Hi this is my 1st time growing autoflower , so far I’ve found it a struggle to keep them happy
3 plants in an 80x80x1.6 with a vipahspectra xs2000 light that hangs around 12-20” above canopy.
Day time temps around 25-27 night time around 19-20 .
Using advanced nutrients at half strength,
Soil is bio bizz all mix , in 3 gallon pots
I PH to around 6.5
Here are some pics there so yellow .
Any feed back welcome

"This heavily pre-fertilized substrate mixture emulates a rich outdoor soil with a full micro active ecosystem. It’s been designed to have enough nutrient-fuelled power to sustain lush growth for a couple of weeks, without any need to add any extra fertilizer."

Why are you using what can be described as a nutrient line designed for hydroponics in a pre fertilized soil? Don't do that and expect excellent results, you messed up something chemically in the soil. Even at half strength, something bonded with something and locked it out or washed out those nutrients every time you watered because suddenly the nute was mobile when before it wasn't.
Now i have dosed my soil grows in late flower with General Hydroponics once or twice for a feed boost but you shouldn't do it often, much less during the entire grow. In my opinion you should pick a growing medium/style and learn it and stick with it. There's just too much science being mixed if you looked deeper into why using hydroponic nutrients in soil isn't ideal.

i dont recommend stuff like that. that's for each grower to discover for themselves, and what best suits them. too many things to consider, such as space, spare time available, money, etc. I just try to find what's wrong and how to avoid it in the future. If your lifestyle is highly active and you cant spend a lot of time around the plants, then soil is better. If you can spend lots of time around the plants, DWC, coco coir, or hempy is good.

I use soiless but still treat as soil but feed each watering. Dont like true soil! So is hydroponic but in medium no? I alway hear ppl refer to promix as soil. Not sure why?

i'd call it a potting mix....to me promix is soil without nutes, potting mix. you have to add something, but since there's nothing in it you can use it as a soiless. imo, you're not breaking any rules. i wouldn't call it hydroponic tho, unless you have an airstone running in it. I think that's more like Drain to Waste what you're doing

Lots of white pistils, still weeks away from being done in my opinion. If you're trying to rush because of the yellowing, there's no need. That plant is healthy enough to go the distance.

Not sure if you settled on nutes in the end, but the Bio Bizz line is a great match if using All Mix soil. Might as well go all organic.

Oh, and don't flush. It doesn't have any positive benefits when A/B tested against non flushed weed, plus the plants are still putting on weight in those last weeks and can use the nutrients.
