HELP! Growing problem or problems

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 .

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
 
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..
 
I have a question I hope you can help me with .The PH of my tap water is 8.0 - 8.1 . Is this too high ? After watering / feeding does the mixture of 6.5 PH move back up towards 8.0 ? Could this be my problem / issue ?
 
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 ?
 
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???
 
I drop the PH down with PH down product.
My concern is how long does the water / nutrient mixture stay in the sweet zone & does the PH creep back up well before the next watering.
Might this be a problem ?
 
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.
 
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 .
 
I am currently using Earth Juice Ph down Crystals. I have also used Generaal Hydroponics orange liquid.
47 hours after adjusting water to 6.5 , the water is 7.3 .
 
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?
 
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 .
 
If you are in a position to collect rainwater then do so for feeding to your plants. Nothing beats it.
