Metamorphstarted grow question 5 months ago
I can't lower the PH in coco. I spilled it twice in a week, the first time with 12 liters of clean water with a pH of 5.9, today I spilled it again with 23 liters of water with a pH of 5.5, but from the drainage it’s still 6.86. What holds PH so much? The leaves already indicate

You shouldn't flush with plain water in Coco until the end. As it removes the Calmag buffer it has accumulated.
What is your run off EC?
Always feed with nutes in Coco just don't over do it with the EC.
To drop pH I will mix my nutrients and drop the ph to 5.0 . A couple of feeds later it will drop.
Your plants look healthy so I would worry .
Run off in Coco is ok from 5.8 to 6.6. so you are not far off .
Just lower the pH to 5.0 for a couple of days. (With nutes ) at a lower dosage if your run off EC is high .

If she won't lower, just keep feeding her with the proper ec, but ph your feed water down at 5.8. She will eventually lower. Once the planters runoff drops where you would like to see it 6 to 6.5 start feeding with a ph of 6.0. Your not way out now, not to much to worry about. You just don't want it to keep rising.

Brown spots on leavesWhat seems to be the problem with my plant? The old leaves get brown spots whereas the newer ones have yellow edges. Is it a pH issue?
Is there a fix to this?
I grow in soil and the plant is 4-5 weeks old.
Thanks for help!

Brown spots on older fan leavesSpotted some brown spots on 2 of the older fan leaves today. Any thoughts on what the issue may be?
Does not rub off- was worried about rust at first.
Some more info that could be helpful is that I am using RO water. Thinking about rasing the lights a little higher up too.
