Not sure what the problem is.

1st indoor grow. Strain is Sour Diesel, week 3 of veg stage, in Schultz Moisture Plus potting soil mixed with Shultz Perilite, Hi-Yield Calcium Nitrate, and Epsoma Garden Tone. PH is 7.0. Feeding Shultz All Purpose 20-20-20 @ 1/4 strength through folar feeding twice a day, and by root once every other week at full strength. There is a light yellow almost white in the new growth, but as the leaves develope, they slowly start to clor in the yellowing. I am also growing a Kandy Kush, and 3 Holy Grail Kush plants and have none of these issues with same soil/fert schedule.

That soil has fertilizer in it and that fertilizer is a little strong even at 1/4 strength, its likely that too much has caused a nutrient lockout. Flush and give no more nutes until they're dry again, then go with 1/8th strength maybe. I've done this a hundred times, I never seem to learn =)

Agreed. Foilar twice a day is a lot as well. Most foilar applications call for once a week. And then by root too? Just way too much feeding.

Back off. Too much at once. Quit foar feeding. They still may burn with what you put in it. The garden tone was enough by itself. I use it.

Thank you guys! I appreciate the input snd advice. I guess I have always been under the assumption that foliar feeding was a safe bet unless you mixed your spray to strong. As in the leaves would only take what they needed type of thing. I gave them all their 2nd watering this week, and they have had no nutesfor about 4 days now. I guess I will sit back and see how they do.

Ok, so I backed off nutes, plants are looking much better now. Thank you all. Now I am presented with a new problem and need some advice. I have now realized that my Sour Diesel and pretty sure my Kandy Kush are autos. Sour Diesel started to stretch like crazy and is starting to bud, and the Kandy Kush looks to be in the beginning also. Now, I am switching out 4 of the 6500k tubes for 4 2700k tubes until they finish, but since I already went overboard once, I am seeking advice on how to approach with bloom nutes. I have Shultz Bloom Plus 10-54-10 with micronutrients. Box says to mix 1/4 tsp per gal, and to feed that with every watering. How should I approach? I was going to water the 2 tomorrow and give them their 1st dose of bloom nutes. Also, what else could I be adding like molasses and at what rates? Thank you so much in advance.
