Question. Sorry to “hijack” your post. I can not find the new topic or the button to create a new post on my new OnePlus 11 android.
I have two autoflowers that are 7weeks old in a grow tent. KittleZ and Brooklyn sunshine. I have 3 gallon fabric pots and I noticed the one the rights. Leaves started to droop. Now some of the leaves are changing a yellow color. I started fox farm nutrients from an schedule I found here that is similar to the one fox farms has out. I used Evian water at first, but switched to crystal geyser. It’s my first grow. I have 2 100w led lights. I’m giving them nutrients 2 days a week. If my meter says soil is dry, I sometimes will give the plant a little reg water. I wasn’t sure if I possibly could be giving them too much water or too little water. When I feed them, I give each one about 1/2 gallon of water. 2 days ago I was worried about them and flushed them with sledge hammer. I haven’t fed or watered them again as they are still moist.
Any suggestions?
That’s too often for soil my friend. Soil needs a dry cycle for the roots to have oxygen. I recommend a drench to dry cycle and toss that moisture meter. The FF trio is heavy in salts and when feeding this make sure to get liberal run off from the bottom of the pot, the run off helps rinse those salts that have accumulated in the root zone. I would suggest a water only feed at 6.5 and test the run off PPMs and PH and target and try to maintain 1000 PPMs and a PH of 6.5 through harvest. With 3 gallon vessels I would assume it’s a water or feed day every 3-4 days

Thank you so much . It definitely makes sense. I was so worried about over watering, I didn’t water till I got drain off. I know evian is 6.5ish I tested the crystal water drainage I’ve been using after the flush and it was 7.8. so I did the flush about 3 days ago now and had plenty of drainage. I didn’t re feed. When would you suggest I put a better P.H water in with nutrients again. Should I let it dry out a little or should I refeed and then let it dry out betterment. I have shitty city water and no r.o system yet. The Evian was great but pricey. I read so much stuff, it gets confusing m any bottle rod water you suggest? Awuafeena I think is 5.5 and I can adjust. I also read something about distilled water if your feeding on your own. I have the FF trio, calmag and another FF trio of powder that I would have to check when I get home of its name. Again thank you for your response and any suggestion on the best way to get it back going would be appreciated. Not sure when to feed next.

Btw this is the schedule I was trying to follow (lol). The bottom part someone labeled my schedule. Found it in another forum post on here from someone who went through the process with good results. I guess it’s FF’s vs what they suggested.
What was the run off PH and PPMs? I would be targeting 6.5 for the input unless you’re high or low and trying to adjust. The run off PH will tell us what the PH is around the root zone, the run off PPMs will tell how much nutrients are available or if there’s a salt build up
I wasn’t giving them enough water to even get drainage. I was scared to overwater. I couldn’t reply yesterday because new username limits. Sorry.
I did some testing last night on just the water and it was way too high 7.8. I got distilled water and mixed in my nutes and I think I understand. I recalibrated everything etc. I’ll make sure I get readings from now on
Im using FF 70/30 happy frog and ocean forest anyway how many ppms should I get the first run off test i will do at 4 weeks

Start nutrients once the run off PPMs dop to 900-1000 and keep those as target feed numbers going forward

Ill do exactly that thank you

You’re using all 3 of the FF trio correct? When I grew in soil I used a drench to drought routine on water or feed days. I write down the run off PH and PPMs in a note book for reference. If the run off PH was in the acceptable range of 6.3-6.8 , I would adjust that up or down shooting for 6.5 on the next round. If the run off PPMs were in an acceptable range of 900-1200 I wrote those down and adjusted the next round keeping 1000 as the target. Anything 1300 and over would be a water only day at a PH of 6.5. Feed or water to liberal run off each time, this will help keep a healthy root zone by rinsing away any salt that has accumulated in the root zone. When salt accumulates in the root zone from synthetic nutrients it’ll drive up the PPMs and tank the PH preventing nutrient uptake. This can be corrected with a flush to bring these 2 back in range. Fox Farm also recommends a flush using sledgehammer but can often be avoided using liberal run off

Sounds good, yes the trio and also have 3 powders from FF. Forgot the names, but 2 of them just started (I remember one named open sesame)! I did a flush before my original post with sledge hammer when I first noticed the problem. I waited till wed 4.5 days till dry and used distilled water and the nutes. I’m hoping these yellow leaves come back. Then buds still look good… when you have an issue like this and correct it how long does it usually take for everything to resolve itself?

Issues caught early can recovery with a few days. Seriously damaged leaves will never recovery but most importantly is resetting and getting medium the and root zone back on point. Run off numbers are the easiest way to track what’s going on below the surface
Awesome… you have helped me so much. I surely appreciate you taking the time to do so. I’ll be watering etc in another 2 or 3 days and will have new numbers to work with. Hopefully all perfect I also forgot I recently removed a couple leaves that were buried and probably should have just left them. Wonder if they affected the other leave on the branch. The buds and most leaves look good. It’s just a few yellow ones. I did plant late and tent is in my garage, so temp does fluctuate. Will see. First grow. Trying to learn for the next one

You can remove those leaves, the bad ones will never recover. It’s common for lower fan leaves to yellow and die off, the concern would be the middle and upper yellowing leaves. This could be related to PH or a low or high PPM reading from the medium. A low PPM reading reflects a nutrient deficiency, a high PPM reading above 1500 in soil can tank the PH preventing nutrient absorption. Best practice is run off numbers or a slurry test to see the amount of nutrients in the medium
