I'm kinda worried as this problem has only reared it's head over the last few days. I noticed a couple of little holes on one of the fan leaves yesterday - initially thought it was cal/mag, but the leaves on the same part of the plant are turned up (slight over-fert?), so I don't want to bump up the nutes and risk nute-burn. There are also what looks like the beginning of a cal.mag def. on one of the other parts of the same fan leaf. All other leaves seem to be healthy.

0.8 seems to be a good EC for the plants at this stage, and i've heard Satori don't like loads of nutes, so i'm kinda wary of over-feeding. It actually looks like something has been munching on the leaves, but i'm definitely pest-free, so has anyone any ideas?

I really don't want to fuck up this Satori as it's a belter. The growth has been explosive and it's definitely a mum if it's female, so any help would be much appreciated guys.

No, that is not calcium by far, looks more like a dry heat, try moving the light up a bit...... that is leaf curl due to heat.....

Your plants look hella healthy btw, so I would not do anything or change anything for now until they get bigger when they require more food.....

congrats on some nice plants :yes:

Thanks for the kudos fellas - but I now have another problem and i'd like some feedback if anyone has any idea.

This started happening a few days ago, and i'm stumped. Nothing has changed from the above description, except a res change on the 2 plants in question. I live in a soft-water area(EC 0.04 from the tap) and i've performed res changes before without this happening.

Do I need to worry?
