What’s up DGC! My past 2 runs I’ve noticed quite a bit of yellow in the new growth after I switch to flower. I guess I attribute this to the extra growth as it stretches, but I’m wondering if there’s a way to keep them a little greener at this phase. Everything seems to turn out fine once buds form, but I want to make sure they’re getting everything they need. I am using organic soil with R.O. Water so I thought it could possibly be cal, mag, or iron deficient but I’m not sure. Is this a normal amount of yellowing during the plants stretch phase? Or would a boost of nitrogen possibly help before the flip to help it through the stretch? I tried some foliage cal-mag plus iron on the first run but I didn’t notice much effect. Soil is fox farm with earthworm castings, malibu compost, and some down to earth rose and flower mix. I water in occasional compost extracts, Recharge and silicic acid.
New growth is often light green. If the new growth yellows from necrosis, it’s from unavailable trace elements like iron, boron and zinc.
Exactly what you said, rapid growth phase “the stretch.”
Though, that’s a little more yellow in the center than I like to see, so I see your concern. Try mixing in some tap water with the RO for those trace minerals.
I don’t have any insight on that, but if I we’re going to try it I would get my ppm to 60-80 and watch for a change then adjust up if no change.
Totally with Coach and jmystro, I noticed you mentioned Down to Earth…I use Bio fish (7/7/2) with unsulphured Molasses water ins (3tbsp per g)… and the addition of this WITH a correct ph smoothed the transition out a bit. Growers ❤ from AZ.
Thanks I’ll look into the fish. I might need to lower my ph a bit. What is the reasoning behind the molasses? Would increasing carbs help the plant build structure a little faster? I have some molasses but I’ve backed off in my extracts since I heard it can throw off bacterial populations and attract bugs. But if the plant can use it I’ll give it.
Very common thing you’re witnessing. If you think they can feed more, try it on just one. Don’t risk a whole crop that’s been working out just to get a little more. Good luck.

Thanks guys I guess if they’re happy and praying I’ll just leave them be. Next time Maybe I’ll feed right before and see if that helps
I’m sure your soil mix has enough nutrition. I’d be checking to see if the soil has gone alkaline somehow. Make sure your soil’s pH is below 7. Those trace elements are not very available above 7.
Got you! You might be on to it there. Ph is right at 7 I’ll try getting things a little more balanced before flip next time.
