I need help identifying the deficiency on the lower leaves, looks like a combination of cal and mag ? Your opinions will be greatly appreciated. I was thinking of adding some calmag from the local grow store.
That’s not cal/mag at all it’s phosphorus/potassium burn plants of that size shouldn’t be getting any nutes yet. The burn isn’t severe but it is definitely not a cal/mag issue
Imo it's a cal/mag for sure. If you don't have any on hand, you can use some Epsom salt or even a small amount of molasses (1/2 tsp./gal.).. Calimagic is what I use, and I haven't had an issue since using it.
@Gropassion, ok... now I can tell you’re overfeeding your plants.
Do you see the dark and black rust on your leaves ? It’s Mag excess , and when they’re is too much Mag the plant can’t absorb Cal , creating those brown rusty spots.
First , check the EC of your media , might be way too high. You should feed them every 3 watering, following a Feed Water Water Water Feed W W W F ... schedule
Hi Guys, what can I say growing weed was all I ever wanted to do. I have 7 years of outdoor and 3 years of indoor behind me. I use 1.5m x 1.5m stealth tents with carbon filters, silent fans and a 16 x 6l Autopots, 3cm layer of leca pebbles on the bottom and a 60/40 mix Supaflora peat moss and pearlite. My objective is a even canopy of about 40cm with the lower half of the plant stripped or lolli popped. I have recently started stripping the leaves 2 weeks into flower with amazing results. At present I only grow Budha cheese.
