Watermelon Zkittles - Tremojem Farms

Looks like plants are doing well with the transition in lighting schedule, which included me reducing light by one half hour a night until I reach a 12 hour on/off lighting schedule. I defoliated one plant that exploded and might need to do the other of the two Watermelon Zkittles plants for the same reason. Watered with 4 gallons of water including Cal/Mag and Manganese. 1 gallon per plant. 5/4/2022 So yes, I had to trim some fan leaves off the other Watermelon Zkittles plant today. They are growing like weeds...lol. In: PH 6.47 PPM 1070 EC 2112 OUT: PH 6.69 PPM 1721 EC 3474 5/5/2022 Watered with 2 gallons including Cal/Mag and Manganese. Half gallon a plant. No nutes cuz according to the internet I am already hot. See the chart I added to pictures. Then look at my history...I am new, but it looks like I need to get the salt out of roots. Just learning is all...with mistakes lol. In PH 6.11 PPM 392 EC 774 Out No measurable runoff to take readings. Some, but not enough for accuracy. Please advise if you wish. 5/7/2022 Their really taking up water now. I watered with 4 gallons, 1 gallon for each plant. No nutes, only Cal/Mag and Manganese to supplement RO water. I am still in transition with the lighting schedule as I reduce by 1/2 hour a night. Plants look great. Just worried about runoff and salts in roots. This is when they need nutes the most, but my numbers were high, so I am trying to correct and get good numbers and then start feeding. If I am wrong then please let me know. All that being said, I don't see any problems with the plants, and they look tremendous, but I am a newbie so... In PH 6.1 PPM 399 EC 792 Out PH 6.7 PPM 987 EC 1974 According to my chart in the pictures, my numbers are good now. So, next watering will include nutes.
