I need help diagnosing this (Pictures)

[Mr.Gabz]

Hello,

First time growing here in a little 4x8 tent.

I'm 1 month into flowering, growing in pro-mix with a 400 watt, temp and humidity is good, this is a nutrient issue I'm pretty sure.

I have been feeding General's organic Bio Thrive Bloom 2-4-4 once every 3 watering since 3 weeks, respecting dosage on the bottle.

I know I had a claw issue due to nitrogen toxicity in veg and I feel like there are too much nutes in there. I bought Cal-Mag and did 1 watering with it once because those leaves look like a calcium deficiency..

I'm kinda lost actually and I need people with experience to put me back in the right direction.

Here's another picture where you can see the tip of the leaves curved and dead.

looks like over fed to me!!

They look wet.Are you foliar feeding them?

Are you sure they had a nitrogen toxicity? Seems unlikely with the amount of fertilizer you were giving them.

Don't treat anything until you are confidant that you know what if anything is wrong. Often, people will be in such a rush to "fix" any hint of leaf discoloration or appearance.

How often are you watering them?

 

[Mr.Gabz]

I just foliar sprayed them when I took the pictures, it was in the morning when lights just turned off 2 minutes ago so don't worry, I'm not over watering them, I always dry the soil a bit before watering. I only had this issue once and never again.

I foliar spray them with cal-mag since 2 days once a day. Been feeding them cal-mag once and I'm now watering with water only.

 

[Mr.Gabz]

Oh and as for nitrogen toxicity it happened during veg and I'm now 1 month into flowering.

if you had N toxicity in veg, and you did not correct it, and now are in flowering one month then i would say you hav for sure run into some over feeding problems...foliar feeding will not fix the problem, only prolong the inevitable...

Please stop spraying your plants in flowering. Please.
They really don't need the extra moisture, specially in the buds.
And when you stop spraying you can take pictures that would be diagnosable.

my suggestion would be making sure to water at around ph 6-6.2 and stop feeding until you see some improvement

I think, run some ph water preferably ro at 6.0. Then, the next watering, run 2.5 ml of cal mag per gallon with light nutrients. I also think they are over fed. Flush out the medium, then run your nutes at a much lighter dosage. Bottles usually tell you to use double the required amount. If the tips of your leaves are even burned that means you are overfeeding. They should bounce back. And i agree no foliars on flowering plants if possible. Especially after like week 3. And if you do ,you should rinse them with clean water at a neutral ph to get rid of any leftover residuals.

The crispy look suggest mites to me. If you have Cyclamen mites you will need at least a 50x magnifier to see the eggs. They show up as teeny tiny little clear dots. Look very very carefully on both sides. If you have mites there are tons of articles on here on dealing with them. I fought what i thought was nutrient problems, water problems, etc etc. and in the end it was mites. The crispy leaf to me gives it away as mites.
