what watts bro?
Im using Luminus cobs, and i have 300 watts available. I rearly use all 300, maybe peak them for a hour or so a day, but usually im around 200-225 watts.
I dont use dtw or ebb and flow, i use cocoloco, more soil media side. So, i cant really give a ton of info your your situation, but rule of thumb is watts=PPMs.
You wouldnt give a 3week veg, the same nutes as a 3 week flower, but you also wouldnt give a 3 week veg, the same amount of light of a 3 week flower, make sense?
If you know your total PAR at the very top your canopy can get best penetration over your area, You must let the veg plant grow with the light.
If you know that your max limit is 900 PAR, that is the amount you need for the last 3 weeks of flower, and at the beginning of flower set, your PAR should be no more then 450 PAR at that point of the grow. When you flip to flower, You should have HALF available PAR Left to use till finish. So, if you have a 10 week flower, you should be increasing light PAR, 450 worth, divided by 7, and i say seven, because last 3 weeks of flower is maxed at 1000.
So, from flower beginning, you should be adding about 65 PAR per week, till maxed at week 7 to finish. At week 3 of flower, FOR YOU, Your PAR shouldnt be more then 675 this week.
AND, you max PPM, shouldnt be more then 900 EVER, and this week, your flower PPM should be 650-675 PPM this week, or 1.3EC
Same with Nutes, slowly increase PPMs per week.
