Chimkenstarted grow question 5y ago

My current feeding water consists of: 1. 20 l of water 2. 40 ml of Canna Coco A 3. 40 ml of Canna Coco B Leaves definitely show something is wrong. What would you recommend to fix this?

Add some calmag to your feeding and you'd be good. From my experience seeing rust spots show up usually is a mag deficiency. Hope this helps your plants over all they look good. Happy Growing

Add 1ml/L calmag with your canna nutrients or just use 2ml/L floraNova bloom instead it has it all in one bottle

First place to look is ph issues. Consider flushing with ph’d 1/2 strength nute water. Do you have just coco? If so next time maybe add 25% perlite as a lack of oxygen can cause nutrient uptake issues.

What could be causing this?I'm experiencing yellowing, browning and crisping on some leaves, but only on the main colas so far. I have checked the PH in and out. In has always been perfect, but the PH of the run-off was 5.8 so I'm flushing to rule out nute lockout. Anything else it could be??

Magnesium Deficiency?Is this plant suffering from Magnesium deficiency? I noticed some of the growth is yellowing and the leaves are curling upwards at the tips. The tips of the leaves is where most of the discoloration is as well.

Nitrogen deficiency or could it be nothing In the pictures you see some yellowing and small spots. I don't know if it's Nitrogen deficiency or not because it stays with those two leafs.

Beginning of week 8. Deficiency? Nute lockout? Normal for this stage of its life?Beginning of week 8 and her leaves are showing more spots and discoloration everyday. Is this normal for an Auto in the late stages of flower? Or do I need to feed more? Maybe a flush? This strain says she takes about 10 weeks start 2 finish.

Newer leaves also turning yellow at the tips. Flush?Newer leaves also turning yellow at the tips. Started to give the plant Terra Bloom,Sugar Royal, Pure Zym and power roots again after only giving it water for 2 weeks long. Is this a nutrient burn and will a big flush help it out? Doesn't a big flush overwater the plant?

Nitrogen deficit?The bigger plant is struggeling a bit again. After some talks and readings it could be a nitrogen deficit but am not really sure how if I should react to it, since the need of the plant should get less for nitrogen in the next weeks. Please read my journal for more information.

Yellow Leaves Yellow leaves started at the bottom and are making their way up. Also noticing bud leaves are turning a lighter more lime green. Yellow leaves end up shriveling up and falling off some have brown splotches. Approaching Day 70 and don't know what I need to do to fix this.

Starting to yellow So I had good growth up until 2 days ago when the one plant started to yellow. I had them going 24 hours a day and I got grow dots mixed in the bottom two thirds of the pots. Could this be light stress? or could it be hungry?

Did I give too much fertilizer??So I decided to add in some soluble fertilizers. I gave it a 1/4 tsp (50% of recommended dosage) a couple days ago and noticed some yellowing of new growth on the bud sites. Is this a sign of excess potassium and phosphorus? I gave it Fox Farm Open Sesame (5-45-19).
