Lime Green/Yellow in only top leaves, excellent desc. w/ pic

This is a Jack Herer, almost a month old. 8-9 Inches. Watered every other day same time with a 3-2-4 Pure Blend. Humidity about 28-35 stable and temp around 75-80. Light is 14 inches away with a 400 HPS Red/Orange Hue Lamp.

Only the top leaves have this color and the plant is still growing quickly and sprouting new branches and full leaves. No wilting or anything else noticeably wrong but want to know if this is the sign of something else coming.

My water is always sat for 24 for my watering and humidifier.

Please let me know what you think.

Are you keeping an eye on the pH?
What is the pH?

3-2-4 nutrients doesn't seem like a veg nute solution to me.
I could be wrong though, any more info on that?

Do a full flush and they will "get their green back".. I can't tell you the exact reason when plants do this sometimes but once and a while when I transplant cuttings they do this, do a lite flush and they will be fine. I think has something to do with oxygen and roots but haven't figured out the exact reason why. But flushing ALWAYS works.. And after you flush feed with have strength and don't feed again till your soil is completely dry

My ph levels should be fine, I don't have hard water and I sit it for 24 at least. Water is usually around high 6-7. And I'm going to flush shortly, does it matter how many holes are in the bottom of my bucket? I'm about to go to town to make sure drainage is great. My soil is close to 60-40 with Potting and Verm. Maybe 60-30 with the top soil included, so 60-30-10.

As long as water can come out the bottoms your fine, but i'm willing to bet that she will recover after the flush.. At what rate are you actually feeding them and not just watering them?

I feed them every day I water them. I tried following the nutrient solution directions which recommended this. It is the Pure Blend Pro Grow for vegetative growth 3-2-4. Maybe watering every other day is too much? Or how do you feel about the feeding schedule?

And my PPM is between 800-900

Your overfeeding, do the flush then only feed with food in your water every 2nd to 3rd watering.. The flush will take care of that then wait for the soil to completely dry out, then water with plain water, let completely dry out and then feed with the next watering. You can water your plants all you want when then need it, but you just can't add food to the water every time you water.

You know that the perfect pH range for cannabis in hydro is 5.5 - 6.1 (some say 6.2).

If you don't have pH-Perfect nutes I would suggest keeping yor plants in that range.

I am using soil.

come on people seriously why are you guys constantly trying to change the ph. guess what your efforts are in vein cause ph flux is bad it causes more harm then good(think nute lockout) imo. keep your ppm between 900-1500 for best results, your leaves will get big! FAST!
