Since it’s so early in your nutrient regimen, I can only suggest it might be a magnesium or potassium deficiency I could be wrong since it’s too early to tell just yet @Buds007
The looks like heat stress and the light too close too me. @Countryboyjvd1971 Put another set of eyes on that pic for me, please
But while we are here, this was from 10 days ago. Is this still accurate?
Why are you pHing to 6.5?
I believe I asked that very question some time back.
Coco should be ph’d to 5.5 and 5.8 @Buds007. You will run into issues sooner than later with 6.5 ph.
@bob31 @Myfriendis410 I have changed to 5.8 as a result of the comments after that support ticket. I was only pHing at 6.5 because I didn’t know that coco was considered hydro & not soil, but that was before I was using any nutrients. Since I’ve started feeding it’s been at 5.8.
Thanks @Countryboyjvd1971, I will do that & post some pics in a few days.
Is that the feeding chart you are using for the cyco nutes?
ok, good to know! That is important! @Buds007
Then I’m going with heat, light stress. How are the temps at the plants?
Do you have one of these? Very handy!
(I have three, lol)
@bob31, yeah but my table is in metric ml/L & there is a couple of extra nutes in my one. I do have one of those in the tent & one outside. Temps are around 20-23 degrees Celsius (68-75F)
Check their website and download the one you want. I only took a screenshot of part of the chart.
They have different charts for different growing mediums amd for US / imperial measures and Metric. I searched cyco feeding schedule or chart and found them. @Buds007
I wound up with an old chart with my FF nutrients so it’s always good to double check!
@Buds007 when you find the feeding schedule for you, measure your nutes using the tds (ppm) numbers instead. You will actually know what your nutrient dose is.
@bob31 @Myfriendis410 the one on my box of nutes is the advanced for hydro (coco/perlite) so I’m all good, although I did print off the latest version in case it’s slightly different. One difference I did notice was that it says to flush with their product called Klense every week, do I need to do that or could I get away with one day of plain pHed water & give them a good soak?
I always check the TDS before I use the nutes, it’s never been more than 50ppm over, I just add a little water to bring it back down & then do the pH.
I have to recommend you follow their recommendations. Once a week seems like a lot, but that would lead me to believe that they want you to alternate feeding and waterings. @Buds007
Thanks @bob31, so do you think I should get some Klense or will just using water be fine?
That’s exactly my thought too, Bob.
I’m a coco user and it is highly recommended to alternate feeding and watering. During veg my schedule is feed water feed water. Around transition I go to a feed feed water cycle. All done with 10-20% runoff. This would reduce the need to flush, especially if you gave them a bit extra once a week. By extra I mean another quart.
I am also using @garrigan65 schedule throughout, of low tds value with GH products. Everything ph’d at 5.8 for feeding and I go to 5.5 for the water to take advantage of the tendency to rise in ph over time. They look great so far.
Update - Day 33
They seem to be perking up since I modified the watering/nutrients regime & have grown a bit, what I’m wondering now is how do I know when these auto girls have started to flower since they are not photo responsive?
You’ll know. They’ll become every more beautiful 1 pistel at a time
