6 weeks into flower, using canna biocanna each watering... I did have them about 5 in away from the cool tube for a few days, but the yellowing of the veins has me a bit concerned.

any and all comments welcome, even the non-constructive ones :fire:

You will get yellowing at 5 weeks in if it is a 8 week strain just flush it with water set at 5.5 and then re water when she drys off.

Yea like stated above you might need to leach your soil because of salt build up. There is a bunch of ways to do this, some more effective than others. But the main idea is to isolate the excess salts and rinse them away allowing the plant to start absorbing nutrients again.
