Hi, I am a first time medical grower and have run into problems. My temps range from 76-84 in the day and to low seventies at night. The leaves on my plants are turning yellow could this be nute burn? I added some revive from advanced nut. to them yesterday because they were yellowing but the yellowing has progressed I watered them also. Do they looked under watered still? I have no idea what wrong please help here are pics.

are they nitrogen deficient???? that is what I am thinking any thoughts?

Not nute burn. What nutes do u have in anyways?
Whats your PH?
They look like they need more light and some Nitrogen, either that or your PH is F'd...

ok well I dont think I need more light I have a 1000 watt for six plants, so I am going to the store now to buy some test strips because I read hat the soil testers are not accurate.

I am not using nutrients yet. should I be? This is my 3rd day with these girls I am assuming its the ph I will be back with ph results.

Oh, well then u don't need light!
I thought a couple looked stretched, my bad...
The reason I thought u were using nutes is because u said u thought it may be nute burn. U could throw in 1/2 seedling strength and see how they react.
Nute burn will show up on the very tips of the leaves as yellow and then turn to dead leaf, in that case flush...

Do u have a pest problem?
I see a couple of yellow spots in one or two pics...
Also, what are your temps in there...?

no pests at all. I baked my soil sprayed the room and clones with neem oil when I got them. temp is 81 right now. I just bought this soil moisture and ph meter that the hydro store says is accurate

how do you guys test you soil ph?
