Hello Everyone: I have three plants flowering one month in my grow tent. After the last nute watering on of the plants leaves turned a light green. I thought it may be nute overload but looking around I don’t see nute overload as symptoms of the pale color. I can post pictures when I get home. Any advice? I do let bags dry out before watering, maybe not enough? Thanks you.
It could be any number of things. We’ll wait for pics. In the meantime if you can help us help you by providing more information we might be able to see it in the information you provide on the grow environment.
A support ticket will help us help you. Can you please fill out a support ticket? Please include what type of water you are using (RO, distilled, tap.)

At new growth? like this? I see it with most grows I do but only the new growth. They turn the same color as the rest after a couple of days.

If at the tips, when flowering starts the plant experiences rapid growth and chlorophyll doesn’t develop quickly enough to keep up with the rapid growth. Chlorophyll is responsible for the green in leaves. As @Bonjoyle suggests, it will take a couple of days for chlorophyll to fill the leaves in with a darker green. It is a pretty common question among newer growers.

Here is a pic. It’s the plant on the lower left. It’s hard to see but the leaves definitely got a little paler after I gave them their last nutes. This is a Cannatonic strain and it is said that this strain gets mold easily for too much water. I have been practicing the “drench a drought” method for watering but I think I may have not let this plant dry out enough. I think it’s getting better though. Any advice is greatly appreciated.

That’s a nitrogen deficiency. Can be a pH issue or just plain too little nitrogen.
The support ticket in this case would be extremely helpful. Just copy and paste it in a reply window and type answers after each question.

Spiney - I just gave it nutes - FloraNova Grow 7-4-10, a healthy dose of about 2.2 EC and the plant went pale. The other 2 plants are fine. This one plant has always been my problem child, never grew right until I started the “drench and drought” watering (I think it was not getting enough water). Right now I’m letting it dry out a little more and it seems to be looking better, but hard to tell. Thank you for your interest in helping me. I grew once in the 80s but it was easy, plant and water and let 'em rip!

What was the pH of the solution before you watered with it?
Do you use a meter or test strips?
Tap Water or filtered? Or bottled?
Might need something like this…

6-7 based on prior solutions.
Meter
Tap EC .4
Hard to tell from the pic… is the lower growth the same color green? Or is it darker?
All the same.
Every plant it different and sometimes they can want more or less of a certain nutrient.
I would probably do a slurry test to see what ppm number is and also the pH of the soil.
Its easy to do, here is a video explaining the process.
The FloraNova line has a Bloom mix that is probably what is needed right now. Here is the feed chart for the line…
Not great on the quality of the pic, but you can see it on General Hydroponics website.
Might help to be using the right formula for this stage.
Spiney, I was wrong! I just watered problem plant and took a good run-off sample. I’m at 1 EC! Not even close. Just ordered my Floranova bloom. We’ll see what happens. Thank you for your advice, really appreciate it.
PH at 6.9, will get it lower.
Thats not bad really. Not for soil.
