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…

Don't know what's causing
What would be causing this? I think the one pic with the limp leaf may be from intake fan flow. Also this is just on the bottom leaves. Thanks

Lockout or not enough nutrients ?
Hi grow fam, I’m starting to see some slight discolouration on a couple of leaves. I’m wondering if it’s being nutrient deprived or locked out. I am leaning on the side of caution by using GH’s light feed schedule. No signs of root rot inside the bucket

Hi to all. My leaves are turning yellow and I have no idea if they lack nitrogen or if they are over fertilized. Thank you very much for the advice.

Calcium deficiency or overfed?
Hi. This is about my Apricot Auto which already suffered the yellow tips/edges. I took that as the result of heat/light stress. Now she also developed discoloration and brown spots on some of the leaves. It looks like a Calcium deficiency to me, but I am quite uncertain. Thanks!

Older leaves are yellowing, brown/red rusty spots, dying tissue, red stems.
Older leaves have brown/red rusty spots and looks like dying tissue in between the veins. Burnt tips, and yellowing leaves. The soil was really dry and my PH meter was 0.4 too high. I gave each plant 3L of water with EC: 0.0 PH: 6.4 to check runoff. Runoff was PH: 6.1 EC: 0.8

Age or Deficiency
I have noticed one of the girls fan leaves have all started turning yellow and drooping. It looks like they are turning from tip to stem and some of the smaller leaves have also started to turn. Is this due to age or a deficiency of some kind?

Newer leaves also turning yellow at the tips. Flush?
Newer leaves also turning yellow at the tips. Started to give the plant Terra Bloom,Sugar Royal, Pure Zym and power roots again after only giving it water for 2 weeks long. Is this a nutrient burn and will a big flush help it out? Doesn't a big flush overwater the plant?
