I'm after having some very wonky looking bottom leaves that the plants grew out of and ended up fine. Those orange/rusty bits I also had on my last grow, which I attributed to calcium toxicity. Are you adding extra calcium by any chance?

It looks like the soil is too "Hot" and most likely they will get past it because the new growth looks ok. Just in case though please fill out the form.
Please fill in this form: (copy and paste part is below, this first one tell what specifically to include)
-Problem: (brief description)
-Medium/grow method: soil; soilless-- coco, or peat based like Promix, etc. (please provide the actual product name); DWC, NFT, etc.
-Feed and supplements used: include brand, dosage/strength, frequency of feeding and watering (alone); method-- by hand, drippers, rercirc' or drain-to-waste,... N-P-K #'s too if you can!
-Water source: RO/DI; tap- dechlorinated-?..... EC or TDS reading; pH (don't bother with this on RO/DI, do bother with TDS/EC though to confirm it's working well enough)
-Strain and age
-Climate: night and day ambient T and RH%; res' temperatures; any extremes in T/RH% exposure
- Light used: HID, LED, COB, combo of,... wattage; light cycle hours (20/4, 18/6 , etc.); distance to tops....
-Additional info: PH in the root zone. How long have the plants been affected?...How fast did symptoms appear?... Anything else you think might be relevant..
--Pictures including WHOLE PLANT PICS, and troubled leaves.. use normal light or flash as other light sources ruin color rendering, critical for diagnostics! Turn off the grow lights.

Problem: leaf curling upward at tip, burn mark on leaves but may be from watering with a bit of fishmix)
Medium/grow method: biobizz all mix potting soil
Feed: and supplements used: biobizz root juice week 1&2 (quarter strength) and fish mix quarter strength (1 watering)
water source: tap water with biobizz ph up to get 6.4 ph
PH in the root zone: not tested (note to self must test lol)
Strain/age: fastbuds purple lemondade , 2.5 week old
light used: Mars hydro ts600 , 24/7 and around 18/20” from plant
Climate: usually 26/27celciusn and having trouble keeping steady humidity so bought humidifier etc but as it stands humidity is usually between 56%-65%
Additional info: came home yesterday and noticed the curling, my heater had cut out so temp was 18celcius, only they 2 leaves were affected

Nah, literally water and some root juice quarter strength until start of week 2 I added some fish mix quarter strength for 1 feed and now this. I’m growing in biobizz all mix potting soil and I was warned at the start about the hot soil tbh
Thinking just sticking with straight PH’d water for the next feed or 2 and see how she goes
Thinking of sticking with just PH’d water for the next couple feeds to see how she goes what do you think?

The Biobizz All Mix can be too Hot for starting autos. You should be doing PHed water only for the first 2 or 3 or 4 weeks or longer? There is a lot of fertilizer in the pot. Your plants will tell you when they are getting hungry. Then go light ~50% strength nutrients every third or fourth watering. Do you understand the concept of balanced nutrients? If not go read this post I am working on and see if it makes sense.
