They grow up so fast , my ladies are at 12 inches tall coming into week 3. I feed them 1 a week with a low solution of neuts and I will continue to increase every week until at max before they burn. As I go into buding I slowly introduce the flowering neuts and increase slowly until last 2 weeks before harvest. This system seem to make them excell nicely and grow at an amazing rate.
Curious if your 69° night temp caused that purple colors, or if that particular cutting/pheno just gets purple.....I've seen some ALMOST black they were so purple and others with no purple hues...I got 2 feebie seeds (3 weeks old now) that I decided to grow out with the Dosidos order they came with....A lot has to do with the suppliers genetics...Who supplied YOUR ATF.....looking great!!!..thx Steve A.
