Just checking they still look good should I start feeding nutrients they are on just water atm they sprouted 12th July

What ae you growing in? FFOF is good for 3-4 weeks, HF is good for a couple weeks, kinda depends on whether/how much your soil in amended. In any case, the leaf color looks good, when you start nutes, start at 25-50% of recommended, see how the plants rreact, then adjust accordingly.

look healthy mate may need potting up soon
