Hey ya'll, I'm a new grower about 3-4 months now and i gotta say the list goes on and on when growing weed!! Lol. So, I've had numerous things I needed help/tips on and always had great luck finding the answers on forums like this from people like you
. Now that I have a tiny bit of experience its time to post my own thread, since i cannot figure out what to do. I chose RIU since its always been the most informative, naturally. Now to my problem, I'll try and make it short and sweet.
I am using canna terra plus, about 45-50% perlite(rinsed) in 3G smart pots. I have a 4x4x7 gorrila bud tent and a 3x3x6 for veg. 400w MH in veg w/ air cooled hood with 400cfm fan on speed controller. This set up is fine so far rh and temps are perfect basically. 1000w HPS in flower w/ cool tube reflector. I realize now i shoulda just started with 600w but learning the hard way. Atm its set at 75%(750w?) and when lights on i gotta unzip the tent to maintain 75 degrees. I live in a cold state so with freezing weather coming I'm just now figuring out how/where to vent this air. Its currently in heated garage and airs just circulating around in there. I'm gonna hook it to my homes ducting and use the heat in my house from lights this winter.
The plants in veg are beautiful, always look perfect, no problems. But when i put them in 12/12 to flower after about 1-2 weeks i started to notice purple stems and it slowly killed my bigger fan leaves. I checked the ph runoff at next watering(ph 6.5) and the runoff ran a ridiculous ph around 5.0. I have always done feed, water water. I definetly am not over watering as i let em dry out i probably under water in fear of over watering lol. I then flushed with 5g of ph'd water and it barely brought ph up. I waited about 4-5 days and flushed again and took the sample to my hydro shop guy who said i have successfully flushed it and to feed it at 20ml canna terra flora/gallon at my next watering which i did around 4-5 days later. Well I'm currently in week 4-5(have a notepad in garage, too lazy atm sorry), and my buds look beautiful. But my leaves are all dieing off!! My ph runoff has dropped back down into the 5-5.5 ph. Hydro guy says dolomite lime is "ancient" and no one uses it so he claims. Not what i see on the forums so i have some on order should be here any day.
I should have mentioned before I use canna veg and canna flora for nutes, and i have ph up/down so i always ph'd my water/nutes. Thats all I've ever used.
I have looked relentlessly at photos articles forums you name it and cant quite figure out what to do. Will the dolomite lime added to my medium fix my ph dropping issue? In time before all leaves fall off, prob lost about 20% of them so far? I just dont fully trust my ph guy from some things he's said, example: tells me to just use ph up/down to fix my soil/medium problem. But after researching i found out that no liquid will be able to permanently change the ph of the medium, so you have to add lime or something.
I attached some photos hoping for some ideas of exactly whats going on and what i should do. Purple stems by leaves>leaves turn pale>leaves turn crunchy and literally fall off. I have looked at mag,phosphorous issues that seem to link but i also have a ph issue so i dont wanna do anything assuming that it my problem. Thanks for reading this long drawn out post and appreciate any help i can get. Also thanks to any previous poster that has already helped me hahaha!
Also in flower tent is 2 blue mystic and 2 freebies I'm guessing a sativa since its lanky and not bushy at all, grew tall and i think i waited to long to start flower so I had to put a trellis in there to hold them down lol #noobmistakes.
