Turning a little yellow

All 4 of my plants seem to be doing there own thing. They were all germinated within a few days of each other, all white widow autos. Not sure how harvest and dry is going to work since I don’t think they will all finish at the same time now. But the question. The first picture is one that has started loosing it green and turning a little yellow. Is this normal for a couple weeks into flowing or is it a sign of something missing?

Just the others…

Looks over watered to me.

Fox Farm, right now they are getting about a liter of water every 2-3 days depending on weight, finger test and moisture meter. I’ve switched to bloom nutrients so I was leaning toward lack of nitrogen. But I figured I better check with the professionals first.

Nitrogen is really important in early flowering when the plant is stretching. Growth in early flowering is significant (a plant can double in size during the stretch.) Stretching usually slows down about the 5th week of flowering when the plant will stop vegetative growth and start focusing on ripening flower.


Hey @whtdrgn the first one is into flower and could use a bit of the shade leaves plucked to me. Even the sisters might do well to pluck a few. I wouldn’t take a lot of shade leaves but the yellow ones and the some lower shade leaves you could do without. Try and open up light to the middle that are cover up bud sites. Best to pluck them right before lights out.
If you can post your feeding schedule alone with nutrient line you are using.
Also lighting specs such as fixture and height from canopy.
I have a couple of GSC xtreme that are a bit different in color once they get into the last few weeks of flower. One gets a bit more purple colors in canopy leaves and bud structure.
I grew the two mothers earlier today his winter and now I have five clones from them and they are looking the same as moms.
If you are into flower feed you should be cutting nitrogen a bit and raising phosphorus leaves. But I don’t cut nitrogen out completely until the last three weeks of flower.

What size pots are they in?

@Dforce 3 gallon fabric pots.

When you water do they purk up? if so they would be under water. Under water an over water look almost the same. As @MidwestGuy said nitrogen is important in the beginning of flower, but needs to slowed down after stretch. Might want to water to 15 to 20% runoff.
Do you know how long they have been flowering? If so, mix nutrients as required, unless your using Jacks.

@LateNightGardner hope I get all your questions. 2000w led at 18 inches with a dli of 56. Plants have been taking a little over a liter each every 2-3 days.

Veg nutrients where 12-4-8, stopped a little over a week ago.

Bloom nutrients at 5-25-5.

@Dforce When they were in full vegetation mode a perk after watering was noticeable but over the last couple weeks I would say no I don’t notice any change when watering. Love the camera feed from inside the tent.


Maybe @Borderryan22 or @merlin44 may be able to throw something else out, but sure looks like a watering issue to me.

I agree with the others, nitrogen plus possible watering issue. This could all happen it your pH is out of range as well.

These excellent growers have given great advice.

@Dforce watering issues, anything is possible. I check the weight as best I can with a full tent, check dirt with my finger and jab a moisture meter in for good measure. PH is as close to 6.5 on the water as possible. I don’t have a soil ph tester.

My set up is very similar and with 3 gallon fabric pots I only water every 4 to 5 days when they actually start to droop and the bag is very light.

My opinion is based on you saying they are always drooping and you water every 2 to 3 days…and with the same set up again, I think they are being over watered.

I like the “pick the bag up” method. Wait until it is very light. They can feel dry to the nuckle but still hold lots of water at the bottom.

They need the FULL saturated to bone dry cycle. I have even done the “wait till they droop again” method of watering. That way you know for sure they are screaming for water. They rebound very quickly each time.

Good luck!


@whtdrgn Clean up the bottom and get more air flow she will straighten right up

Thanks @Dforce for the tag. I think it’s kinda been dialed in on watering and nitrogen. The lighter yellow is a big indicator, and is usually followed by blemishes that turn into spots. Once nitrogen is too low, then potassium and phosphorus start lacking because they aren’t carried where they need to go.

Also, they are in flower and taking in more water than they did in veg. In 3 gallon bags with soil, a liter may not be enough. You want a good runoff of about 20% what you put in. Let them dry an extra day, and try 2 liters. I imagine 1 liter in 3 gallons hasn’t given much runoff.

With everyone comment and suggestions I think im going to try the extra dry day followed by 2 liters and see how that goes in a week or so. Thank you all for the suggestion and pointers.


Im sort of leaning towards a start of a iron def maybe

Update. Made several changes that seem to have made them a little happier.

Watering, force a 4 days watering schedule with 10-20% runoff which bumped the amount of water to about 4 liters per plant. Good solid drying out period followed by a complete soaking.

Water, I stopped using ph balanced filtered tap water and switch over to store bought distilled drinking water.

I also cut the nuts in half. With the added amount of water it was the same amount but twice the water so half the strength.

Keeping an eye on the tricomes now but that’s another topic. Thank you all for the pointers. First grow, can’t wait to see how the next one turns out with everything I’ve learned.
