So I have 2 Sour Diesal Autos from Seed Supreme and I snapped one whilst trying to do LST (I did it after a feeding and am a newbie so didn’t know how stiff the stem would be). About 1.5 weeks ago.
Anyway it still had one original leaf and so I thought I’d leave it to see what happened and it sprouted a new stem and new leaves and is growing quite quickly. The problem is there are some orange/rust spots forming which looks to be calcium deficiency.
I am a complete beginner so I could be way off but my setup right now is that they are not in a tent (I don’t have one yet) under a Viparspectra 450 light which is at R - 80% White - 100% and Blue - 100%. Which is 18" away from the canopy.
I have 2 oscillating fans to move the air around and a knee-height humidifier as we are in NY and its humid now, which fluctuates the humidity between 60-70.
I used the Supreme Soil from A Pot for Pot’s kit in 5g cloth pots, the soil is hot so I’m not sure if the new stem will be deficient in nutrients but maybe because of the LED its having cal/mag issues? The other plant is also LST’d and is doing great with no signs of deficiency.
The healthy plant is in pre-flower so the last feeding for the first time, I gave them 1/3 of cal/mag and 1/4 Tiger Bloom from Fox Farms, I started small because I’m cautious about killing the living nutrients in the hot soil with synthetic nutes but that’s all I have for now. The water pH was lower than I wanted at 6.2 but still manageable, just not in the calcium range as I’ve read that’s 6.5 and up.
I don’t want to over-do it with the synthetic nutes so I’ll do a plain feeding with 6.5 pH water next so that the regen plant can take up some calcium and magnesium and then I’m open to suggestions about what you think the issue is or what the feeding after next should include.
The lights are on an 18/6 schedule right now but I’m thinking of setting the colour spectrums at 100% and switching to a 24hr schedule now that the healthy plant is in pre-flower to promote bud growth, again open to suggestions about that.
Even if you tell me the regenerated plant won’t yield anything I thought I’d try as I am learning as I grow!
Thanks for any advice.
