My daughter sent this today. She said a couple of the plants were doing this?
Inquiring minds want to see. 
Thats the truth they looked perfect yesterday.

I’m deferring to others with more knowledge, bit I’ll throw my hat in as I’m open to correction.
I see what looks like mottling on my end. You said you fed additional fertilizer. Mottling to me equates to effusion (definition may change while I flip mentally through definitions). Think they may need some aerating and possible touch of calmag in some form?
As a side note and I’m not sure if you know, soil impaction is a sign of acidity, right? Acidity would cause aeration problems, right?

Yes they have been in those buckets 30 days now so i was thinking one fish emulsion feeding and go to flower in 10 more days once the plants have fully recovered from there last topping.

Sometimes stems get red / purple (shaded ones stay green) when they are protecting themselves from LIGHT. Same for leaves, they blotch…Some strains do this too. I also see some yellowing of the vein which points to nutrient - (nitrogen uptake)
normal -
- Incorrect pH – The pH being too high or too low at the roots is the most common reason to see a nutrient deficiency)
- Magnesium deficiency can cause purple stems. A good cannabis-friendly nutrient system has a significant amount of magnesium, but if you’re using very soft water, or RO water, you may need to add a Cal-Mag to your nutrient regimen.
- Temperature – Heat or especially cold can trigger red stems in some places. Big temperature fluctuations can also do it even if the temperature is in a good range.
- Humidity – Very high or low humidity can stress plants (especially young seedlings)
- Other types of stress such as light burn, transplant shock, or overwatering can trigger red stems
- Sometimes you’ll never know why and plants just grow out of it

Ok so i got a couple issues going on here. One it is just happening to a couple of the Blue Dreams. Then i remembered that i used a different potting mix on a couple of blue dreams. So i looked it up and sure enough the two i used Sunshine pro mix #4 on were the culprets. That is a low nute mix that i have been treating the same as Ocean Forest. So i did a cal mag foliar feed and added oyster shell powder and greensand to topfeed. Unfortunately my daughter watered them before sending the pics so i will have to wait at least untill tomorrow to give them a liquid tea feeding.

Actually the picture they sent me was of a pretty good plant. There was another that looked way worse with definite signs of cal deficiency. I will take a pick of it.

Can you please humor me? You scoped the leaves, right? I’m only asking because… Well because I can’t stop myself.

Checked for moving bodies?
I’m probably being paranoid, but I just did a battle with the start of mites.

@kmac03 could not find anything moving but there are several little grayish specks on all the plants.
most are 10% the size of this one. I had assumed it was dust off the top of my lights since i put in stronger fans sunday.

You know what boredom does? It makes me overthink a lot and occasionally I score. I’m feeling itchy about mites.
Is that knitting and thickening?
