Depends If coco is present in your substrate. If so then I would use it more often then not coco absorbs cal mag.

Purp stalks, weak leaves.
Hey guys i noticed that my stalks were all turning purple and my leaves are curling. Is this a nute lock out ? Or is it light burn ? I started them under a pretty powerful Led but still getting new growth through the last 2 days. They look thirsty but medium is still soaked.

Nitrogen Toxicity?
Not sure if this is nitrogen toxicity or normal leaf color. Crinkling was caused by too much light and the fan. Got better in 24h after adjusting grow light and fan. Plants are starting week 2 of veg, Hulkberry Auto. Medium is light mix soil.

PH all kinds of fucked up!
Urgent update. So it turns out the issues all alone where the soil ph which after testing it was PH 3.2 π³ I have flushed with ph 6.8 water and then added some epson salts bringing the final ph back to 5.6-6.2. I then topped the pot with new fresh compost. Will she survive?

Advice on next feed.
So just before I water tonight I want to ask what some more experienced growers would do instead. I'm getting near the finish and honestly just want to make it there without losing too much bud production. I think my next water tonight will just be 1ml of bloom/l, inputs?
