Lights on 75 degrees 19% RH for the first month and a half I used cal-mag and water no nutrients I feed my plants every 3 days because the pot becomes extremely light the plant that is foxtailing it started off growing straight up... tall an linky.. I lowered the lights but it just kept growing straight up last month I started to give it nutrients pH my water check my ppm's but this is the outcome could it come from transplanting and disturbing The Roots
You dont have to feed every watering typically (the pot light because it has less water, not necessarily because it is hungry). When the rh is lower, the plants go through water much faster.
Ya that's really low RH.
Are you using tap water? I have tap water that's high in Ca (200ppm) and if my RH is low my plant drinks too much of my nute water and gets nute burn.
Low RH plant drinks alot. High RH plant drinks less.
If I added less nutes to lower my ppm the Ca from my water would then be out of balance and too high compared to the other nutes and I will get lockout.
In order to keep my nutes balanced and not overly high in Ca I don't use Ca-Mg and have to add my nutes at a little higher than whats typically recommended (for certain growth stages) but then I'm trying to control how much the plant drinks with my RH. I grow in hydro so this is possible.
For you, at that low RH, and using FF soil with lots of nutes in it already, I'd water with only distilled water so I wasn't adding to the salt composition after the water had evaporated. Even then, at 19% RH, the plant may drink too much of the water and dissolving nute solution as your water rests in the FF soil.
Do you pH your water?
I don't think your issues are from a transplant shock. I looked up the pink grapefruit strain and it seems to have some natural foxtail tendencies, but not as much as yours.
Your issues could be root issues, but many people transplant and transplants alone don't kill.
Did you transplant into same soil composition? Are you done with the grow? Dig up the roots and smell em, do they look white? Are they slimy?
Just curious if you've done a run-off test? PH run-off tests are notoriously misleading, but I'd be curious what your ppm would read.
