Day 53 flower - Sativa leaves are going light green - yellow green

Day 53 into the flowering cycle and half of the plants are starting to show signs of sickness. Possibly due to nutrient imbalance. Unfortunately this has been going on for sometime now. But we didn't realize it was not going to self-correct.

Apologies in advance. Phone pictures.


Most of the indica plants appear to be thriving. Leaves are green to dark green. But as you can see in the photos the sativa plants have light green and worse yellow green leaves.

The Sativa were transplanted somewhere around 20 - 30 days into the flowering period. They went from a 1 gallon smart pot to a 5 gallon smart pot.

Aside from that they have received the same low stress training, topping and feeding as the indica.



Damage Control:

We're trying to figure out what is needed to bring these beauties back to the healthy dark green color range.



History:

All plants are being fed on an alternating schedule. Nutrients then the next time is plain pH balanced water and then back to nutrients. Both nutrients and water feedings are pH balanced to around 5.5 - 6.5.

On nutrient feeding days the plants receive, MaxBloom and CalMag. We were trying to keep things simple and not use too many supplements.



The leaves below were pulled off one of the sativa plants shown above. We are not sure at this time if this is a nutrient, light, wind or even ectoparasite issue.



Name that sickness
Seriously we would love to know what the issue is and how to correct it.

What lights are you using?

Nitrogen deficiencies don't usually keep a green vein. By the time N def hits leaves higher up the plant the lowers are literally crispy and have fallen off or a ready to drop.

With light bun you get that green vein, the leaves don't drop off and you get it on the fans getting a lot of light.
Could be the sativa is just more sensitive.

Could this be a result of the late stage transplanting? The plants with the leave color issue were all transplanted during flowering.
