Temps are 65 to 70 at night so I dont think thats the problem. I have never had problems with the ph, and it is actually about 6.8

It can be caused by phospherous def. as well as many other things...and my temps are in a good range, so it has to be something else

try to drop the ph a lil i like mine between 5.8-6.2, mabe your plant want the temp to stay between 70-75, just make a couple small changes 1 at a time annd wait a couple days and see if it fixs it and remeber dont drop ph to fast i drop mine about .5 a day if it gets really high

i need to get a ph pen first,i was thinking about the milwakee ph pen,its a pretty good price at 20 bucks.i also need a small heat mat for my clones.they root fine but the mat will speed things up alot

i bought a ph test ket for like $15 it had ph up and ph down, and a vile, a dropper and the chemical drops, its not super acurate but it will keep you between 5-6

First of all, if you are growing in soil I highly doubt that ph is your problem. Soil is a tremendous buffer.

Second, we need to know your set up. Like what kind of lighting, how often you feed/water, ballpark temps and such.

Talk to us.

i have a 400 watt hps in a 4'x4' tent,7 foot tall.it has a 130cfm inline fan with passive intake.i use alaska fish emulsion for nutes.iwater every 2 days with 1 cup of water.now im watering 2 cups every 2-3 days,its showed improvement.iim adding nutes to the next round at 1/2 strength.the temps are 67-70 low and 78-85 high

 

[supernovagrowlights]

sorry confussed you whit a hydro post, go get a moister meter from walmart like 5 bucks

 

[snutter]

your pH is too high and is locking out nutes. You need to get it down to around 6.0 to 6.2 for soil, I believe. I am talking run off pH of course...
