any input appreciated

Any input is appreciated as this is my second time giving dwc a go ph stays in the 5.8-6.1 area. Temps are usually in the 70's it is under a 150 watt hps. It is bagseed as i want to understand it a little bit more b4 i sink a shitload of money into getting some good beans. I am using gh micro bloom 15ml of each. All input will be greatly appreciated.

Not the best of pictures but it appears you have yellowing, mainly at the top of the plant. You need to lower your pH down to 5.6-5.8 and NEVER let it out of that range. EVER!

the light just makes it look that way there is no yellowing anywhere on the plant. but thx for the input
