.5 conversion in an 80 deg sealed room running CO2. Ebb and gro buckets with hydroton fed 4 times for 30 mins ea while lights on. I started at 500 in veg and the plants immediately yellowed under t5`s. bumped it up to 700 and they got their color back. Moved em to the flower room with Hps lights and they yellowed up again. Kept bumping up the nutes till they greened up. That's how I ended up at 1100. Theyre rocking and there isn't one burned tip or clawing. They look perfect.
Hi Dollar..... Yea under normal conditions if you see and yellowing all it takes is a bump up of the ec and that fixes it . Let the plants tell you how much the need and thell thrive.... VB is some really good stuff...... Hey if a rookie can do it... I wish my room was as full as yours......
