First try 7-2-2021

Decided to top her this week. Just the very top node, and left about 1/4 inch of stem above top node after the cut. Also pulled out some small underleaves at 1st/2nd nodes. After topping she grew another 1 cm over following two days so looks like minimal shock now. Lots of growth starting on lower bud site limbs. Last week’s growth reduced light distance to under 16” so we raised the light to 25” but we are going to have a problem getting too close to the light if we don’t train her flat next week. Running out of time for training given the short autoflower time span, so we will HST next week. Nutrients concentration is going up spontaneously as water absorbed by plant and evaporation - given high air temps this week. PH has held steady at 5.9 for the week with just a small amount of pH down added with water change at start of the week. I feel like the fox farm recommended ppm for week 4 is just too high as the leaves darkened drastically last week, but no stunting in growth suggested I keep as is to see how she responds and she seems to like it but the neighboring lettuce is not happy at that concentration so we are going to hand water the lettuce going forward.
