answered grow question 4y ago
Looks like a cal/mag issue starting up or PH is imbalanced causing a lock up.

yellow/copper appearance in some leaves after first run off watering
hi! after the first run off watering the girls seemed alright, sturdy and firm but some of the leaves (one leaf, 3 plants currently) experienced copper/yellow/orange tints . this is only on old leaves so looks like mobile nutrients. could this be cal-mag issues?

Excess or Defiancy?
Some leaves from the top of my biggest plant, Frisian Dew, turn yellow and brown. The others don't show this behavior. The plant is in week 22 and still needs approx. 4-6 weeks until harvest. The plant pot is fully rooted up to the surface.

Curly young leaves (help)
I have a little problem with the plants in my indoor (70x79x160 with 4 airpots each of 12 litres) since 2 days ago are decayed, 3 days ago (Friday) I changed the lamp mars hydro ts600 (100w) for a more powerful mars hydro Fc300 (300w) I do not know if it is the change of format, the power of the knob I left it at half that is in theory 150 watts of its total capacity 300w and at a height of about 40 CM. The next day (Saturday) I saw that they were the same so I proceeded to leave it at 40 degrees of power and I gave them biofish fertilizer to see if it was a question of hydration but today Sunday I realize that they are still the same. I don’t know if it’s the light intensity with the new lamp or that I over watered them 3 days ago on Thursday (I watered them with around 550ml of water per pot) and as I said before, when I saw them like that on Saturday I gave them biofish fertilizer, but nothing…

Over the last week, I have noticed quite a lot of yellowing of leaves, along with them drying out and getting brittle. Now that I am checking the PH of the nutrients, and adjusting to 6.0, I have no idea what's going on. Any insight as to what the issue may be, is appreciated.
