Yellow leaves, red discoloration on couple of branches

1st plant-day 37
2nd plant-day 36
In both cases, the first leaves turn yellow at the very bottom. They are to be cut after 60 days. On two plants, red discoloration appear on some branches. Both are higher than in the manufacturer's description. Is everything ok so far?

Autos or Photos? Soil? Coco? Nutrients used? Need a lot more info.

Offhand, i'd say they need a vegging feed-more nitrogen. The pots look pretty small too. And lastly-very , very few plants will be ready at 60 days. I know some seed breeders claim they are, but it's usually a "best case "scenario. Harvesting at 60 days will leave you with half the yield you could expect and the quality will not be great.

Two plants are automatic feminized. I used so far 3x Bio-Grow (BioBizz) and in last days 1x Top-Max+Bio-Bloom (BioBizz). Doses according to the manufacturer's recommendations every second watering.

*Potted Soil: BioBizz Light-Mix
*Flowerpots: 9L (1st) and 7L (2nd)
*Lighting: COB LED Citizen CLU048, color 3500k, 100W (currently set to 60-70W), set to 38 cm from the plants
*Temperature: 22-23 degrees.
*Humidity: 60-80%
*Watering: pH was checked before watering (using GHE test). It came out 6.2.

I'd turn the light to full. The are stretching up quite a bit and are starting to flower, so they should easily take a 100w LED now. And try giving them a boost of nitrogen. I always find i need a lot of nitrogen when i use bio bizz lightmix

I'd say they look fine and well fed mate, probably just the lack of light reaching the bottom leaves so they will die of naturally, as above though, get that light turned up, looking very well for there age good luck

Hello.

I think my plants have a phosphorus deficiency. The problem came up a good few days ago. But I thought it was natural for the plant to get rid of the lower, unnecessary leaves. However, violet stems started to appear near the leaves and more and more of the lower leaves are dying (there are not many of them, but their number is increasing). They were watered less than 48 hours ago with only water. It's not time for another watering, they still have water. I am afraid that I will give them too much water. Should I water or wait?
