Hi! Do you the pH and ec of the soil? The claws on the leafs looks like nitrogen toxicity and that causes K deficiency (yellowing on the leaf edges). So you might have many lock outs going on with wrong pH or build up salts or just too much nitrogen. You need to flush the soil with good amount of water and give lower doses of nutrients at first and wait until she recovers

you have Nitrogen toxicity going on, Reduce the amount of nitrogen that is being fed to the plants. If you are feeding extra nutrients, cut down that amount. If you are in the flowering / budding stage, make sure you’re using a formula that’s specifically meant for flowering, or else it could have too much nitrogen. If you are not feeding extra nutrients, you may have “hot” soil that has been giving your plants extra nutrients. In that case, flush your plants with filtered, pH’ed water to help clear out the extra nitrogen. Effected leaves likely won’t recover, but you should see the problem halt with no new leaves being affected.
