Hey guys,

So a little about it. I planted it in pro mix seed soil w/extra perlite in those 4" square cardboard like containers. I did 3 the same, 2 kush&cheese and 1 bubba kush.

This plant took off, it was already on it's third set when it the others were working on the 2nd. Then the tips of the first true leaves started to get dry and curled up, then the middle leaves on the second set, the third set of leaves are getting a discolouration with yellow in the veins and green in the leaf tissues.

I hopefully am attaching pictures so you can see what I mean. Any help would be appreciated, I'm at a loss as to why she is affected and not the others.

Looks like a phosphorus deficiency

 

[Blankshots]

Well since I'm not feeding nutes yet, should I give it 1/4 strength nutes now?

 

[pandabacon]

Yeah start off slow see what it can handle phosphorus is pretty fluid for the plant to move so it will usually start at the bottom up or if its to cold it can't tranfer hence reddish/purplish colors people see in there plant when it gets too cold or from deficiencys

Blank'-- Promix is very lightly charged, so feeding should start withing a week or so,.. not sure what the compost brand is-? tried looking it up, to see what's in it,.. not a bad thing, as long as it's mild,... what fert's and supplements do you have? Symptoms are hard to make out in those pics, and could be P defc., but others are possible,... little details are the hints we need when something isn't glaringly obvious! reshoot please,... they are on the small side, likely because of underfeeding,... since they're photo's though, you have time to get them back on track!...

Hi, and thanks for the response. So the soil is a local company from the Okanogan of BC www.micromaxx.ca/specialtysoil/ the guy at the hydro store said the sell flats of it. said if I mixed with pro mix sphagnum peat moss I should be ok for a month or two before needing nutes. My nutes are a 2 step veg and bloom from Botanicair. The veg is Pure blend pro grow, and the bloom will be the same Pure blend gro bloom.

I'm using RO water ph'd to 6.5, our tap water has 288 ppm tds, mostly calcium so I can feed tap water to get my take from that, the hydro guy said that nute system is pretty much easy and all encompassing (he is our kind of plant friendly)

i have 2 other plants started just like this one, and they were trailing her by 1 1/2 sets of leaves, now they are twice her size.
I fed them some nutes 2 nights ago and a seedling root stimulator yesterday.

I'll post some pics to show you all three plus my feed... any help is greatly appreciated, and good vibes to you all..
