Possibly very early signs of nitrogen deficiency. What is the ph of your water/feed? Are you feeding them? If yes, with what? How much?

Doesn't look that bad though tbh. Have had far far worse still come through and produce very good weed. Worry not.

Thanks so much - haven't checked PH levels, 1st second week half strength nutrients ... then with no nutrients for a few days so guess it may be missing the nutrients thanks for that it's only the third week so hopefully it'll get better - my partner is away so I'm left holding the fort last thing I need is for him to come back to diseased plants!

N def would start at the tip of the leaves and usually turns the leaves yellow pretty quickly, N def does not spread down the veins like this.

Looks like Magnesium Deficiency, heres a pic from a tutorial, looks very similarGood Luck mate, way to fix it----buy Epsom Salts from Chemist/Drugstore add half a teaspoon to a quart of water, give it a good shake to dissolve the crystals and water your plants once, see if it improves.

Motown...use a little epsoms salt in your next feeding. Thats Mag def for sure. If your feeding them store bought nutes at the right strengths mg def. usually doesn't show up at least this early? Tends me to believe you are starting to lockout due to Ph.

What you really need is a Ph pen and a TDS pen, these will allow you to be in the correct zone every time. Cheap ones are 20 bucks, well worth it in my opinion.

Good Luck
