Damage on the leafs
Bikoostarted grow question 6y ago
Alright another week another question for me to learn from. As you can see in week 2, there is some small damage on the first set of leafs. Please check the two pics of week two. What do you guys and gals think where the damage came from and what to do with it?
Cheers!

I have no personal experience with hydro, but It says in your diary that you are using over 30ml/gal for your Hydro A & B nutrients. Other diaries using the same nutrients have been using only 6 ml/gal during the first weeks of growing. I'd lower the nutrient supply to 1/5 of what you are giving them now.

Spotting issue consistent in all my grows. Have always thought Cal deficient but more Cal never fixes the issue. PH always checked with 2 PH pens 6.2-6.8.Always pops up around the same time in flower.. week 4/5. Brown irregular spots and occasional curling down on the fan leaves. The only things I have consistently used in all the grows is the LED light, RO water, and CALiMAGic. Switched to dry organics but now its back. N toxic?3y ago

Could someone help me to identify the issue my plant has?This girl isn't looking healthy anymore and I need to figure out why. What I did: I topped her pretty early but she recovered well (you can see it in my grow diary). A week later I transplanted her from 0.5L pot to her final autopot 14L. After that she had a hard time recovering.Leaves. Color - Yellow

Potential bud rot?My critical cure has some of the smaller leaves near and in the buds which are starting to turn rusty brown. Is this a starting sign of bud rot? Should I cut them early?
I do not see anything abnormal under the microscope or when separating the large buds by hand. Thanks!3y ago

Brown spots on older fan leavesSpotted some brown spots on 2 of the older fan leaves today. Any thoughts on what the issue may be?
Does not rub off- was worried about rust at first.
Some more info that could be helpful is that I am using RO water. Thinking about rasing the lights a little higher up too.Week 3

Browning leaves sections of leaf surface discolouredDay 18 leaf worries, browning areas, slightly metallic shine. I think from reading it might possibly be a phosphorus deficiency but I’m not certain so though I’d ask for advice.
Thank you for your time and all answers are appreciated. Have a great day!Week 2
