Dry spots on sugar leaves, plant late in flowering, also spotted on another one in the same reservoir
Cremostarted grow question 3 years ago
Hi guys,
my plant is around 2-3 week before harvest.
What is the cause of the these dry spots on some of the smallest sugar leaves on my plant?
The ppm might be too much and is around 1200-1300ppm.
PH is 6.0-6.1
I've spotted it on one other plant in the same reservoir.
Thank you

Looks like phosphorus deficiency. You are also feeding too much nitrogen. In flowering a npk ratio of 1-2-3 is best till you get the hang of nutrition amounts. Change the water with a high diet in potassium and phosphorus and minimum nitrogen since you ate pretty rich on it. Ph about 6.2 to 6.3 range is better as well. Good luck and should stop those signs once done. 🌱

Hello it really looks like you have light burns on some leaves. This dry spot with this color is characteristic. It can be due to your lamp which is too close of your plants or some water drops which act like a magnifier and burn the leaves. Don't worry for that. Just adjust your lamp if it is too close. good luck. Bye

Thank you @Roberts you're answers are usually on point! I'll def try it. Yesterday I removed around 15L from the 70L reservoir (around 40l are left) and added 20 liters of ph adjusted water to bring it down to ph 5.8 because I thought I overhead 'em a bit. I'll do what you say and will keep an eye on them :)

Buon giorno weed doctors, did anyone have similar uniform chlorosis at the top or maybe knows what's up? What could be the reason and the solution? ThIs this some sort of immobile nutrient deficiency or excess? Could this be caused by heat and light stress? She is 80cm tall and almost touches the lights in the tent. I'm usually suffering from Calmag and Nitrogen issues and haven't yet experienced yellowing from the top. Thanks

What is this Jawn on my Leaf Device?What is this on the leaves? Brand new clone 1 hour in my ownership. I sprayed her with Bonide Captain Jacks Copper Fungicide in case it is PM. Doesn't look like PM though. Looks almost like hard water deposits. What do you guys think?

Should I do full flush til runoff is 300ppm?So, it is obviously a deficiency, which probably caused by a lockout. Will the full flush solve it?
Yesterday I fed her a full dose of flowering nutes. Including K. It didn't change much. Lower fan leaves continue to go yellow.
Today 3L water, pH:6.2,
runoff:0.6l, ppm:1450, Ph6.0

Identify Issue: Brown Spots, Lower leaves first, from outer-tipsShowing up on 2 out of the 5 in my soil bed. Front 2. Transplanted 10 days ago, went well enough.
Watering with tap water, never tested but didn't have an issue last run. Same soil, but I did add 8 cu ft of new soil to the top. Gently amended with b6, Kashiblend, coconut powder.

White spots on a few leavesAny idea what these whitish yellow spots are? They appeared overnight. I'm growing in ffof with perlite and ewc. No nutes added yet, just bush doctor cal mag at half dose 3 days ago with great white, recharge, and photosynthesis Plus which was the last watering of 1.2 liters.

Advise to flush or feed in VegDoes this is look like a nute burn, deficiency, or ph problem? The two plants that are growing a tad taller have had yellowing tips some curling downward. Don’t want to overreact and cause it to worsen, they’re looking healthy otherwise. Any advise whether to flush or feed?

2 autos with crispy feeling sad looking leaves, how can I help them? (more info in diary pl & crit)2 of my autos have been growing leaves that feel crispy and look deformed. I have been watering when the top 5 cm of the soil dries, but I fear maybe I fed them too much nutrients. The temp has also been on the high side (30C 80F). What could be wrong and what can I do for them?

Thoughts on leaf symptoms? The other plant in tent is doing same thing,but plant in other tent getting similar feed not. see diaries for more picturesK deficiency? Hard to believe that can happen in 65-gallon pots.Are getting big though.New growth tips looked yellow,hit them with water-soluble K and the new growth edges seemed get green.Some toco-ing, humidity is kinda high. Too intense light(800 ppfd), not enough C02 maybe?

Spotted LeavesMy ladies looked good until recently, it has been very warm the last few days. Then they began to let their leaves hang down (didn't get enough water) and gradually turned yellow, now they are getting spots. This is my first grow and I am not sure what it could be.

Yellow on leavesDay 13 leaves started to look yellow / dull on tips hasn't seemed to improve 2 days later, it is the auto soil premix I'm guessing the roots are getting close the soil and nutes kicking in or does this look like another issue?

Leaf IssuesHey all, my almost 5 week old Moby dick auto flower is starting to show some issues in the first week of flower. She got a dose of Veggie nutes 5 days ago, and a little bit of Bloom yesterday trying to fix it. Temps have been high and humidity low, would that cause this?

New growth looking strange and growth slowed down (wilting?)The new growth of my plants are looking a bit strange, and growth seems to be slowed down.
Could this be that the light is too strong? Or can this happen if the humidity is too low?
I already installed an humidifier but looks like its not helping.
Whats going on?
Info in week 10.
