Sad plants. Any help is appreciated!

That’s called tacoing. Comes from heat or light stress . Sometimes over feeding will do it, broad mites will make them roll up too!

I'll try to remember that. I'm pretty good at learning after I've made a fool of myself, lol.

Damn, I got the 100 Watt of that light and I have it at 50 percent and 30 inches above. I was like 21 inches above and they were getting dry and burnt. Doing better now. Only 6 weeks old GDP

Hey guys and gals, first time poster here. So this is my second grow. I have 6 honey banana s1 seeds that I popped and put into 1 gallon pots right at the beginning of July. They all looked happy for the first couple of weeks and then I started getting some weird leaf twisting and curling. I was told that it was probably humidity related and not to worry too much. Anywho, the plants are still growing fairly quickly, they just look a little sad and droopy to me. One plant has some brown spots on the serrated edges of a few leaves.

Here's some basic grow info. Currently in 1 gallon fabric pots filled with happy frog. They'll be getting transplanted into 5 gallon pots of organic roots (green fields). Im only keeping 2 plants in the tent. Tent is 2x4x7. The light is a sf2000 (200w) led that I have set to 90% and 24"....18/6. I have fed some silica, recharge, green aminos, and recently top dressed with natures pride. I check the ph with a pen and liquid solution. I've been told I overwatered, but I'm not sure I'm sold on that. I'm no expert, but I've been growing plants for awhile now and am pretty familiar with watering. Recently I've been giving em about 1 gallon of water split between the 6 pots, maybe every other day or so. Any input would be greatly appreciated! Thanks.

When you see twisted leaves it's almost always ph or overfeeding. When in doubt flush em.

Listen to the boys about your light. I am new to LEDs so I cannot advise with confidence, but I can tell you I made the same mistake, and my plants looked a bit like yours after.

Well I was worried about overwatering, so I gave em a few days to dry out. I prob went a day too far bc the soil became hydrophobic. Had to give em a little water at a time so they could absorb it instead of it running straight through the pot.

Being hydrophobic is okay, you just need to water slowly. My top soil is also hydrophobic for about 15 seconds when I water it because I do wet-to-dry cycles like the big boys here advised me to. Find out how much water you can pour into their pots at once WITHOUT the water spilling over the sides, but also getting close TO the sides. Lets say it is half a litre. Give each plant half a litre, then let it soak in for 15 minutes, rinse repeat until soil is saturated. 15 minutes gives the water on top time to make the soil below less hydrophobic.

I can only speak from my limited experience with soil: It is wet-to-dry cycle for me. My plants punished me every time I tried to follow Product advice about daily watering or every other day watering. All the experts here say the same thing, wet-to-dry cycles. A number of them corrected me in my own thread, telling me what I was doing was starving my roots of oxygen, so they drooped slightly.

As for the distilled water, I cannot give advice on that because I do not use it. My water only has chlorine in it no chloramine, so I can bubble it out in less than 24 hours.

Thanks brotha! One thing I learned last grow that I was surprised I didn't see mentioned very often, was that a ph pen will not accurately read plain ro or distilled water. Not enough ions in the water to get an accurate reading.....I think you need at least 150ppm or something like that. Someone correct me if I'm wrong, but if I stick my bluelabs ph pen in my plain distilled water, it will read 8.5 to 9, while my gh ph solution tells me it's actually 6 to 6.5.

Yea, that's what I've been told. Every time it's happened to me they have been in happy frog, I haven't fed yet, and I always double check ph. That's why the twisting leaves have been driving me nuts! I'm hoping maybe it's from too much light, since that seems to be the general consensus.

I just got a 3 pack of those Litmus paper strip things from Amazon so that when I do want to get serious about PH'ing, i'm ready. I don't have the patience to keep up with calibrating.

As for pH pens, I don't know how they work sorry haha. I do have one because I used to grow coco and pH was really important, but now I only test my tap water out of habit, I don't actually adjust my water pH for living soil ever. The products I use all have pH buffering properties, so I don't have to worry about pH. The pH of my tap water is about 7.5 and very low PPM, but no chloramine so its safe. I just have to bubble out the chlorine.

Is your tap water okay, or is it not great? I only ask because distilled water is pretty expensive haha.

Too much light will make the leaves curl to protect themselves. They look like you have some lockout.

Here's spider farmers recommendations for the sf2000 light. Again, I'm about 24" above the canopy and the light is at 90%.

Use the photone app to get a idea of how much par they are getting.

Water has to contain bicarbonates to be read with a pen. My well water is only 28ppm but pen reads it fine.

Leaf twisting like you have in the photo of the small plant is generally a calcium deficiency/lockout. I doubt it's a lockout if you haven't been feeding anything yet. Happy Frog is pretty mild soil, but does have some Ca in it from the dolomite lime.

I have found it's quite easy to over water in Heavy Frog.....er...Happy Frog I mean. Lol. It holds A LOT of water if you water to field capacity.

The plants look much better now though. They can sometimes outgrow an early calcium deficiency as they root out the medium better and the nutrients break down a bit.

I've found those to be inaccurate in the past. Maybe look into general hydroponics ph solution if you don't want to use a pen. Just a personal opinion!

I've been using a lux meter in combination with the ppfd meter app. I'll post readings tomorrow.

So you think that twisting could be from overwatering as well?

What about air exchange? Do you have air flow?

I have a 6 inch ac infinity exhaust in the top left of the tent. The bottom right vent is open and I have two, 6 inch oscillating fans. The exhaust fan is set to kick on if the heat gets to 80 or past 60% humidity. The humidifier is set to kick on if the vpd is higher than 1.2

I thought "foxtailing" was when the green leaves curl upwards from the sides. My bad. I didn't know that was what happened to buds. My reading comprension is getting worse with age, unfortunately. I was referring to the leaves doing that though.

I think your reffering to what's called "tacco ing" with the leaves lol.. Foxtailing happens with the buds, looks like weird long nipples growing off a boob..

Do you always run under 75 degrees? that will cause issues with growth speed and overall plant health. Also bump your light down to about 35 %, increase after stretch.
