Leaves turning brown and dying

**Vag420** · 16-01-21, 07:24 AM

They are autos in the 8-9week from germination and the leaves got brown spots and begin dying
I have been using the biobizz nutrient schedule and the last 2 weeks I have fed them calmag because there were some deficiency
What could it be?

So are these the same plants from November 24. Where you gave them calmag then too?
What exactly are you adding to the water. Like how much grow and bloom nutes? And how often do you water the plants.

Not sure if its my eyes or not. But looking at plant over all. Looks a tad hungry. And buds look under developed for an auto at 9 weeks stage.

Looks similar to my repeat issue, at a guess have you got hard water (check with your water supplier)? The addition of calmag would have massively overdosed it if your water is hard, cuz of the cal, not the mag. See if he checks back in before I carry on wafflin

I apply 4ml/lt of bio bloom and 4ml/lt of top max in the last feeding
In November I applied cal mag only once and now I started because my other plants had calcium deficiency (same strain ,same age )
I water them everyday 500ml per plant and they drink it
I use bottled water
Also they are growing slow 3 of the plants are growing a lot slower than the other 3 and I don't know why

Is your water hard or soft?

Hi Vag420, your using way too much bloom and top max and with bio biz you need to be using about 1ml per litre ofgrow to put some Ng into the feed.
What size and type of pots are you using?

**Vag420** · 17-01-21, 03:15 AM

Hard and I use 11 lt pots

Probably overdone it with the calcium mate, that's been my issue in the past. Try flushing the effected plants with about 3x the pot size with plain water and don't bother with calmag again. Already enough cal in the water. The leaves won't get better but it should halt it, best of luck mate

Looks like she eating her self to me sucking up the nitrogen but you seem to be adding plenty of feed. No not much about soil maybe try one them slurry tests. It's easier to spot ya own issues when you know everything you have done lol good luck bud
