hello im growing 2 early girl cannabis plants under a 250 watt hps bulb and they are 4 weeks into flowering, im feeding them biobizz bloom every day about 3 to 5 ml per litre. my plant leaves are turning brown and a little bit yellow and dying. this has started at the bottom of my plant and working its way up any ideas? also my plants are not budding very fast i should be half way through flowering but the buds are just starting to come!
thanks
It could be one of two problems... 1) It may be under fertilized. I was thinking with biobizz you were supposed to use like one tablespoon (15mL). And during that initial stretch the plants use alot of nitrogen. Or... 2) It could be a pH inbalance which is locking out nutrients. I would say it just alittle underfertilized but test the pH first so you don't possibly just make it worse.
Hey wheelerd :thumbsup:
My opinion you are feeding them tooooo much!
You should not need to feed them every day.
Regardless of the strength of the food every day is a lot, give them a drink about every 3 days and alternate between food and just water.

Good Luck

wow i didn't see that it was 5ml per liter... That is too much. I was thinking 5ml per gallon. But yeah it still looks like a ph problem. If you can check the pH.
i dont have any thing to check my ph with!! im going to try not feeding them for a while
If you stop feeding it could make it worse. Try giving them clean water and a cup full of wood ashes. Chances are that your soil is too acidic. Wood ashes are very alkaline and have alot of potassium. It might be worth a try.Quote:

Liquid drops are very cheap and you can find them in the pool section or aquarium section of any box store, or at a hydro shop! No excuses, go get yourself tested ;)
PH is very important and you must get atleast the test strips that cost like $5 for 100. I had a new cool meter and never thought to calibrate it once. Ya, lets just say big mistake. I check my soil runoff by flushing with a 6.3 and get a 6.5 out. Thats not too bad but tells me there is more alkaline shit in the soil because it went up .2, so it is really at say 6.7 which is good.
I then think to calibrate the meter and oh yeah big suprize. Im sitting in a 7.01 test solution and the meter reads 8.4... OH NOOOOO
That means this whole time I was adding 4.7 ph solution to my soil instead of 6.2 ph. This is horrible for nutrient uptake and why I was seeing such poor plants with slow growth and small bud sites.
Last time I go without a PH meter test, almost killed everything. luckily I have two meters and this was initially how I found them to be off.
Suggest smoking.
