First time grow; leaves losing their color

[captainkong]

Hey everyone this is my first grow and I don't know what's going wrong, but over the last week my leaves have been going from a green to a light green almost a yellow color.

Im using fox farms soil, watering every other day with a 300 watt vivo sun led light along with a knock off 100 watt light I bought off Amazon. I always water with Reverse Osmosis water and try to keep my humidity at about 70 percent but it seems impossible due to the amount of air flow I have... So really my day time humidity is at 55 per ent. Temps stay at a steady 74 degrees during daytime. I don't know what the temps are at night.

I test the soil and ph of the water regularly. Soil is at 7.0 water ph is around 5-5.5 ph

I want to put these plants into flowering in two weeks but I don't know if that's a good idea at this point.

Any help would be appreciated.

I'd say you're watering too much, the roots need O2 and right now they're drowning and can't pull enough nutrients. Let the soil dry back before watering again, water mostly around the outside of the soil, not in the middle. It's gonna take a couple weeks for them to recover. Also, watering a ph of 5.5 is too low, which may also be part of the problem. PH the nute water/water to about 6.2-6.4. Don't worry about the soil PH.

So you think maybe twice a week water then? Also, should I wait till the plant recovers before putting them in flowering? Or does that not matter?

Thanks!

Yes i would wait now let them recover, flowering puts a big strain on them you want as healthy as they can be. Hey just a suggestion those pots are small enough to pick up and judge the weight of them wet and dry, it's how i do it when i grow in fabric. Good luck and keep us posted on recovery.

 

[captainkong]

Yes they are 3 gallon pots. I was told 3 gallon fabric pots are big enough to grow in. Strain is Sour Diesel.

Turning down the lights 15-20% will help them recover. You're better off lowering light intensity to allow time for the adjustment to take hold. You can turn it back up once the plant's new growth is healthy green in color.

 

[captainkong]

Okay will do. I figured running the lights at 100 percent would be best. I'll turn then down a little bit. I just don't want to lose too much temp. If the temp gets any lower id have to add a heater. And id prefer not to do that.

Thanks again. I'll be sure to post pics on the recovery

I actually learned the “pick up the pot” technique from you. It’s a great method and one I use daily

What are your current temps? To be 100% honest, even in light of the watering issue it still looks like you're trying to use too much light. Yes, too much light is thing. Your foliage should be a lush green color and frequently to achieve that means lowering light intensity. Too much will bleach the leaves.

If you get the Photone App, it’ll help you get your light dialed in.

This is the top cola of my Northern Lights that was getting blasted at over 1,400 PAR before I raised the light. Notice how the color looks pale rather than vibrant?

The photone app is a good idea ... I'd still dim the lights about 15-20% from where they are at right now to aid in their recovery. You always can readjust light intensity once the problem in the foliage is fixed. Don't worry, you'll slow them down more by bleaching their leaves than you will reducing light intensity.

Definitely reduce the light first and let them recover. Then work on dialing it in.

Great suggestions. I dont really need to add anything else but since Im bored I will add additional info
They are indeed overwatered, also burned by the low PH, like phyto said thats dangerously low. At below 6ph aliminum in the soil becomes water soluble, its toxic for you and for your plants, and you probably burned the roots aswell. Perhaps light played a role too but most of the damage is done by the beforementioned because it goes from the bottom to the top of the plants. Still is a good idea to lower it since stressed plants wont be able to process as much light.
What are you feeding?

Have not been using nutes yet. Read that fox farms living soil provides nutrients for at least a month. This is the 3rd time I've transplanted. These were clones I was gifted. Started them off in quart pots moved to gallon sized then a few weeks ago moved them into 3 gallon fabric pots. I thought light burn was an issue so I moved my lights from the previous distance of 14 inches to the current distance of 21 inches.

You've got all the right answers here already while I was typing out my long winded response! Lol

@Phyto knocked it out of the park!

 

[Eledin]

Hmm if they were so close yes, I can also see now that the tops are slightly more yellow too but the bottoms are still burned. If you transplanted 3 times its hard to keep track of feeding needs but I reckon that if you transplated 3 weeks ago into fox farms soil they should still have nutes.

 

[Eledin]

But that will highly depend on how much new substrate was added too. As I said, its better to keep it simple, 1 transplant.

 

[Eledin]

Since you are not feeding anything as of now and its completely impossible to know if they are hungry because of all of the yellowing, do you have any kelp by any chance? Or something rich in aminoacids to help your roots? Aminoacids are key for root growth and health and kelp also contains vitamins helpful for your plant, overall a very good thing to add if your plants are struggling.

I would still read it the more people the merrier.
