Thanks

In addition to a support ticket, please tell us what lighting you are using and how far your lighting is from the plants. One more question. Have you been misting or spilling water on your leaves?
Overall they don’t really look too bad.

I am using 2x LED samsung full spectrum grow lights. Actual watts per light is 90w so 180w.
The light was 30cm from the canopy but I adjusted it too 40cm now.
I mist my leaves often but my other 3 plants look fine however they are about a month younger Than the problem plant.
Strain: unknown
Regular (she shows female preflowers).
Cannabis Organic craft soil (just Cannabis).
Plastic 20l pot.
PH before feeding is 6.
Runoff pH unknown.
Ec is unknown.
Indoor.
Temp day 28 Celsius
Temp Night 24 Celsius (lights cycle is 24 / 0)
Ventalation yes. 580 CMH (m3/h) Flow rate.
Lights should really be at least 46cm from the tips. I’m going to guess this is why your leaves are clawing under. They should recover in a few days.
A soil pH of 6 will cause some nutrients to lock out, particularly P and K, which is not what you want when in flowering. It will really help you to get a handle on pH and your EC (or PPM.)
If you’ve misted with the light that close it can cause problems, and can cause the spurious leaf damage you see. You really don’t need to mist your plants. Your humidity should be monitored though. Most suggest no higher than 50% in pre-flower, and reduce it to ~40% when in flowering.
Good luck. You are really looking pretty decent and everything else looks pretty good.
