[blackfox]

Hello guys! Do you think this could be phosphorus deficiency?
I am using Biobizz grow, bloom,topmax. Its day 57 and 29 of flower and im still giving by shedule, maybe it is to little??
Plant is Black Jack auto from Sweet seeds.

Kida looks like she's just finishing up.

:smoking: ooooo,... very sexy! Superb strain mate,... so, the color expression is normal i believe for this strain (from the Black Domina side), but also, some mild P defc, can cause this as well,.. and the yellowing out even on the uppers,.. a minor micronute defc. could be behind that too,... Biobizz is good stuff, but rather mild; I see defc. with this line-up fairly often,... up the P input, or use a milder PK booster, and also add more of whatever product of theirs has the micronutes in it (like Fe, Zn, Mn, Mo, Cu, B, etc.)...

@GoAuto6 the plan is 2-3 more weeks, she needs to fatten up much more (i surely hope so) she˙s only 30 days in flower.


@Waira I think you are right, that and/or colder temp. my temps are around 23-24 day and 18-19 night. I read about somewhere that colder temperatures can cause something like this..

She'll go another thirty eating off her self and clearing all nutrients out of her self.
