ok first off, im growing in an outdoor office in the backyard nately temps are anywhere from 55 to 75 in the day, and down to like 40 to 50 at night. just put the one reading 7 in flower today. have 2 more in flower already, 4 weeks into it and they have yellow leaves on like the first two sets from the bottom, but green and healthy up top. using tiger bloom and grow big on those right now, 1/2 strength every other watering. also just used beastie bloomz 1st time yesterday. didnt ph those 2 yet, just figured it would be the same because im using the same water. but now i realize thats kinda stupid.
