Need some guidance here. All 4 of my plants have a different hue of green. Gg#4 autoflowers Started in happy frog and transplanted to ocean farm 4 weeks ago. Plants are 8 weeks old, been flowering for two weeks.
10 days ago I added nutes at half dosage to all the plants. I know it was a little early then 4 weeks, but I was going out of town. All but one has had yellow leaves and lost some green hue beginning 2 days after
New growth on all but one is green. The smallest one has had the most yellow. Ordered PH pen and ppm pen, but I
have been going in blind. Only fed that one time and the discoloration began two days later. Been watering to 20% runoff every 3-4 days
Any guidance??? I have seen it could be nute toxicity, nitrogen deficiency, cal/mag deficiency and have no clue where to start as is my first grow
The one plant is doing perfect and under the same variables. Thanks for your help
I don’t know anything about autos so take this for what it’s worth. She looks pretty decent overall but a little hungry. What are you feeding?
I fed them the fox farm trio at half dosage and then started noticing the leaves turning yellow or lighter green. Haven’t fed since as I was out of town and didn’t know what was wrong
You think it may be a nitrogen deficiency and they need to feed again?
Like I said, I don’t know much about autos and, I don’t use mineral based nutes. So, I would wait for some more experience eyes for advice on how to proceed. If I was in your shoes, I would get the pH straightened out before I did anything else, if it’s out of line in the root zone, it can lock out specific nutrients and adding more could just cause more problems.
Looks hungry to me too except the curling tips of one plant, looks to be the tallest, closest to the light?
I do some autos but diff nutes. Doesnt look over-fed nor overwatered so thats good. Couple look hungry but the pale especially one I’d wanna know the runoff pH
It is actually the smallest, I don’t know why they are burnt/curling there
I will get a runoff ph as soon as I water again in a couple days
I would think they need full strength at this stage. I would go full dose and just water in between feedings.
Feed, water, feed, water, ect.
Here is the schedule if you dont have one.
This is a dumb question, but of that gallon that mixes how much do you use per plant. The whole gallon on each plant? Thanks in advance
Yes the chart is per plant
Thank you. I’ve been drastically underfeeeding I presume. Checking ph and ppm tomorrow
Check runoff ph and PPM before you do anything… mught be a ph issue that needs corrected.
Use as much on each plant to get approximately 20% of what you put in comes out the bottom (run off). This will help prevent salt accumulating in the root zone.

I got my pen and most of the ph’s were in range; all but one.
Plant 1: (this plant is doing amazing) 6.9 ph and 1110ppm’s
Plant 2 (light green leaves) : 6.49 ph and 911ppm’s
Plant 3 (lots of yellow leaves ): 7.35 and 843 ppms
Plant 4 (yellow and browning leaves) smallest plant by far: 6.65 Ph and 872 ppms
Ok what now, feed and lower that ones ph?

Thoughts after checking runoff numbers above good growmie sirs?
