    Yellowing new growth after switch

    This is my 2nd grow indoors. I have a 4x4 tent with a viparspectra xs1500. A 6in infinity exhaust. I am growing 2 clones i clipped april 1st from my first grow. Gorilla breath feminized. They both are in a 7 or 8 g planter. before i transplanted them i had the tops tied down thinking i was going to try scrog but i left them up after transplant. Right before i switched them over i thought i got them used to the new light. And they loved it and started seeing that they were females And i put them in 24hour darkness. When they came out they were yellow on the new growth. Its got better after 12 light. But after the 12 dark the new growth is ight again are they ok? Is that normal. Ya see anything it would be appreciated. My 1st grow sucked. Hoping to make a good grow his time.i did a light flush it helped i think. The e.c. was at 1.8. The ph is 6.5 using fox farms ocean soil. I have the light at 20 inchs getting 850ppfd at 80% power . the temp is 78f and 60% humidity.

      Looks real good to me. Growing that much a day is a good sign. Keep up the good work!!

    New growth is often a light green and is nothing to be worried about. If the green turns to yellow then you do have an issue, possibly ph issue or not enough nitrogen. But looking at your pics i see nothing to be worried about.

        I moved my dehumidifier out of the tent and put it in the darkroom the tent is in and that did wonders. I ended up getting a new PH tester and it came with a soil PH probe as well. and if its right, the ph is closer to 7 than 6. My old PH tester messed up and i have been using the drops.

                      Your plant looks good but I honestly wouldn't trust that pH soil probe. They are notoriously inaccurate.
