Blackberry Auto Indoor Veg Tent Sumer Fast Buds

It looks like it is the last week of veg for the blackberry auto. She's gotten pretty tall since last week and shooting some pistols. Noticed the new growth has some yellowing on the tips right as it comes in but goes away as the leaf grows in. I think this is from the soil drying out between waterings too much for this plant and ppms in soil got a little high as a result. She only got watered since this week. But it was a heavy watering I had runoff I had to dump. Going to aim for two waterings this week. And top dress with dry amendments.
