One other note does your tap water contain choline or chloramine.. the later does not bleed out. You need to add your acid and let it sit. Then readjust as necessary.
good luck my friend.
Yeah it's def looking like pH might be low... Looks almost exactly like what i was dealing with in a far back grow. I was using tap water as well and adjusting it to the correct pH, but for some reason the plants were not responding to it and it just kept making the soil more and more acidic even when I put in water with a pH of 8 It didn't help.
That's one thing I've been noticing with Fox Farm brand soils They like to go acidic very quickly. This is the last time I'll be using that brand. I've had less headaches with miracle gro not to mention the spider might infestation that the soil started.
Update ! Discovered my digital PH tester was way off. I used a PH soil tester tonight and the soil is above 7 !!
The big question now is what is the best and hopefully quickest way to correct this before I loose my crop.
Thanks in advance
I did the flush today with 6-6.25 PH water. The run off was around 5.6-5.9. Totally confused by that ! Didn’t feed, they were just potted up last week
Thanks for all the suggestions and advice 😎
Thanks to everyone, looks like a good flush with the lower PH water made a big difference. I along added some more soil to the top of the plant and lightly watered after the flush. I think that gave it some new food with the proper PH did the trick !😀 See pic ! Pics came out after first, then before. Thanks again ðŸ‘
johnb1963, thanks. I had a soil PH meter which was incorrect and lead me to believe the soil was too alkaline, was reading above 7. So I tried to compensate. But just the flush and a little soil on top and seemed to improve the color.
Thanks for your advice, really appreciate it ðŸ‘
Yeah i just started buying gallons of spring water from the store... 2$ for 3 gallons. The pH is good and i haven't had any issues since. The tap fluctuates too much plus the chlorine isn't good for growing in living soil. My soil pH problems disappeared and it doesn't cost much at all for a small grow
