I made a post about the mh the last 2 weeks. It's not proven but trichomes are like sunblock from uvb rays. The mh produces uvb rays and make sure you take the lens off the light or it won't work. If you have an air cooled with a lense that is.
I’m going to need to do some reading today I’ve got some crazy dark pink/purple stems on the AI’s. I think I’ve read this can be a strain thing or caused by lights being too close. I don’t think the light is too close 18†as mfr recommends. Vipsrspectra PAR 450. The odd thing is the under side of the stem (mainly in fan leaves that I noticed but I got hone about 5 am so didn’t really thoroughly look through). Noticed the light exposed side was purple while the underside was green.
Light is not too close. I have Viparspectra 450 Reflector series and kept it 15" during flowering... Plants closest did best. Probably going to allow them to get down to 14" on my current grow.
If color of stems is only "symptom" I do not think it is cause for serious concern... but is curious.
Reading on main site sounds like a strain thing here since it’s the only symptom. Just thought how it was green in the half not exposed to the light was curious.
Low of 66 high of 73 in the tent so they are staying a bit colder in there in general maybe that has something to do with it. The main stems are green with streaks of purple/pink on some. I think everything looks good so I guess it’s fine lol.
It’s a feed day for the big tent. These plants are way thirstier than the AI’s but the tent is about 4 degrees warmer and is a few % lower in RH. They will be getting week 4 fox farms nutes full strength of what’s listed on the feed chart with silica and cal mag. I’m not using flowers kiss or the microbe brew but everything else in the fox farms soil feeding chart. This is day 24 of 12/12. I am super impressed with the WW1 plant. If I was going to be starting another grow after this one I would probably try doing some monster cropping on her.
My torpedos had pink/purple stems on only mature leaves, never any new growth. I never really thought anything of it. With the other tent all being dark/purple strains all my plants had them.
Natural light is definitely best. Im glad summer is approaching I can actually pop them out on the back patio to check them now. The full dose system looks like it still working just fine. I see no burn
UrbZ one thing I noticed is my ph run off is now coming out a little lower than what I’m putting in now. They had been same in same out. 6.3 in both WW were 6.1 out, both GSC were 6.2 out. Next plain water day I’ll hit at 6.8, guessing there’s just a bit more build up in there with the full strength. Added bembe this week and it really took the pH down. I had to add 2.5 tbsp of ph up to get back to 6.3.
Nice looking good. I was actually thinking of trying to reveg one of my girls after harvest outdoors. Replanting may shock it idk. Would be nice to see it blossom again. Idk if frost danger is over though still cold without the 🌞. Mother nature being kinda strange lately.
