Cannabis Troubleshooting

i have been given some house and garden shooting powder it says yuo mix 1 sachets per 100 litres i have a res of 20 litres as i hand water in coco so how much would i need for 20 litres. also has any body used the coco that comes in brick form as it would be cheaper to get that by post than a 50 litre bag of coco would like some feed back .cheers

just went into my grow room to find res near empty and water all over floor.On closer inspection discovered one of my pots overflowing.I lifted the pot out to see what was going on to discover roots had grown half the length of my return hose.I cant deal with this at the moment(have fixed immediate problem but this will probably happen again).So in the morning i was going to organize overflow lines on each of the pots,but this still doesnt solve all my problems so i would really appreciate some advice on this as its stressing me out.I have 20 litre sattelite pots with perlite as the medium.

After doing a bit of reading I have discovered that Neem oil, and specifically eco-neem is a good way of preventing pests in your garden. This year I'm doing a organic guerilla grow and was looking for a pesticide that someone can recommended to protect my plants from these little pests. I read a few times that people said Eco-Neem is not meant to be used on plants that are going to be consumed, making me a bit uneasy about the whole thing. Anyway all I'm after is a harm free spray that I can apply to my plants when I visit them to give them the best chance of surviving attacks, so something a long the lines of a Neem based product I'm guessing, or maybe one of those hom…

My first grow is going great guns, my system is working perfectly and I have three seedlings in there which are all from different bagseed collections (so different genetics with each one I would guess). I have one plant which is growng at the same rate as all the others yet it concerns me that it is a paler shade than all the others, I just took the ec up from .8 to 1.6 and started automated feeding in the last week. (see pics) can anyone help me work this out as I can not seem to tell why the plant is a different shade than all the others. (is this normal or is it a deficiancy or a nutriant problem?) to see the stats on my grow see "My first grow" by sassman (i…

Hey guys, I'm looking for some advice as to how to treat this plant. I've done a bit of research, and I'm fairly certain that the problem is phosphorous deficiency. No idea what the strain is, plant is about 2 weeks old, using 250W MH in growtent with exhaust fan and pedestal fan for circulation. This is strange however, given the soil claims to contain "controlled release fertilizers" (Yates premium potting mix). The plant seems to have slowly gone yellowish and has a rather large deep purple blotch on one of the leaves. I've fed it some ferts (Miracle-gro 15-13-12) to try and bring the phosphorous levels back up, and I'll test the soil pH asap. Any ideas…

is it allright to calibrate a tds meter(ppm)with 2.76 conductivity solution(1380 ppm after conversion)

First I am pretty new to growing I have grown in the past but only 3 plants at a time from ready to go clones. I am trying my hand at getting a SOG going had problems and still working at it The latest problem seems like a biggish one. I am growing in 4 900 ebb and flow trays I have harvested 2 trays so far and even though really small yields it was a good smoke. The next lot to come out I have the original strain I was using and a second lot from another plant the first lot seemed to be going well but the new plant had really small buds I just noticed it is seeded I mainly found seeds in one plant but I have found them in others as well including the original plant…
