Leaf issues

[Buddylove313]

Hey everyone, hope your day is going good. This is my first run so I’m still dialing everything in. I pruned these leaves off my girls but I can’t figure out exactly what the issues are. I have some assumptions but I like to double check. I can give all the information needed. Appreciate the help thank you.

strain: sunshine , platinum cookie
age: 6 weeks
Feed: started with 1 gal, plants seemed to take a while to dry out so dialed down to 1/2 gal per feed until they need more
Medium: coco perlite 70/30

I'm not an expert but that looks like it could be a calcium and magnesium deficiency, especially if you're growing in coco.

I’ll do some research on that, thanks man

Even most pros don't use just coco / perlite it's a disaster before you even started . Way too unforgiving . I would switch it to 12/12 right away and try a good soil/ pearlite / peat/ worm castings/ ect..ect.. blend next time

I'm using the same mix as him and I've been growing for less than a year and my plants are doing pretty well and its my first grow in coco.

I've been using epsom salt and home made calcium every few feedings and haven't had an issue. If the OP wants to take a look at the recipe search youtube for Bill Ward homemade calmag. I've been adding about half a tsp epsom salt and 1 ml calcium to 2 liters of water and giving it every 3rd feed.

I find this to be a great resource.

Yeah man it was recommended and I’m not too crazy about it it is unforgiving. I’ll try changing it up the next run thanks man.

May I suggest:
Feeding multiple times a day to substantial run off using a pH around 6.0.
Never use plain water and never let the coco get dry.
Good luck.
