. I know now lol next time will use jiffy as it's not coco. It looks better today so I'm going to wait a day before I throw stuff at it and pay attention to new growth before I do anymore as it's showing signs of growth again and perking back up. The coco caused all this is why I got so low on magnesium and got the stripes and all down hill after. Me adding all the extra cal/mag has gotten my stems and branches back to green from blood red/purple and green coming back to leaves. I currently have 2 stones because I'm not using the drip currently and I figured it wouldn't mind the extra o2. ph is 5.8 I check in morning and befor bed. usually goes up to 5.9 to 6.1 and I correct. Water temp stays between 68 and 70F Hydrogaurd came yesterday so I added it to bucket. RH is at 60% Thank you for your help.

I use GH 10 part light feed I was having problems with mixing ferts and ec/ppm being to high but I think I figured it out. I'm going to try this mix silicon, cal/mag and base ferts together. then mix up additives together separately then add it to res until I hit my ec/ppm. this way my base ferts don't get reduced from diluting it down with distilled water. And this way the only things reduced is my additives and not my base ferts.

I've never managed to get seeds started in Jiffy. 100% failure rate for me. Others have had mixed results but they have a really low pH which is a big problem for cannabis and lots of other species too.

You got to get them off to a good start for the best end result I find. Stress impacts them negatively at all stages in my experience re end result but I always do my best to fix them and grow them out to harvest if I stress them by accident. The results can still be awesome!

[VapeGod330]

Yeah she seems to be perking back up so I think I'm going to watch it over next day or so and see what new growth is doing so I don't over react right now and make things worse.

Yeah I keep thinking if it's worth it to continue with these plants because I may end up with very low yield now.

Nice looking plants in your pic. I hope one of these days..

[VapeGod330]

Ok ? when you guys add cal/mag do you add what the chart says or do you add 5ml a gallon? or do you add what chart says plus 5ml a gallon.

[Bluey]

I am using different nutes to you but never have to go more than half strength. I have gone higher but had issues with too much N.

[VapeGod330]

same I just lowered it 150 ec from 1050 ec to 900 ec like 640 ppm

[Bluey]

I think you got your units mixed up.

A plant that size in coco I wouldn't be giving it more than maybe 1.0 EC. Not sure how that translates to DWC though. What make and model pH meter and EC meter are you using?

Google a read on EC and ppm scale and also TDS.

I find EC easiest to use. No confusion
