Got some leaf claws here need advice :)

I bought them this last Tuesday.They are under 600w lights but they are only on 450 atm for 13hrs.Only two of plants seem to be doing this(both White W).I water them when the soil dries out and have not fert. them yet. Humidity is around 30-35% and the temp is at 70. Im thinking it is a possible calcium problem but i could be mistaking.Im also trying to stay all organic so if it is a nutrient problem would you know of any good organic ferts that i could use? Thank you

RU sure that your soil does not have slow release nutes in it already?

Im using Fox Farms Ocean Blend good stuff but need to solve this :/

maybe warm it up to the upper 70's, and keep night temps up too

well from what i hear around 68 is the best temp for them so i dont think it has too much to do with it? could be wrong but thanks good suggestion.

Have never heard that before, always heard upper 70's w/o co2 and mid 80's with.

when my girls get a blast of cold air from an open door they sometimes curl.
