Not sure what it is, considered powdery mildew but looking at the locations of some of it I'm fading towards sap.

White specs might be bug damage, possibly spider mites.

Looks like one of the issues is a magnesium deficiency on the yellow one. An Epsom salt foliar would quickly determine if it is a mg issue. If it's mg the color would improve within a few days after a foliar.

Light Schedule: 20/4 Light Intensity 25% - sprout to seedling 40% - seedling to veg 50% - veg to preflower 75% - preflower to mid-flower 85% - mid-flower (now) I don't grow autos but if they are the same as photoperiod with their demands then the light intensity should not be raised in late...

It's difficult to have a serious conversation on this topic because of all the parrots posting. In real life every time there is a competition in the winter there are a % of LED growers always complaining about small plants and blaming the temps. Never hear the hps growers complain about temps...

I'm not a coco grower so I'll let the others help going forward. You should start by comparing the ppm's of the water going in and the ppm's of the runoff and posting the results to see if there is a salt buildup in the medium.

I thought of another way to check the quality of the smoke before even drying. If you are trimming and collecting scissor hash, that hash put in a bong should get you wasted if the smoke is good.

It's great that you guys are doing your homework and learning but the drying process need not be complicated. Many experienced growers can tell you that if the smoke is dank, you can harvest a bud and throw it on a piece of paper and let it sit for 10 days in a room with very low humidity and...

I'm in soil, 3 gal plastic pots and different growers are going to find a variety of ways to succeed. I'm in mid flower, the stretch just ended and I have been watering 22 oz or less every day since flowering started. I top dressed with 3 TBL of ff ocean forest 10-7-7 in early flower and will...

Three of the tomatoes are fairly new cherry tomato plants. The other one second from the left is a 4th of July, a heat tolerant strain that has been going for 1 1/2 years. Small fruit but incredible flavor. It stopped producing for a while about 3 months ago. The problem was a buildup that had...

My hidden garden. Happy Growing!

5.8 is on the low side for soil if the results are good. Always a good idea to do a few tests. If you trust the results, then you would probably want to increase the PH. 2040 ppms sounds high for a slurry test. I'm guessing runoff is a lot higher. I was just looking but can't find info on a...

Don't use the dolomite yet. Do a bunch of slurry tests and let us know the results. FYI, it helps to have experience doing slurry tests. Make sure if you use a glass that there is no soap residue on the glass. Any soap will distort the test. You can always have a sample of your soil tested for...

Dolomite is best if mixed in a soil when amending but in situations where a grow is in progress and soil ph needs to be raised it can be used as a top dressing. Buy a gallon of distilled water at a pharmacy to do the slurry tests. Why would I be testing runoff in an organic grow? Isn't that...

I only skimmed the thread. A couple of things that stand out unless you are doing it or it was mentioned. Each time a soil is amended a small amount of dolomite lime, or some other PH buffer should be added. A grower reamending soil many times should understand how to test soil PH. Each grow...

It's just a genetic expression. It usually only reveals itself when a plant well grown IMO. It is usually a sativa dominant strain that does this.

Looks like caterpillar damage.

How deep is that pot you are using? I am curious what your soil looks like below the surface. I'd like you to take a pic of the top of the soil again without disturbing it, then take something like a fork as I used and scratch a half inch of soil like I did in the pics below. I'd like to see if...

It would help to know if there were any feedings after the 1st feeding when flowering started. If these were fed at the beginning of flowering, I see a couple of possible issues. 1st you have water heavy with calcium which is what is creating the crust on your faucets. The 1st pic ingredients...

I have tap water similar to yours. Can you list everything including the NPK for each top dressing or bottle feeding you gave the plants up until the yellowing began. If you can be detailed with amounts given and dates or stage of growth when feedings are given. I have a feeling it's related to...
