Your nutrients and water:
10) Source of water? filtered tap water What's it's ph before adjusting? 6.8
11) Method of checking water ph. (ph dropper test kit)

14) How often are you watering between feedings, and how much per watering?watering every 3 days. i quit feeding them when i noticed the leaves curling. i thought i had burned them.
15) Any additives or tea's? i added a .5 teaspoon of sugar to my food a week ago
16) Are your ph levels stable, or do they fluctuate? just ran my first run off test. the 2 plants that are growing ok have fine ph sitting about 6.8. the small guy is about 6.0
17) What is your ingoing water's ph? ...your runoff ph? ingoing is 7.0 maybe 7.2
18) Do you foliar feed? If so, with what, how often, and at what time do you spray? just sprayed using maxicrop seaweed diluted way down.

22) Have you seen signs of insects in the growroom? no

Your strain:
23) What strain are you growing? cannalope haze seems fine. ak 48 seems ok except leaves are clawlike on top growth. and G force. is the weak link. had some nute burn i think. leaves are twisting some and a few brown spots.very stunted growth.
24) From seeds or clones? from seeds
25) Is this an autoflower strain?nope

How long have they been in the same pot? Before their next feeding, when the rootball is kinda dry...carefully slip it out of the pot and see if they are rootbound. If so...they need a transplant into a larger container.

If leaves are showing stress, it's usually a good idea not to force-feed 'em. (spraying)

Are you using a color-coded test kit? if so, I doubt your runoff ph is that high. The tinting of the runoff skews the color-coded results. Likely it's a tad lower. Keep your ingoing numbers near 6.8 or 6.9, and you should be ok.

Sugar won't give you the results like unsulfered molasses will. Sugar as a stand-alone additive is unacceptable, unnecessary and potentially harmful to the ladies. Also it attracts bugs and insects.

I'm a firm believer that cannabis grows better, stronger and healthier with a dark period. I've tried both and always am underimpressed with the plants that recieve no dark periods. There's a thread around here somewhere that shows how to increase females through light manipulation during growth phase. Were I you, I'd find that thread and have a look.

Would be nice to have a picture, but might be overwatering too. Yellowing with 'sores' on the leaves is usually either overwatering (in the growth phase) or they need calcium. (in flower phase)

When you OD on your base nutrients the leaf margins crispify, and leaves tend to yellow as the nutrients get locked-out. (more extreme cases) A good flush and a nutrient adjustment (less often or less nutrients) clears that up.

The claw is uaually either ph swings, rootbound, overwarering...or a combination of the three.

they have been in the same pot for a month. the gforce is the one I am worried about.the cannalope looks great. and AK48 has the fan leaf tip curling up and ramshorning but also the leaf edges are curling upward.(mag deficiency?) i have been just watering. no food since the leaves started curling. i am using a drip color ph tester. when i tested the plants, the cannalope and AK, runoff was at about 6.8. the runoff was pretty clear. the runoff in the Gforce was about .5 lower looking than the other 2 plants with more muddy runoff. i think i over nitrated them. if i need to move them into different pots should i transplant or cut the bottom out of these pot and doublepot? I have been reading alot and it looks like I might have a mag. deficiency.if so what do i do to correct it? i have included pics. thank you so much for the help.my pics wont fit can i email them to you?

I'm pretty sure your runoff numbers are off if using the ph test drops. They have a color-coded chart, right? Tinting of the runoff water (and likely the nutrients themselves) skews test results.

If that's the largest pot you've got you might be able to get away with slipping-out the semi-dry rootball and adding potting soil to the bottom of the pot, and the sides once it's back in the pot. But you have to be sure to allow enough room at the top for watering. If still in veg you might be able to slice the roots and re-pot, but I wouldn't advise it unless you have a back-up plan. Tiz an advanced technique. Sort of.
Once in flower, you shouldn't dick with the roots too much.

What makes you think you have a magnesium def. and have you read the thread about epsom salts not being a miracle cure...?

is a 3 litre pot too small for indica? I have heard i can cut away the bottoms of the pots and put a larger pot if needed. They are 3 weeks old if i am going to put them in different pots i guess i should do it soon huh? i have some pics if I can email em to you. they arent looking too bad right now except for the claw. i did a mild flush on the stubby one that has seemed to help it. i dont know how long to wait to feed it.I will try to make the pictures file fit on here. thanks a lot

Isn't the bat guano an ammendment, rather than a stand-alone fertilizer? You'd be better served were you to go get quality nutrients that are cannabis friendly and provide for the needs of the plant. There are a few very good 2 or 3 part nutrient 'systems' that will take your plants from seedling to harvest. Most quality nutes you hear about here at CanCom also have a feeding schedule online that's easy to follow.

Is it a granular guano? Which one? Some are very high in phosporous, which will dick with your ph. Plus, granular fertilizers are not optimal for cannabis unless perhaps you are growing in the ground outdoors. Once the granular (time-release) nutrients are in the pot, you can't remove them. With liquid nutrients, if you OD the ladies, at least you can flush the nutrients out of the pot.

it is sunleaves granular that i mix with water its analysis is 10-10-2 I thought that would work well. should i get a different grow fert you think? maybe that has been my problem. lack of other nutes from just using guano? i think my ramshorns have started to go away. new growth looks better. after a flush once I return to normal feeding should my ph go back to normal given that all of my nutes are set up properly? i got the pics up finally. i am curious what is causing the leaf edge to curl upwards as you can see bottom left pic and top right pic. the pic bottom right is the g force. notice the leaf twisting?

here is a few more pics. thanks for all the help.
