NEWBY needs some help desperately,

[3greenthumbs]

hi all, I got a dinafem cheese that started flowering 2 weeks ago. a few sporatic leaves are yellow spots with redish brown spots and the tips are curling UP. only a few leaves here and these maybe 5 or 6 total..stopped growiing also..just hanging on.. I flushed it ph'd 6.5 and no change.. i have no camera so I know it's only a guess.. any help would be great,
Thanks

When you flushed it, did you check the pH of the run off? If so, what was it reading?

no i did not..dumb newbie didn't know to check it. i do have 2 other auto growing beside it and they are fine.

also the tips are almost turning black on the bad leaves while the rest of the leaves on the pland are solid green no yellowing tips or anything else abnormal looking

Without some pictures and not knowing the pH of your run off it's hard to say. The spots are probably a cal/mag deficiency and the dead, up curling ends are probably a phosphorus deficiency. Since both are happening at the same time that usually indicates a pH problem. What soil are you using and what nutrients and the strength of the nutrients?

Muddy is spot on from the info you have provided. I was helping another noob out who also is running a few plants at one time and same thing... Turns out his soil ph is 4.5! Total lock out. Though, the other plants are doing fine... Some plants even within the same strain different phenos can handle abuse a bit better than others... If you can test the run off so we can try and figure out your ph and also what strength and what kind and how often nutes are you using? Sending a :karma Cloud: of : gthumb: your way that things get straightened out :Sharing One:

nuetral soil mix moss, sand perilite, 3 gal pots. fox farm grow big and switched to big bloom when it flowered. going by the bottle 2-3 tsp. per gallon every other watering. I have beast blooms which is higher p & k should I try to add to big bloom or maybe instead of big bloom.. I also have Hawiian big bud which is realy high p & k with no N.. thanks for all your help guys this forum is awesome.

I suspect you may have nutrient lockout caused by your pH being off. If that is indeed what's going on, then adding more nutrients won't help and could in fact make things worse. You need to test your run off so we have an idea of what your soil pH is. Next watering give them enough so about 10% runs out the bottom of the pot. Capture and test that. Let us know what it's reading.

When you say you have a neutral soil mix, it this something you bought or mixed yourself? If it's a brand, what name?

ph was just under 6 . i made the soil mix, 1/3 moss, 1/3 sand and 1/3 perilite. my other plants are doing fine, this is my second grow with the same conditions. My water is from a well and ph is well over 7 so I udjust down to 6.5.

 

[Muddy]

If you're feeding at pH 6.5 and getting run off at 6, then you actual soil pH is lower, probably around 5.5. If you look at this chart you can see that at a low pH like that all the primary nutrients are unavailable to the plant.



I would suggest that you add 1 tablespoon of dolomite lime, or as it's sometimes called, garden lime, to your soil. Mix it into the top layer right before you feed them. Dolomite is slow acting so it will take about 2 weeks until you see a positive effect from it. In the mean time, up the pH of your feeds to 7 and keep monitoring the pH of your run off. When you see it start to come up, lower the pH of your feeds until both the feed and run off pH are in the 6.3 - 6.5 range.

Next grow, eliminate the sand from your mix and add in the dolomite right from the start. Sand tends to compact soils and weed likes a loose, well drained soil.
