Hi guys I have 2 plants growing currently, same everything from strain to nutes. One has weird leaves, curling down, brittle and weird color patches. Currently running fox farm trio and I'm 3 weeks into flower. Was told to add cal mag to my mix last feeding because I'm in coco. Any help would b great, thanks

Alright thanks and yes I have been using fox feed chart. I feed twice a week and water between feeds with just ph water. So I'm wondering if the cal mag plus and fox farm together have to much nitrogen

If you are growing in soil then there is no need to be feeding twice a week. Feed once a week, at half dose, and raise the dose if the plants look hungry. Unless you really know how to read plants you need to go really easy with nutrients. It’s so much easier to see when a plant needs more food, and just add more, rather than run into situations like this, and cause major irreversible damage to the plant. None of those leaves will recover from that.

totally agree better to under feed than over feed as can damage root mass plant growth ,and bud growth and your final yield

This reminds me of a previous grow. Ended up being my medium was hot (too much nutes) and ph too low... which would also lock out calcium.

Check ph runoff and lower nutes would be my suggestion.

This is a coco grow... he should be fertigating at least once a day till he gets run off.

Some containers do not drain well and can make your roots sad, which will make your leaves unhappy. If it is a hard container you can pull up the plant and view the roots. They should all be white and vigorous.
