im growing a blue cheeses auto it is a 95 day autoflower and buds are turning yellow 27 days in to flower and sugar leafs are turning yellow and fan leafs i still got 42 days or less to go is it ok or am i fucked...ph run off is 5.9 and im sure its a little higher so i dont think its ph grouwing in ffof using ff nute line at half dose and when i go higher it burns my plants a little so i backed off on the dose i was giving them a while back, im using 200 w ds im using pure tap water its soft water and i let it sit out, i flush as i fill needed and will fluch in 4 days but when i do flush my plant seams to starve some where she dont need watered but every 4 days

Not sure. I am new to autos. I got one yellowing. What from what I've read autos do that and by time they finish all the fans will be gone with yellow sugar.

they did this same thing not to long ago but they turned back green again I got to flush next watering so i hope that clears it up unless this is normal

What did you do to turn them green again?

I turned off the cfls and flushed then hit them with cal mag, they hate any extra heat it was only 80 to 84 in my room but they taco-ed and wilted ....... I was told when leafs turn yellow they dont turn back but they did

Another solution if you can't lower temps is to add CO2, it makes the plants able to cope with much higher temps.

Nice looking plant.

When asking for help with a problem you should post under Plant problems" and list every detail of the grow including, strain, lights, water source, nutes, soil, etc..

Calmag deficiency is the number one problem I encounter and see on this website. It looks like not enough N, nut these soils have plenty of N. Sometimes too much.

If you are using tap water then switch to 25% tap and 75% bottled water. Supplement with CalMag.

Tap water with high PPM of dissolved salts with really mess with CalMag levels as well as nute efficiency. Also LED lighting will cause CalMag issues. If it's not calmag then it could be PH.

Without knowing all of the details nobody can really help. We just have to guess.

My best guess is that it's the tap water. If you have a PPM pen then let me know the ppm of the tap water. Here is the problem. People on here swear up and down that tap water is just fine to use. The only problem is that everybody's tap water is different. When the PPM of your water out of the tap is high then the calmag gets all messed up. Your nutes and supplements are competing against the dissolved solids already in the water. I gave up on using my tap water as it is 500 ppm. I now use 25% tap and 75% bottled RO or distilled. My problem of yellowing leaves is solved,

Plant with calmag issue even though I was using tap water and adding calmag, When I switched to RO the problem fixed itself.

The end result was horrid. Decent weed, but very low yield. Even look at the size of the fan leaves. They are tiny. The whole grow just completely struggled. I got 2.5 oz from 3 plants under 300w of HPs. That's 70 grams. I should have doubled that at least.

Lesson learned though.
