Dynamite DR80 400w MH/HPS

Hello I currently am flowering some Dynamite veg for 35 days from seed under a 400w MH now currently 23 days into flowering under a 400w HPS There are many small bud sites filled with white hairs, im just hoping it will fill out soon it is 22" high. Dynamite is a squat growing high yielder with good potency it is i believe a cross of White whidow and NL #3. It takes 45 days for flowering and an extra 10 for some nice pink and purple tones. I will keep updated with pics until it is done.

I havent used any nutrients sofar because all i have access to is a local hardware store. I gave them two Jobes plant food spikes two weeks ago 13-4-5 But that is all. Do you think that there are any BLOOM products or nutrients i can get that wont ruin my plant from the hardware store?

Day 23 of Flower
