i have 2 autos, 150w lamp(a bit low i know) i use biobizz fertilizers, and my plant after they got in flower, it wll went down, they were super good in veg, lots of leaves, 9 point leaves, stocky and bulky, then, they became pale, stopped growing, and started yellowing and also, they started about 4 days ago, in the space between veins in the leaves, even normal ones, not yellow, healthy i mean, to go a dark purple, down you can see some photos, they are 5 or 6 weeks, i have a bad memory xD

Deficiencies of some nutrients, e.g., magnesium or phosphorus, can cause purple color.

Caused by your watering practices and/or environmental parameters.

Some information on the equipment, media, watering practices and environment would go a long way

temp: day 23-27(celsius) in hot days, night between 18 and 20 humidity: 42-60% in the day, and up to 70 at night
media used: biobizz all mix and watering by weight, sry plant between 1 to 1.2 kg, water till runoff and to 1.6 kg feeding once a week a bit more maybe max 3 times a week, i apply some foliar magnesium spray, and i use tap water so calcium should be ok, but the ph im sure not so im going to buy stabilized ph water 6.3/4 i think i am to a 7 or bit higher whit tap water

That looks good so they are either drying back too much or not enough. How many gal pot?

Are you adding nutrients or does that soil contain nutrients?

The pots should be filled to the top to aod with watering and nutrient availability if its organic soil. have a read here to help you understand the principles behind watering and a moisture meter may solve your issue.

All mix has time release nutrients that last for roughly 4 week and also a ph buffer when this runs out problems like this happen from ph being out of range a good water with ph balanced water will bring this back in range but then you need to add nutrient as the nutrient in the soil has depleted can do this by ph adjusting ur nutrient mix Happy growing

thanks for the suggestions man, i use metric so i don't know how many gal nor liters ahahah, they are 22x22 cm and they are a quarter short to be filled, i didn't have much soil, yesterday i lifted the plant out of the pot, roots at least from the sides and bottom are looking healthy, very white and no strange colors, yes its a pre fertilized soil rated to support up to 3 weeks without nutes, and it looked a bit, just barely moist in the bottom middle, so today im going to water, but my concern and my prediction is that i use tap water and the ph is too high, i lost my ph papers, stupid me, but my prediction are wrong ph, and bad watering practices, tell me what you think

im sure I found the problem, I watered yesterday and today other fan leaves started turning yellow and the plant became droopy, I'm sure I'm giving them too much water at a time, I'm going to first, buy pH stable water, then water less at a time, I'm only watering them max 3 times a week, also I feed them only once a week so its not an overdosing nutes, I'm giving them less than the recommended by the chart, but I'm not an expert by any means xD
it's strange because I'm not doing anything different than the last year, but this year they seem much more delicate
also they seem really slowed by this, I can't see any substantial growth, bud size and overhaul plant size, also yellow leaves are becoming red between the veins of the leaf, but the strain(lsd auto) has a tendency to go red

looking at the pic the soil looks kinda dry when watering make sure to cover the full medium and allow water to drain through the pots causing runoff do this with 6.4 phed water then letting the medium dry fully and so on overwatering happens from to much water to often if water is draining from the pot overwatering wont be an issue

9x out of 10 when u see this ph is out of range in the medium

Sometimes it's not about "the one thing". It can be a combination of things too......it's possible to have a Ph problem and a nutrients problem, or a watering problem and the light is too close. Or, problem A can lead to problem B....

As someone who finally got to try a couple of Autos, well, I've learned to almost immediately hate them. The only place for them, imo.....is outdoors in a northen (or very southern) area. Maybe if they were designed well (most aren't) and they were the only things someone ran, giving them exactly what their specific needs are.......then maybe they'd be worth it. If any seed company offers to literally pay me to run Autos I would cut off all contact and move.....
