What does this look like?
- Thread starter sacro
- Start date
The whole point was to get some first thought pointers 
But as info, this particular leaf is mid/top, new growth is very bright green (N def i guess) and 17 days into flowering. My runoff PH is all the way down in the 4.x numbers which I am now trying to adjust slowly with less nutes and higher ph water than usual. Normally I water with 6.5. Im thinking flush with 6.5 then measure runoff. If still low, water without nutes at ph 7-8ish. I kinda made up my mind its P.def and N.def caused by lockout due to the low PH. The blind question was to get some direct input
Ill upload some real pics of the three ladies later today and see if you agree or have some other advice I should consider.
Thank you for your answers so far

Bit hard to see this is two plants. My 3rd looks pretty much okay but shows some signs of the same problems as these.
I feed once a week, BioBizz Bioheaven, BioBizz Bloom and BioBizz Topmax. Also watered about once a week (addition to the feeding). What I did today is flush the three ladies properly with PH 7.5 and nothing else. After flush I added just 0,5 litre of water with BioBizz Bloom and Bioheaven, but at about 1/4th dose. I do realize this looks like nute-burn, but I didn't really feed them much more than 1/4th dose of what Bio Starter Kit says you use. In addition I'm suppose to use BioGrow as well through the whole grow cycle, but instead I just sprinkled some bone meal on top before watering. This should be slow working, adding P and N along with some calcium, and work a long time as far as I know.
The plants are grown in "regular" soil made for vegetables mixed with about 40% clay pebbles (Leca balls) which I now believe was a bad idea. After flushing and adding that 0,5 litre of nutes my last drops of runoff water is about 5.5-6.0 PH. Last time I measured I was at 4.8. Way too low yes. I know I should be careful when raising my PH, so for now I check my plants twice a day to make sure things don't get worse.
I currently vent the grow area with PC fans (if I crank them up to 12 Volts temperature sinks to below 20 degree C), and I use a 250W SON-T Plus at about 60cm above the top of the tallest plant, and I have a fan inside the cabinet to circulate and move the plants. My pot size is 18 liters and should (far as I know) be enough for a 1 meter tall plant (correct me if I'm wrong here). The ladies are on a 12/12 schedule like normal and was put into flowering March 2nd.
Anything I did not answer, please ask All answers deeply appreciated.

I vote magnesium deficiency. Epsom salt maybe?
Well actually I have no idea how to get that here. Any alternatives normal stores would have? This country is definitely not big on gardening stores and the selection is tragic if not worse :\Water in some dolomite lime. 3/4 cup:gallon or so.

Next best thing IMO is Ground-to-dust eggshell powder. Eggshells are used quite a bit in organic gardening as pest control, calcium supplementation or being used as a pH buffer. I'm sure there are other uses out there too I just can't think of atm. Take some eggshells and ground them up with a coffee grounder or a mortar and pestle or something that gets the job done. If I had to pick a number without knowing shell size etc etc then I'd say probably about 30 or so eggshells split between your two pots. This isn't a sure fix but eggshells are made of calcium carbonate which is the main ingredient in dolomite lime if I'm not mistaken. Eggshells also contain trace amounts of nitrogen and a few others I can't think of.
I actually posted a thread a few months back on the subject with a link to an actual study on the matter and the results were very much in favor of using eggshells in place of dolomitic lime . Here is the link to that eggshell study http://www.agronext.iastate.edu/soilfertility/info/eggshell-lime.pdf Here is a bonus link to something completely irrelevent but interesting none the less. http://www.sunset.com/garden/earth-friendly/starbucks-coffee-compost-test-00400000016986/ Quite interesting and notedNext best thing IMO is Ground-to-dust eggshell powder.

Thanks man, appreciate it Also as the plant keeps growing I am now pretty sure my main problem is potassium locked out due to HP and cal and mag def. The few leaves that are damaged shows sign of this. Just ordered a couple of PH and EC metres for proper testing. Not gonna upload more pics here unless I get new problems but if anyone got anything to add I appreciate it

I should add that the purpose of lime is to buffer your soil pH. This means that the pH will stay at a given pH. In this case 7. This is perfect for MJ soil growing. Eggshells will do the same thing for you. As for the potassium, you can get a free sample of roots organics from their website aurorainnovations.com all you pay is shipping (6$) in the sample request form simply make a note that instead of what is offered you'd like HPK. HPK IS very high in phosphorous and potassium. The bottle they give you should be sufficient for most of a grow of your size. Good luck.
