I am growing with promix hp, believe I caught them in early nute lockout due to slightly high ph in the water 6.3-6.5 I adjusted to 5.8 and gave plain water tested runoff at an extremely high ppm so I continued only giving plain water for the last 4 waters but I’m still noticing more leaf tips turning yellow.. this is my first indoor grow on my own, 6 plants all separate strains, 5x5 tent with a Mars hydro ts3000 I guess my main question is #1 is it possible that my plants are still showing symptoms from 3 weeks ago? Also I wanted to flip to 12/12 this weekend but would some of the leaves being yellow mess up the flowering phase, should I wait?

As has been said, it's not a ph issue. ProMix HP is buffered, I use it with well water @ 500ppm and mid 7's ph.

No ph down. 3 gallon fabric containers.

I'm not familiar with your nutrients but I am currently using Mega Crop one part which is also ph buffered.

I may have missed it but what is your water ppm's ? And with nutrients added ?

In both Advanced Nutrients M/G/B and Mega Crop one part I couldn't go much over 1000 ppm without at least burnt leaf tips.

Of course I had to test how much is too much :mrgreen: Subject was an Early Miss Auto @ day ~90 (?). This was feeding 1.89L every day in a 2 gallon plastic pot. @ 1250 ppm. On the third feeding burnt tips appeared, on the fourth a 1/4 of the leaves were brown, sigh..

A 3X flush, ppm down to 900, all good with less than a week to look as she should. And the fan leaves are trimmed anyway so no foul !

As one who used to be prone to overfeeding, your plants look pretty darn good, I'd give them another week to fully perk up before flipping...

Good luck.

Cheers

Water ppm about 200 with no nutrients, once full mix is added its around 900, 5 gallon fabric pots, i water about a half gallon each plant, and let it dry until the pot feels light/ top inch is bone dry I also do a feed, water, feed.. I know these plants are strong and can handle a lot but everyone knows the gut wrenching feeling of looking at your plants and seeing any symptoms of sickness

Well then...

Not sure if my grow is relevant to yours..

I feed only MC at Every watering.

My last grow in 3 gallon pots received 4L every two days. What is your watering frequency ?

I would be inclined to cut out all the additives for a while, observe and add them back one at a time.

Any advice is great advice I love reading other people’s experience, and I water about every 3-4 days.. I cut the nutes for about two weeks and gave them a couple drinks of plain water and today noticed much more of the leaves seemed yellowish.
