Seems trouble coming from my hot soil.

Leafs getting yellow /white and buring tips.




-Medium/grow method: soil - I purchased from local store. It's a compost soil. Seems like it's a hot soil. It's the only soil i have access unless backyard soil. (unable to import soil as it's prohibited to my country)


-Feed and supplements used: No extra nutes yet. Just watering 5galloon smart pots every other day.

-Water source: City water

-Strain and age - Speed buds from female seeds / Cheese XXL from dinafem - All autos - 18 Days

-Climate: Always below 28C - Running under A/C RH 60% - 75%

- Light used: HLG 260W Quantum Board light under 24inches distance. Dimmed light to lower.


My wife accidentally transplanted all plants Only compost (yes without mix ) then after 2 days later switch back to composted pot mix by local store. Seems its like a nute burn since i am a newbie i am not sure.

After i thought it was a nute burn i flushed all plants with vinegar mixed water (PH was 7.5 and lowered to 6.2) and flushed water came out around PH 7.8 i am not sure.

Can anyone help,
please.

It's most probably your medium, ph is a bit low imo 6.5 is best. The older / more roots a plant has the better it can handle not so good medium. I'm not sure if flushing will remove the pre nutes from the mix to make it more viable, but I guess there's not much else you can do if it's all you've got. You can just hope plant will cope and grow through it,it's not so bad really not yet

Today i increase 50% more light and flush. (city water + vinegar @6.5ph)

Vinegar apparently is not so good to use for ph. Can't remember where I heard it but would explain a lot, try lemon juice or just get ph up and down. ( personally I'd just buy it) never used vinegar or lemon so can't comment but I remember hearing vinegar wasn't so good for it
