Any advice is much appreciated, thanks in advance, leaves started getting brown spots and slight curling down in places, seems to have started with one plant and is spreading, I feed with green planet 3 part, plus calmag and ph to 6.2, was using a 600 watt cool tube for veg, switched to my 1000 watt flower light and kept the 18 hour days to let them stretch before switching to 12 hours, this started shortly after, I have 5 purple urples and 4 blue dreams in 3 gallon smart pots with mother earth coco, let me no what other info is needed and thanks, I'm sure I'm overthinking the problem myself, I already flushed 4 gallons of water thru each plant a week ago
Need help diagnosing plants

So you washed out all its food and the Ca/Mg that the coco needed.So you need to get it all back in there.Nevver feed straight water your starving them.

Ryan...what Myke said here...is what you should be doing. You may have washed out some of your coco calmag buffering too...so I suggest that you add back in a full dose of calmag with each watering or flushing. Is your RH too low?

I'd flip them to 12/12 now. Why isn't your air cooled hood hooked up to your carbon filter's ducting?
I run my pH from about 5.6 and not over 6.01. I shoot for 5.8. I feed and water mine every day to some run off. I don't bother checking my ppms or pH on my run off. Every two weeks I flush my plants to significant run off then feed them the next day. So every 2 weeks my plants go one day without food. But water every day.
Good luck

Thanks curious, this is my first time on coco. Always used fox farm ocean forest, I think I didnt pay attention to proper feeding schedule and technique, I'm not using the carbon filter because there's not much smell yet and I was waiting until their healthy looking again to flip, I'm anxious to flip so I will soon if yall think it's a good time and wont hurt me

Keeping in mind a doubling in bloom...flip them when half as tall as you want them.

Just curios, why would you do that?.. keep and 18 schedule after changing to HPS? They prob won't stretch until you go to 12/12.
I was told the change of spectrum would cause the stretch before I go into flower and the plants would be happier in flower if I did it before hand, I'm starting to think it might have been bad advice if I do get alot of stretch because my net has really filled in since I changed

What's your watering /feeding schedule?
How do you check to see if they need water?
What week are the plants in?

What's the point of having that net in there if the plants are just going to grow straight up through it? You're supposed to use the screen/netting to train plants for one level canopy. I keep seeing photos of people growing with a net that's basically doing nothing as if people see someone growing SCROG style and just throw some netting in because they saw it in someone else's grow.

I use netting to hold plants up, sometimes the colas get so heavy theyll fall over if I don't. I understand where your coming from though, it's likeWhat's the point of having that net in there if the plants are just going to grow straight up through it?
