If you live in the US why would you order internationally? Years ago I had to order from overseas to get American produced seeds, but now I just buy from US based vendors.
I use them with canna products and have zero problems.
The main reason I started using autopots is because I have to be out of town for weeks and must rely on my wife to care for my girls. She can mix nutrients and ph properly but she just can't rap her head around when to water.
Lots O luck
As little as they are I would dig em up and put them in some sort of bagged soil. You would be better off growing in miracle grow than plain outside dirt and 99.999% of the time I would never recommend MG.
I remember 40+ years ago visiting family in Oregon we were riding in the forest and I made the comment, must be nice to have all this fallen wood no need to buy firewood. My cousin laughed and informed me they couldn't take it due to state rules. He said if you want firewood you had to get...
FFOF can be a little hot for some seedlings but they will be fine. Just remember there's enough food in FFOF to last several weeks. Wait until she tells you to feed her.
Patients grasshopper. My flowering cycle usually consists of tie limbs down during stretch and once they start packing I have to tie them up to support the weight.
Are you using straight coca? Like Flex says, you need to water much more frequently with runoff low ppm nutrients ph 5.8 -6.0. Dry coco equals PH problems.
I use Canna products start to finish. I rarely go over 1000ppm and that's in flowering. I never have any problems, no yellowing no burnt leafs nuttn but healthy plants that reward me with the best my girls have to offer.
I am very anal about ph.
What medium are you growing in?
Going by that feed chart you have nuked your plants. You can't force feed them, better to start half strength and add more if/when the plants need it.
I recently pulled 24 oz's off 2 plants 600hps and never once did I feed over 1000ppm.
I don't think flushing will help get rid of Malathion, but what would I know I'm an idiot for not flushing my cannabis.
My question is why would any grower have malathion to begin with? Unless they have a massive bug problem.
I'm sure glad I decided 20+ years ago to grow my own. no telling...
