Help im lost

Ok so ive thought and tried everything. Ph is fine. They were watered through because i thought the dose of vitalink plant start might of been too strong for a plant of its age. Plants still continued to show signs of burn. Then i thought maybe they are just really hungry so i fed 20% strength of canna coco a+b and some calmag. They still seem to be throwing some burns. Any help guys.

If there burning from feeding, flush and give them water next feeding measure start low and move up.

Ease up on the nutes a little more. What strain are you growing? Some strains cant handle nutes as well as others.

Ive currently watered one feeding of only 20% of recommended dose. Green crack.

What nutes are you using ? How much are you flushing ? How many just water feeds did you do ? Sometimes it gets worse before it gets better especially if you didn’t get everything flushed out.

Is that coco youre growing in? If so did you flush it before planting? What brand of coco is it?

Canna coco a+b .Sorry my mistake there was no flush involved just plain watering for 2/3 waterings.

I agree with swisha then. Look at the new growth if it still has signs of burn ease up on the nutes even more than 20%. New growth will always tell you whats up, old growth wont ever recover their burnt tips (usually). Be patient, tou should have researched your strain a bit more before overfeeding.

I know to check new growth tips. I grew this strain before with no problems.

Its seems you have a weak plant then id cull it and look (grow) for a healthier plant.

These are pictures of 5 feminised green crack.other people are growing it also.

Yeah and im sure alot of different breeders have sub par genetics of green crack than others.

Flush it properly and start again with a low feed of canna a and b.
Good luck with em!

that looks like straight coco you're growing in, i'd recommend adding at least 20% perlite to it for drainage and aeration.
i've bought cheap coco before and had problems with salt in it, had to really wash the hell out of it to make it usable.

Have always used perlite with my coco but i tried to skimp on it this time round lol . I ph'd and ppm'd it and they were at optimal levels

I grow in 100% coco. Let that coco dry out a little. It's too wet for those small plants. Let it dry out some and then feed with 1/4 strength nutes until about 20% runoff. Once the plants are bigger you can allow the coco to stay wet.

Sorry fell asleep but you have some good advice, let us know what happens. I had some emerald triangle green crack it was fire loved it good luck.

Thanks for all the help guys. I flushed them all today with a big flush. Hopefully now they bounce back

Do you have a journal ?
