Growing problem or problems

[Duester]

The plant in the pictures is in a 5 gallon cloth pot . 1 -20-25 it was one month in. Currently the plant is yellowing many large fan leaves starting from the bottom up. This issue seems to be always happening shortly after one month into flower. I will be home in a few hours to post some pictures of this plant .

[Duester]

I apologize for being absent for so long , I had to pack up & move & im starting all over again.

Duester Per your post 8.2.
I am growing autos in a 70/30 (have used 50/50) coco/perlite blend in fabric bags. PH 5.8 for vegging, 6.0 for flowering using tap water and Botanicare nutrients, bloom booster, and Cal-Mag.

[Duester]

Thank you . Is there a reason for the change in PH between veg and flower ? Does all grow media require this change ?

[Bluey]

Duestar you need to make sure whatever calmag you use is compatible with the baae nutes you are using so if I were you to avoid possible issues stick to the base nute manufacturers calmag or other manufacturers recommendations

[Duester]

Thanks Bluey . I believe I can get some Dutch Science Nutrients.
I just posted a few pictures I took from earlier .

They are looking very happy but watch for nute burn, that is the tips of the leaves turning brown and curling upwards, can also spread down the outside of the leaf a bit and cause a little bit of cupping.

[Gingerbeard]

Other folks are better at diagnosing, so I'll just talk about our thing. But you are on your way to some fine looking dope.
Per your post 17.1
Plants uptake different nutrient, in different amounts, at different pH levels. I can only speak for coco. Soil is a whole other world.
Require is an ugly word. Everything we do is general information based on different experiences. Generally, the numbers I gave are recommended in the forum and are what I am getting my best results with. Someone might find their X strain vegges better at 5.75 than 5.8.
Find yourself a boiler plate and adjust accordingly. Experience will come.
The chart is from the GWE site. It is pH recommendations for soil growing. I am only posting it to show a little better what I mean by different pH levels. I don't know if there is one for coco.

[Bluey]

I can't help with that description. I use ascorbic acid, which is a lemon from my lemon tree to lower pH. It is compatible with my nutes and suppliments and will hold to 0.1 to 0.2 after a week in a tank that is not aerated.

Yours is rising fast. Are you using one manufacturer for your nutes & supps? What chemical does that manufacturer use for pH down? Is that what you are using?

[Duester]

Yes , using the same name for nutrition & supps .The manufacturer of the nutrition doesn’t specify a specific name brand of product for adjusting the ph.
I E Mailed the manufacturer for their recommendation.
I’m searching for some cheap bottled water to possibly use because of the high tap water Ph .

[Bluey]

If you are in a position to collect rainwater then do so for feeding to your plants. Nothing beats it.

[PRIMO]

Duester Sorry but I don't see the yellow leaves you'r going on about. What I see is a pretty healthy plant, that needs a little defol, maybe some lollypoppin. I.M.H. I would dial back the neut.- water ratio, Perhaps get a different neut. brand F.F or dyna-gro. with a compatible cal-mag product. Next time around try growing in a bucket of quality soil and see how you do. I feel it's more forgiving than coco or hydro.

[Gingerbeard]

Right again, senor Bluey. I saw the image but only read it was for hydro. It is also for coco.
This one is for coco Duester.

[Duester]

Appreciate the advice. I will post a few more pictures trying to highlight the issue I am having. ( leaves )
Should watering/ feeding change in any way about one month into flower ? Meaning totally wet the grow media .
Before flower I noticed dark lines in the branches . Does that mean anything ?
The person at the grow shop mentioned that i should treat the Coco Loco like soil . 6.5 PH .
I have some cal-mag coming that is same as my veg & bloom nutrients.
I will be posting more pictures shortly .

[Duester]

[Bluey]

The plant looks pretty healthy apart from one or two higher leaves fading and a little bit of nute burn.

What I am seeing is a grow that is 'spindly', narrow long stems with a bit larger internodal gaps than what is ideal. Not an indication of bad health but likely one or more of lack of light, lack of air movement on the plant or overly strong red spectrum.

Soil in flower is pH 6.5 to 6.8

Coco in flower is 6.0 to 6.4

Coco loco is what? Its coco right? Or is it soil? If its coco then use t he coco pH recommenation not t he soil one.

I think you minor discolouringis pH related so you need to change it that what I keep saying. Go the coco pH settings..

Close up pics of the problem stems. Can't see it

[Gingerbeard]

Research Coco Loco pH. Your shop guy might be right. It has additives and is not straight coco. Feed as soil.

[Bluey]

It has additives until it doesn't have additives because the plant uses them or they get washed out or whatever. Soil pH may be the correct approach but he needs to vary it..

[Duester]

I did some research on the Coco Loco . They , the company says treat it like soil. 6.5 . Using tap water that has a PH of 8.0 is this a bad idea ?

[Gingerbeard]

Using 8.0 pH water is not good (it is bad) unless your soil or nutrients have a way to lower that number. That was my case in my very first grows. I should have played the lottery for how lucky I got. That is not the case for Coco Loco.
Water and/or nutrients should hit your soil according to the pH charts I posted earlier if not mitigated by nutrients. I do not measure runoff. When all else fails, check the manufacturer's rec's. Dutch Science might not need pH adjustment.
All soils lose nutrients when flowering hits and are pretty much devoid of anything beneficial for flowering.
Nigh on 6 weeks since your last post. Are you having issues? If the answer is 'yes', follow that up with pictures. Also, if the answer is 'yes', have you been giving 8.0 and just now having issues???

[Duester]

Hello Gingerbread
Yes , I’m still having issues . I think I might have found my problem or just a problem .
Dutch Science does need ph adjustment.
I think the problem is possibility my tap water. It is testing out at 8.1 - 8.0 .
I’m talking with Bluey & he suggested to test the water. I did & it went up to 7.0 from 6.5 in 24 hours.
I will be checking it again a couple more times to get a bigger picture on how much the ph drops.

[Duester]

Correction on last sentence …. I will be checking it again a couple more times to get a bigger picture on how much the pH rises over time .
