Help purple stems and yellow leaves

[islandman]

help getting purple stems and yellow leaves first grow want to flower but want the plants healthy first they keep having problems and i dont know whats going on tried nutes tried testing ph run off was 5.0 is that to low ? soil

The yellowing leaves is most likely a N deficiency. I wouldn't be worried about the purple stems. I don't do soil but I think the pH may be low.

looks like overfeeding to me and check the ph,if in doubt flush them out.it never hurts to flush plants at any stage of growth .5ph is too low for soil also remember in soil you have nutrients anyhow ,so it is very easy to overfeed.need more details to go into it further.goodluck

whole plant shots are helpful as well as details on the plant such as age and what you feed what medium you are in, etc. off the top looks like you're in flowering and your plant is hungry. i see nitrogen, mag, and a hint of phos def. if your pH isn't out of whack i would just feed them a little more next watering.

Re: Help purple stems and yellow leaves

What kind of soil are you using and what exactly are you feeding?

Growing in soil organically or our with chemical nutrients?

Yes.

the limp looking purplish stems in yr first pic may be P deficiency.

the dark veins on yr leaves may be Mg deficiency.

overlooking what may be tip scorch from severe underwater or over fert ... I 'd say an N deficiency too.

all these things may be caused by incorrect pH. when pH is wrong, available nutrients are not taken up properly.

then you'll get an imbalance of nutes in yr soil (soil?) which can mess things up further down the line.

flush first! then get yr pH right (cheap accurate soil test kits easily available). a VERY LIGHT sprinkle of Dolomite on top of yr soil then water in will correct pH and give Mg too.

then proceed as per nute instructions.

better look

better look

heres a better look at the girls let em go for 2 months ph down to 6.8 had problems so tested run off it was 5.0. So now i am having to ph up to 8.6-9.0 to have a run off of 6.5-6.9. Soil was happy frog and ocean forest with 3/4 a bag of light warriors dont know what happen next time going to stick to one soil maybe thats the problem ??? Put dolomite in there one time didnt see a big difference only feed em one time and they didnt react well.
Some of them dont look as bad as these but look like there getting there if something doesnt get fixed.

Mix your nutes with water and pH to 6.0 or 6.5

When you just water (no nutes added) be sure to use water with a pH of 6.0 to 6.5

It's not the soil mix,it comes balanced @ 6.3 if I'm not mistaken.

FLUSH that shit ....purple stems is usually a p def, but when they have purple stripes like on a racing car hence the term "purple racing stripes" its 90% of the time meaning a salt build up that has swung the ph low causing lockout..

Joe couldn't have said it better. flush. Testing the EC of your runoff can be helpfull if your having problems too. If your runoff is EC is much higher than the EC of your feed, the plant is not using everything your feeding. If a bit of extra runoff isn't enough to keep it in check then lower your feed.
