Pineapple Auto- (first ever grow)

Day 36- Not major defoliation, but not just picking off a couple leaves like I have been doing every other day. Thought I took a little more then I should, but it all grew back within a day or two. Day 37- slight nute burn or light burn appearing- thinking it is nute now that it has been a couple days and minorly spread Plant under vivosun is further along in flowering and appears to be a little pale. May run filtered tap water instead of RO to see if that helps with calcium def. or whatever may be causing some small browning spot on one of the leaves. Feeding: 1/4 bloom strength and 1/8 veg nutes every other watering (every 2 days now). on last feeding I did a half water half feed instead of just water for the Bestva light plant. Bestva light plant- 11" tall, Vivo-9.5" tall Still selective defoliation whenever needed.
