Top leaves coming out skinny

Growing some gorilla cookies by fastbuds in coco and shes had issues throughout the grow unlike the forbidden runtz next to her. Currently feeding 1L at 5.8-6 ph per day. Since shes started pre flowering the top leaves have been coming out skinny. I lowered the water intake incase it was overwatering but after 4 days still the same. Ive been giving half the recommended nutes using the canna range.
Any suggestions as to what it might be ive hit a blank.

You should be feeding in coco daily (minimum) until runoff and removing the runoff immediately. If it were me I'd feed a lower ec with just the a+b or 3part no additives. What's your temp? 78-85 is pretty ideal. 75 or lower and you're gona run into problems especially with LEDs. Looks like your having an issue with the plant being able to take up what it needs maybe due to cold temps or ec buildup in your coco/root issue. It's just a guess though. Hard to say without more detailed info

My temps are usually 78-82 and around 70 at night. Im gonna start watering into runoff with something to catch the run off. I dont measure ec but i guess ill start doing that and buy an ec pen. Also should my night temps stay above 75?

I keep mine fairly constant with just a few deg diff at night

I've seen that with a lot of strains when they go into flower. I have a GG#4 mother and the two plants I flowered from her did that too so may just be strain related. Otherwise yours look great.

I blew up the pic on my computer for a closer look and she may need some iron if you have anything with a bit of that. Just a tiny bit tho. I near killed the GG and a couple other plants flowering at the same time with excess iron and didn't think I was giving all that much. Flushed the hell out of them and got them back on track but lost a lot of leaves and yield.

Could be a general lack of micro-nutrients too. Either they're not there or unavailable due to pH or other issues.



Save this chart. It's a pretty good one to help figure out wtf is going on some times.



Good luck!

I like 75 for light on temp and have the heater thermostat set for 70 so it won't go lower than that. My grow room is in a cool basement so needs heat to stay at 70 even in the summer. I grow in ProMix with organics and use MH/HPS for light tho so YMMV.
