Hi Guys! \nHave had a few problems with this Cycle, Have done 5 or 6 Previous without these sort of issues.. \nAs the Photos show the Leaves are browning out and curling up/Dying on some of the Plants, There are 28 in the One Tent however there is another tent with 10 Larger plants. The pots are 9 Litre (2.3 Gallon) I am unsure of the Strand of Most of them however there are 5 AK47s among them. These are being grown in Soil, They are 2 weeks into Flowering The Water from the tap PH is 8 however i am bringing it down to about 6.7-7.0 each water, Since Flowering I have fed them Bloom Nutes (CANNA) and on their 3 week Veg I didnt give them any. \nI have 3X 600W HPS currently (for Veg had 3 X 600w MH, There is a 150mm centrifugal fan extracting the stale air through a Carbon Filter, The Fresh air in is being brought in also through a 150mm Fan howeevr is on a Y duct venting this and the other tent. As more air is going out than in It is creating the correct pressure ( i think) The Temp sits between 26-29 Degrees and I also have a roof mounted Pedestal fan circulating air throughout. The humidity generally is about 40-60% I have Co2 Injecting 4 times on the LIGHT period which stays on for about 3 minutes , I do not have a flow meter so I have guessed the Pressure however it may be too much (get it cheap so not too bothered) Could this be bad for them?What is causing them to transpire so quickly as Most people need to only water every 3 days, Mine wilt if left any longer than 1 day. The Larger Plants in pictures are from 1X tent and the smaller ones are from the tent that some are starting to show problems The current Light Period is 12/12, My temp is good, The air flow is good,There is plenty of space however they are starting to deteroirate, Unsure if it is a deficiency, Or perhaps a disease, At one point we had quite bad spider mites so not sure if the Organic spray has cause this browning however in the last dew days it has got worse,They transpire rather quickly and I have been having to give them 1ltr(0.3 gallons) of water per day \nPlease see photos, Any advice would be vry much appreciated \n \nRegards \n\n
Upon Doing some research There are a few things I think it may be? Co2 Toxicity/Burn Foliage Spray Burn Manganese Deficiency
this was my first grow....My plants wouldnt bud as much as i would have liked them to IMO rootbound kind of compounding a defiency of sorts. TOO MUCH NITROGEN in flowering did it to my plants
I can give you suggestions but ur not gonna like what im proposing for example all your flowering parts need to be cut off and all that needs to be revegged properly in a bed of soil. Like a soil container the size of that entire room. Now thats gonna take some perlite to drain. your roots cant breathe man they are all on top of one another
Mate ...! root bound to fuck ...an back ..budget 1 us gallon per month or(better) 1x liter of soil per WEEK the plant is with you, 12 weeks(3months) 12 liter minimum ...please~!!! include 30% perlite in them pots to prevent the above nightmare
Upon taking one out of the soil there is still plenty of room for the roots, in no way are they root bound, there are only 5 weeks with me so any other ideas
Man I'm having problems very similar to yours, around the same amount of soil too, I'm trying to foliar feed with cal-mag and giving some high p-k food
DUDE USE LESS NITROGEN. i dont believe a plant 6 feet tall in a 6 inch container has space for roots. Thats rediculous
Beleive it or not have a look at these photos, These are the same, Weeks later, All i did was give them a flush, Several people mentioned they are rootbound however they have come along very nicely.
You don't have an issue. Ph is proper so your girls are pulling nutrients from their leaves. I'd flush with plain water from here on out. When you think they're ready for harvest, fill them full of water and let them set in the dark for three days. You'll be glad you did.
