Growmies.. I’ve missed you all! I’m on my third grow. 1st was amazing with your help! 2nd was horrible I tried not to bug yall.

The two in the back are Skywalker OG the one up front is cookies. I’m using Fox Farms from the ocean soil. I just started my first round of nutes and topped the back right plant ,As it was growing super quick. I’m running about 60% humidity and 75 to 80° ---

Watch the PH on the FF soil, it’s known for low ph, and I would throw that meter in the pic away, they are notoriously inaccurate! Make sure your runoff is in line, with a good meter. 👊 What is your water/feed schedule now? And don’t worry about bugging us, that’s why we’re here! Lots of great growers here willing to help anyone who needs it!👍😉 ---

@Growdoc Thank you sir! I will trash that meter.. I do have a PH tester to test run off. I will do that next water..thanks for the heads up. I have used Roots organic for the last 2 and I do not belive I had these issues this early. THANK YOU AGAIN! ---

@Growdoc every 3 days and every other.. this was my first feed. All im using right now is FF big bloom. 3 tsp/gal vs 6 recomended. ---

Looking good! I’d recommend getting a ppfd or quantum light meter, setting your plant to the correct light intensity will ultimately help the plant; guessing by % of a turn if a knob you could be depriving them. Using a dli chart and setting your plants DLi to it’s stage will maximize your plants efficiency. Edit: remember a lux meter is checking color not photons and light intensity; they can and have been used, but are a tool for interior designers. I hope you have a wonderful weekend! ---

Looks to me they may be getting a bit too much light or are nutetrient locked with how pale they are. Test your output ph at least and if it’s below 6 I’d try and use some ph 8 water to help get it up without completely shocking them. ---

Yeah I think you guys are right looks like we’re about 5.6 on ph runoff. I increase the pH in the watering today and increased the lighting a little. Thanks growmies I appreciate your advice! ---

At one point I did have the lighting up which I believe was way too high like 75% I dropped it down to 60% ---

@Growmoredank , @Cosmoctopus , @OldNailPounder Afternoon grosephs! They’re not doing much better, is the ph and I’m staying away from nutes right now. Maybe my lights up too high I’ve got it at 50%. Temps are at 78° Max 55-60% humidity Water every 3 days. 18/6 light light is at 14 in above canopy. ---

Not this last watering I checked the water prior to watering it and it was in the blue which was a little high pH. ---

You’ll need a ppm meter. A pH meter would be more accurate than test swap strips. ---

It’s almost certainly a pH issue now, you would see more damage on the top leaves than the bottom ones if it was light issues. Definitely look into a pH meter and not test strips. Also look into CalMag as it helps the other nutrients flow better. ---
