Her @agedmaster hope your having a good day my friend.Hi bluter here are better pics the leaves are not crispy today
Can you get a clear shot of those buds.

I hope the original poster stops by soon but he has not participated in any thread since Monday evening. I am curious about if anything happened with these plants and the spots in the leaves that were brought up in the first msg.Does the problem still remain?
In the two middle photos in msg #28, yes, out of focus and possible movement. But the first photo and the 4th photo do not have the blur or any major out of focus. And, that makes the white areas on the leaves look like they could have splotches of something, maybe Powdery Mildew. Then again, it could also be the angle of the growlights and the camera producing hot spots.i see more a camera blur than PM but i'd really hope he follows up with better pics
The plants still look healthy and the amounts of what might be Powdery Mildew as still low enough that something can be done to save the harvest.but still see questions in the others. i guess we're not throwing a lot of confidence ..
Hi john u are correct i was putting nutes in random. even the bloom feed after looking i noticed my bloom feed needs a first then b hopefully it corrects. ive been feeding right past 4 days i flush with water ph 5.8 and run off spikes again to 6.5 on 2 and 7 on other 2. should i have ph'd the hydroton . something is making it spike but i dont no what also i had to flush with 2 gallon per plantIt is probable that your issue can be corrected and the grow progress normally.
I would re calibrate your pH meter ASAP before proceeding.
1) re calibrate your pH meter weekly to maintain accurate measurements.
2) in the photographs you have posted you have 2 issues displaying at cause by the same nutrient lockout and pH imbalance. Calcium deficiency and phosphorous deficiency.
3) there is a best order of operations to add the nutrients in, adding the nutrients randomly or in improper order will create a nutrient lockout.
Plants grown under LED lights require additional calcium and magnesium.
when mixing nutrients and adjusting the nutrient mixtures pH you must allow waiting time to approximately 12 - 20 minutes to allow the pH to balance after initial adjustment. the buffering effect of calcium excetera will first display a reading then pH buffer rebound shall change resultant pH of the mixture.
While adding the nutrients if you use a calcium supplement the calcium supplement must be added first to the water.
if using a calcium supplement in hydroponics do not allow the pH to rise above 6.3 otherwise the calcium will precipitate to a solid in suspension and not be absorb able by the plant.
to restore the grow medium to a neutral state requires pH adjusted water be slowly poured through the medium leaching out the salt buildup and other harmful substances. Measure the runoff waters pH to determine if further flushing is still required.
If you have a 1-5 gallon sprayer to wash and flush your grow medium .
I would flush your rock wool and hydroton grow medium with at least twice the volume of pH adjusted water until your runoff pH is 5.8.
All hydroponic grow mediums require flushing with clean water to remove manufacturing chemicals such as mould release agents and machine lubricants from the grow medium before use.
Mix the nutrients well into your solution.
the order in which i adjust and add nutrients is
initial pH adjustment
Calcium supplement
Micro nutrients
Grow nutrients
Bloom nutrients
final pH adjustment
You want pH 5.8 for hydroponic and soiless (peat moss and coco coir) and pH 6.5 for soil.

you can remove the worst damaged fan leaves and open up the nodes and branches to the light.

I am not talking about Bud Rot. I have not heard of growers saying that Powdery Mildew on the leaves takes away the smell from the buds, either.Definitely not pm as ive had problem from week 1 of veg buds sticky as And smell like lime....(cut extra stuff)...... and leaves dont smell like rot either will post pics at end
hi smoking wings its my camera i cant get light in tent with light off so i use my phone camera light but i cant keep the light on so it only flashes when i take photoI am not talking about Bud Rot. I have not heard of growers saying that Powdery Mildew on the leaves takes away the smell from the buds, either.
I did mention that the white showing up on the fan leaves could be caused by the lights but until you can take some new photos of the same leaves we cannot say for sure if anything is going wrong.
Also, any possible Powdery Mildew problem is something different than the problems that you brought up in the first msg.
Don't do anything.hi again i cant get photos yet ive checked runoff ph its spiked to 8.5 should i try doubling bloom feed ive checked online it says there hungry
the buds look ok ive done about 15 grows this is first time hydroponic going back to coco after i think they need 2 feeds per day in flower to keep ph down from what ive been readingDon't do anything.
Wait till you have some current pics and we can see exactly what's going on.

Many years ago I was active in the aquarium hobby and was advised that if I should ever use the hydroton clay in an aquarium or pond that I should first flush and well wash the mould release agents and machinery oils from the hydroton otherwise these chemicals would severely harm and/or kill pond fish. The easy method is to place the hydroton inside a bucket with a flowing water hose and rinse the hydroton until any powder discoloration is flushed out. leave the hydroton sit in clean water for hours and repeat the flushing process for several times per day for days. Before use allow the hydroton to sit in pH adjusted water for several hours.Hi john u are correct i was putting nutes in random. even the bloom feed after looking i noticed my bloom feed needs a first then b hopefully it corrects. ive been feeding right past 4 days i flush with water ph 5.8 and run off spikes again to 6.5 on 2 and 7 on other 2. should i have ph'd the hydroton . something is making it spike but i dont know what also i had to flush with 2 gallon per plant

hi again i cant get photos yet. ive checked runoff ph its spiked to 8.5 should i try doubling bloom feed. ive checked online it says there hungry or do u think i need to feed more than once per day. ive been hand feeding just before i turn lights on my root temps are 15c lights off
