Hello,

Currently experiencing a slightly higher level of pH in my run off 6.8 to be exact (Coco) which I suspect has lead to copper deficiency. I am on week 7. What's the best way to deal with this. Would flushing the plants at this late stage be worth the stress it will cause to them. I am currently growing auto mazar "10-11 week Dutch passion" seed to flower.

Thank you

6.8 is not bad for runoff. whats ph going in? if these are auto's on week 7 and they will go a few more weeks, then I wouldn't worry. if going in ph is higher than 6.5 drop it with a few drops of vinegar. or ph down. a few drops wont effect anything.

Ph + - or vinegar will bring down ph. There are coco growers in here that say checking ph run off for coco is not accurate.

I would say either your input ph is too high or you have salt built up. I let my ph drift from 5.5 to 6.3 with a drain to waste and I don't check the runoff.

Do you have pictures?

 

[Micky&MalloryKnox]

I will try and grab some after lights out

 

[MR magoo]

again what's the PH going in??? that's what will tell.

 

[Micky&MalloryKnox]

Going in pH has been drifting between 5.7-6.3 sorry thought I replied with that. However I did have a little pH pen issue so it's definitely being going in higher. That lasted for around 5 weeks. The pen was a good few points out. (Always calibrate)
I originally thought it was nutrient burn but the yellowing never progressed past the tips. Some leaves are pretty dark in colour and some leaves are turning themselves upside down.

I would aim a little bit higher going in. 6.4 or 6.5 for best uptake. and who cares what comes out. I test my water to calibrate it stays the same, well water. if I doubt it I use calibration fluid to be exact. these plants, are their any pictures? at 7weeks ,what time do you think they have left?

This little guy is sitting at 7 weeks. I never kept track of seeds and there are auto mazar and a random free auto lemon seed was popped. I think this is the lemon. This plant is the healthiest in appearance with little yellowing tips and little leaf curling. The others can't be moved and it's lights on.

your plants are fine. I do see a little tip burn,no problem! not too much. I feed my plants enough to make tip burn, it tells me if I am pushing too hard, 1/4 inch tip burn is about as much as you want, yup they need to go at least two if not three weeks. keep pushing the bloom to them. after about a week, you may see some yellow leaves, this is natural toward the end of the plants life. you guys need some rep..... doing a fine job.
