I think the plants are overwatered starting with the flushes stayed in the beginning and have consistently been overwatered since.
Also 58 degrees ambient can be even colder at the roots and is too low to sustain good health. The roots are cold and too wet I believe.
I never ph buffered potting soil. The lime or oyster shell in the medium will buffer any decent tap water. So there may be too much acid (ph down) building up which eventually lowers the soil ph over time.
The most important factor in ph’ing Or mixing down with filtered water is to know the source water alkalinity. Too hard will slowly raise ph and eventually block roots. To acidic and it will also lock out nute uptake.
Overwatering crossed my mind. The initial flush keeps the soil saturated for quite sometime considering the clones going into 3 gallon pots and the roots contained to the rock wool at first. I read somewhere that the soil can draw moisture out of the rock wool and that it can dry it out rather quickly. My thinking was to only add a little bit of water (2.5 cups on day three) to moisten the rock wool knowing the soil was most likely still saturated. I'm used to watering outdoors with 5 gallon jugs once per week, so 2.5 cups seemed like only a little bit. However it may have still been too much. On Day 6 I tried moistening the rock wool again. This time I decided to try less, 1.5 cups, because I was waiting for some supplies to be delivered the following day for the next watering. I was concerned with the leaves drying out thinking they weren't getting enough water, or they were nutrient deficient. I probably made every mistake imaginable in the beginning regarding the watering schedule. I'm trying to figure out the right amount to get on a three day watering schedule. Also, I won't be flushing so hardcore in the beginning next go around. The soil I'm using was nearly bone dry. I have bags of it I purchased in July. It's a custom mix from the hydro store I go to. However next time, I'll most likely just pre-moisten it in a tub and then fill the pots with it.
Since indoor and the set up is brand new to me, it took me about a week or so to work through the internal conditions. I think I have finally solved that issue. The temps should be maintained in the high 60's-70's moving forward. Just one of many hurdles I've had to overcome. It's definitely a process and a reality check. I thought I had a great plan and was going to kill it on my first indoor grow. But this has been a bitter/sweet experience so far only 12 days in. Getting the plants healthy and strong has been an uphill battle I'm still fighting. Live and learn I guess.
She has been stressed a bit.
1. Ph, soil shoot for 6.3
2. Keep her dryer, she looks drenched
3. Air flow, increase intake air as your lights are very powerful for plants at this stage. Bring in more co2 Loaded air or add co2.
4. May wanna uppot or reppot as lockoout symptoms are showing.
5. And great log, love it when the logs are so clean and it’s easy to diagnose from.
I’ve never used rockwool and guess I can see how it could clash with the soil moisture. Don’t know how to advise on that.
The plants can recover. Let them dry out real good. I use a moisture meter and can tell by weight now but the meter will read in the dry zone 3/4 the way down the pot before I see the plant need water in ocean forest with perlite added. Worked good for pro mix too at that dryness.
I disagree with trying to transplant deficient stressed plants. It never worked out too well for me anyway.
I would always try to stabilize the situation at hand before transplanting or flowering.
Also maybe next time start plants in party cups or 1 gallon pots. You can saturate them to runoff and simply wait for them to dry. Even if it’s a week for the tiny plants. The roots will search out moisture and nutrients more through the drier soil and fill the entire pot with roots. Then transplant up and do it again.
Way harder to overwater the proper sized pot.
