Update: 5 days of 12/12. I developed both a magnesium and a calcium deficiency about a week ago. It's rare being that I use tap water so I increased the nute strength to 2ml FN Grow and 3ml FN Bloom and 2ml Cal/Mag and it has cleared up since. I'm not really sure if the problem was solved because of the stronger nute solution or the cal/mag, but I'm happy it's solved. I've had to increase my feeding to once a day because the larger plant is drinking 3/4 gallon per day. Some of the potential colas are growing higher than the others so I will have to do some supercropping on a few of them to keep everything even. I'm not sure how many lower grow tips I should remove? Considering that I've never mainlined before, I hope maybe one of you guys can chime in and offer an opinion?
I like to leave only 2 lowers per cola. One on each side Sent from my SM-G950U using Grasscity Forum mobile app
Update: 9 weeks from sprout - 10 days from 12/12 flip. Plants look great I think. I have eliminated the FloraNova Grow and I am now feeding 5ml FloraNova Bloom only per gallon. This Friday I will start adding 1ml of Liquid KoolBloom like the feeding schedule suggests. With the exception of a short lived magnesium and calcium deficiency there have been no problems at all. The nice thing about hydroponics is that when a problem arises it can be corrected immediately. I'm taking Soil2Coco's advice and will defoliate for the last time after 2-3 weeks of flower. I'm still unsure on how many grow tips to eliminate. I'm not sure if I will eliminate any at this point. I don't think I'll mainline again - I'll just stick with 2 toppings and lst from now on.
Damn Mick, they really filled in your tent. Looking great. I felt the the same about mainlining until that week three defoliation. It really shows the potential. I’ll make my final decision after harvest of course. Sent from my iPhone using Grasscity Forum
So I’m trying to sinch down a timeline. @MickFoster you vegged 6-7 weeks from sprout to flip? Sent from my iPhone using Grasscity Forum
Mainlines take awhile. I still haven’t harvested yet but I did two strains mainlined this run. Each got an 8 top and a 16 top. I would stop at 8 in the future and maybe do a nebulas manifold rather than nugbuckets Just my opinion. Sent from my iPhone using Grasscity Forum
