Brown/white spot
Kratistosstarted grow question 3 months ago
Hi everyone. The plant is a photo on her 7th week of veg. I give solid ferti and diluted compost tea water then appeared white spot on old leaves and the new leaves have tips burnt.
Is it PH problem or PH mix with overfed?

Did you splash feed on your leaves?
Water drops can act like a magnifying glass and concentrate the light onto the leaf in a tiny spot and burn your leaf.
Otherwise if you have any feed in the water and get some on the leaves, the water evaporates and leaves the feed behind and it gets very concentrated and that can also burn your leaves.
This doesn't look like nutrient burn from the plant getting too much food to me.

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?

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.

Heatlight stress?Can someone tell, are these brownish tips the sign of the heat stress or something else? And how bad is that for the plant's not so distant future?
She grows indoors. Peak DLI was almost 60 but very briefly about one night. Now it's dimmed to 40dli/~600ppfd/ 20/4 schedule.

Tiny holes!?This morning while looking I noticed tiny little holes on some of the leaves on one of my plants. I didn't see any pests with my eye, and I tried to use my phone the best I could but couldn't see any. I've also heard this could be environmental/viral. Any thoughts or ideas?

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?

Spots on 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.

Is it safe to tweak your light cycle times when you flip?I'm getting ready to flip and was hoping to adjust the cycle time when I do. My light is currently on from midnight to 6pm, but would like to switch to 9am-9pm or 11am-11pm to better align with my schedule. Am I safe to adjust or should I keep it at 12am-12pm when I flip? Thanks!Other. General questions

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.

Burned tips and white spotsHi, I have a auto plant in its 7th week. Today I noticed that it has burned tips. The white spots have been there for longer, I dont know if they are related to the same problem.
Im new to this and what I came up with is that the white spots could be a cal defincentcy?
TY guys
