Cannabis Troubleshooting

guys i have an infestation of fungus knats (along with pythium ) in 2 of 3 G-rooms. all the roots were brown and slimy. the leaves were dying (yellow, brown, brittle). i have been flushing the grodan slabs (in crop boxes) with 5ml per liter of microbial and also adding 2ml per litre of microbial to the nutrient solution for the past 2 weeks. i have also sprayed the underside of the plants where the scarid fly have been observed - firstly with a lot of confidor, then 3 days later with with mortein house and garden. after 2 weeks if you look under the crop boxes there are some very thick, white and healthy roots sticking out amongs the dead roots. also there is…

I have some white russian growing right now and they were all going great up until now....The lower leave's stems are starting to just give out and at some points in the stem its hollow like. On all of the plants, the main stem has a split that goes right down the middle of it. Around the split its starting to turn a a dark brownish color. Also some of the lower leaves are just drying up and I've given them enough water. I have no clue whats going on and the split down the stem is really bad to the point where you can see right through to the other side. Any one know what the problem is? I was thinking root rot.....but I have no clue what it really could be. I posted the …

Grow : Outdoors Strain: Tai Satvia Medium: Compost (need urgently) Grow Status : Sprouted, currently veging well & mostly sexed 3-4 Fem/3 Males Male to be matched with a different strain.

I plan to pot up to 25-30 lt pots in approximately 3 weeks time. I have been unable to find an outlet for "seals" compost which has bee suggested to me already. I tried…

Was wondering if anyone knows the changes a Satti goes through when she's going to seed ... does the structure of the bud visibly change .. I ask because I am worrying over a couple of males that have popped out recently in my GR - I'm pretty sure they were chopped well before any pods could have opened...but ya never know. Maybe its paranoia but I fancy I can see little seed pods forming .. don't really know what they look like and I may be imagining it ... the buds could simply be changing because they are getting closer to finished ... anyway, took a pic and would appreciate any opinions or feedback .. especially if you've seen a satti go to seed before

This ought to clear up the picture to what's really happening with your plants!! The problem with this plant is it has been burnt from to much heat from the lights

I rely on total blackness in the GR at night because the chamber has light leaks .. shit !!!!…

Hi all, I had 4 seedlings growing inside in my autopot hydro system. The looked pretty nice and were all about 6 inches high with 3 or 4 pairs of leaves. On morning I thought some of the leaves looked a little pale, but did not think too much about it. Next morning I noticed so leaf damage in the middle of the leaves. Small holes had been made in the leaves but some veins still spanned the holes. I also noticed small black dots which I soon figured out was caterpillar shit! I then found a few a small caterpillars that are now in caterpillar heaven. I sprayed the plants with white oil / pyrethrum mix, but the plants did not seem to get better. I could see no more…

ok my mate was 3 weeks into flower i went on holiday and left him to take care of them now he didnt check the water for a week and when i got back i seen crispy and yellow leaves all over my plants when i check the nutrient level it was off the stick so i have brought it all down to 14 hundred again is it worth letting them go or should i just pull them out and start again it seems buds are still growing but leaves are all f**ked up

can anyone identify this problem? it looks like its just on te top leaves ... seen it getting worse for a few days could be too much water .. too little nutes .. too little light (just replace dthe 3 growbrites with a SonT 400HPS) this kinda thing has never happened in the aero.. so it must be a variable specific to medium - the plants are sitting in a clayblaa/perlite/vermiculite mix and get hand watered and nuted ? thats all i can think of as background any ideas appreciated
