Drooping leaves, growth slowed

One of my plants started showing drooping leaves about 4 days ago and I figured she got too much water. I let it dry out and cut back on the amount of water I was giving them. Now all the plants are showing the same symptoms and before I cut back on the feeding amount I wanted to check with you guys to see what you think.

Strains:

Northern Lights Autoflower

OG Kush Autoflower

Plants are 3.5 weeks from sprout

Medium is promix organic premium blend (soil)

Watering with nutrients every 2 days seems to be when the soil is dry up to the knuckles

General hydroponics flora series nutrients
5 ml CalMag/ 2 gallon
2.5 ml Micro/ 2 gallon
2.5 ml Gro/ 2 gallon
1.25 ml Bloom/ 2 gallon

PH is 6.5

Ppm 400

20/4 light schedule mars hydro tsl 2000 about 20" from canopy.

I started to LST them less than a week ago and shortly after that is when the first plant started showing drooping leaves, so I've since taken all the string off in hopes they just grow and don't die on me.

Doesn't that Pro Mix have slow release ferts already? Probably better to just try watering less frequently and without the ferts. Sorry, im not an expert either, but from what ive been reading, droopy plants can be both under OR over watering. Hopefully someone more experienced can help lol

Yeah you're right they do have slow release but it was such a small amount I figured after 3 weeks most of it would be flushed out. Couple people on other forums recommended giving straight up water (ph balanced of course) and bottom feeding thru the Trays. Probably going to start with that and see what happens. It's my first Indoor Grow so I wasn't expecting to grow anything to write home about more of a learning experience.

Don't worry bro, im on my first run and already Effed up MULTIPLE times lol learned so much already though. Luckily, I was able to chill out and take a step back and solved a lot by not panicking.

They look over watered and over fed.

Quit giving nutes.
How big are your pots?

When I grew in soil I used 3gal fabric pots (autos also), I only had to water every other day right @ the end of flower.


Your pot should be light as a feather before you water each time.

Same size 3 gallon fabric pots

I'd suggest next time you're @ the grocery store, grab some bamboo skewers. They're long enough to reach the bottom of the pots. Jab those in to check. All the way down. They'll let you know if its dry or not until you get the hang of knowing when to water by picking them up.

Shouldn't take more than a week.

As far as nutes, I'd lay off a couple weeks, then go back full strength. Maybe a little sooner if they show signs of deficiency.

I use this to help diagnose mine.

Best of luck.

Considering they're in a soil medium and you're feeding them frequently, the plants could be experiencing nutrient lockout. This happens when mineral salts build up in the soil, which prevents the root from uptaking nutrients.

I recommend holding off on nutes and flushing with water.

PS: You probably don't need to use CalMag at all unless the plants are showing specific signs of deficiency. It's only really needed in coco/hydro grows.

You said 20" away from a TSLMars 2000? Sounds close to me. Go 30+" inches for awhile, they look worn out. Go closer when flowering though. Just how I do it, your results may vary.

Thanks for all the help. Much appreciated.

Seems like the consensus is hold off on nutes use ph water for next couple weeks and I will try raising the light back to what it was around the seedling stage... Thanks everyone for ur input.

Just an update few days later, two of the plants have rebounded very well. The third is looking better but still not there yet. I have raised the light to over 20" stopped all nutrients for the last two watering and I have been bottom feeding them trough the pans.

Just wondering if the yellowing leaves on the bottom is normal? From the chart posted earlier looks like mobile nutrient defeciency, but not 100% sure.

Do you guys think they are ready for nutrients yet or should I hold off on another feeding? They were last watered this morning, so another 3 days they will be ready for their next watering.
